2. Amur Leopard This rare subspecies of leopards lives far from the jungle, in eastern Russia. Lots of money is payed by poachers for its beautiful spotted skin, there are now fewer than 100 Amur Leopards in the wild — the latest population count estimates say less than 60 remain. This big cat can run at speeds of 37 miles per hour, and can leap up to 19 feet horizontally and 10 feet vertically. 1.Addax Also called the white or screwhorn antelope, the Addax once roamed all over Northern Africa. The species is known for its long, twisting horns that measure up to 33 inches. Today there are an estimated only three individuals left living in a wild conservation area in Niger. This leaves me with these questions: Why are these animals so rare?

2. Tsetse Fly The Tsetse fly is considered the most dangerous fly in the world. This fly is around 0.5-1.7 cm which is the same size of your average house fly. The Tsetse fly is most found in sub Saharan countries such as the Democratic Republic of the Congo, and Angola. While the flies themselves are nasty bloodsucking bugs that usually feed during the peak warm hours, their true terror lies in the protozoan parasites they spread known as Trypanosomes, a disease marked by neurological and meningoencephalitis symptoms including behavioural changes, poor coordination, as well as the disturbances in sleeping cycles that give the illness its name. It can cause death if untreated. 1. Mosquito Registering in at just three millimeters at their smallest, the common mosquito, even tinier than the tsetse fly, ranks as the second most dangerous on our list due to the sheer amount of deaths each year attributed to the various pathogens carried by several of the more than 3,000 species around the world. Found in every region on the planet except Antarctica, the irritating insects—primarily those from the genera Aedes, Anopheles, and Culex—are the primary vectors of diseases such as malaria, Chikungunya, encephalitis, elephantiasis, yellow fever, dengue fever, West Nile virus, and the Zika virus, which collectively afflict an estimated 700 million and kill roughly 725,000 people each year. According to the W.H.O half of the human population in the world is at risk from these bugs. This leaves me with these questions: What do dinosaurs actually look like?

What is glass made of? Glass is made of liquid sand. Liquid sand is sand that has bean melted. if you let that sand cool it will look like the exact same sand you would find at the beach, except the sand grains are basically ice cubes. How is glass made? First you must heat ordinary sand until it melts and turns into a liquid. If you are wondering why sand doesn't melt in deserts is because sand only melts at really high temperatures like 17000 degrees. Once the sand is melted, it is either poured into molds to make bottles, glasses, and other containers, or, it is "floated" (poured on top of a big tub of molten tin metal) to make windows or glass. Unusual glass containers are sometimes made by "blowing" them. A lump of molten glass is wrapped around an open pipe, which is slowly rotated. Air is blown through the pipe's open end, causing the glass to blow up like a balloon. Glass makers use a slightly different process depending on the type of glass they want to make. Usually, other chemicals are added to change the appearance or properties of the finished glass. For example, iron and chromium based chemicals are added to the molten sand to make green-tinted glass. This leaves me with these questions: What is sand made of? How hot does liquid sand? Is there an alternative of sand? References: https://www.explainthatstuff.com/glass.html I chose this topic because I have nasal congestion.
What is nasal congestion? Nasal congestion is when the nasal passages become inflamed, the blood vessels in the nasal passages start to swell which does not allow air to flow through. What causes nasal congestion? There are many ways that cause nasal congestion. Here are some reasons: Sinus infection, alcohol, allergies, inflammation of nasal cavities, cold, overuse of nose spray, dry air, enlarged adenoids, spicy food, bacteria, hormonal changes, pregnancy, medication for high-blood pressure, tobacco, and stress. How can we stop nasal congestion? There are many ways that can stop nasal congestion. Here are some examples: Taking a hot shower (help decrease nasal congestion The steam from the shower can help mucus drain from the nose), a saline spray (help decrease tissue inflammation in the nose and reduce stuffiness), flush out the sinuses using salt water, eucalyptus oil (made from the leaves of the eucalyptus tree), use decongestant medicine, use a humidifier, and stay hydrated) This leaves me with these questions: What is mucus made of?

What is an Earthquake? A sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic How are Earthquakes caused? An earthquake is usually caused by tectonic plates that collide and start pushing together, eventually one plate goes over the other and pushes the ground over it up, this is caused mountain building. This can cause volcanic eruptions. Imagine the plates had feelings, when one plate goes over the other the plate start to fight until one of them give up. These plates fighting cause large vibrations that cause the ground to shake really hard. Another cause of earthquakes are volcanic eruptions, the vibrations caused from the explosion cause the ground to shake really hard. How do they measure earthquakes? Earthquakes are measured on the Richter scale. The Richter scale measures the magnitude of an earthquake (how powerful it is). It is measured using a machine called a seismometer which produces a seismograph. This leaves me with these questions: How are mountains made? How are tornadoes caused? References Oxford dictionary https://www.quora.com/What-causes-earthquakes I chose this topic because I was watching youtube and I came across nanotech and started wondering what it is.
What is nanotechnology? Nanotechnology is not a micro robot. It is just technology that is very small and instead of using CM and M they use NanoMeters. There are 1000000000 Nanometers in one Meter. The dimensions of nanotech is from 1-100 NM. Depending on what you are adding the nanotech onto will depend on its code like any other device. Nanotech is used to help change the structure of an atom or molecule. All forms of matter behave differently at the nano scale. Ex: The atoms of a nano piece of yarn will behave differently than the atoms of a normal piece of yarn. Ex: A strand of human DNA is 2.5 nanometers in diameter. What is nanotech used for? Nanotech is being used for many things in the environment such as: cleaning pollution, improving manufacturing to create less pollution, and to find different energy sources that are better for the environment and are more cost affective. Fun Fact: The University of Toronto is testing using nanotech to figure out where cancer cells thrive most. This leaves me with these questions: Who is the creator of nanotechnology? Are nanorobots a thing?

Then I started to wonder how they fit all that information on one small circle that is not much bigger than my hand and is thinner than a dime.
What is a disc made of? Disc have 2 parts, The first part is the surface, and the second part is the core. The core is made up of 2 parts the first one is Aluminum and the second one is Magnesium. 96% of the core is made of Aluminum and 4% is made of Magnesium. Magnesium is only there to strengthen the Aluminum. They use Aluminum because it is very cheap and is non-magnetic. Since it is non-magnetic it will not interfere with the data storage on the surface. Now for the surface of the disc. The surface is also made of 2 elements, those 2 elements are: Nickel, and Phosphorus. The surface is made of 90% Nickel and 10% Phosphorus, Since the Nickel is very hard and needs a really high polish it makes the surface really smooth. Nickel is very responsive to magnets(ferromagnetic), so this must be where the information is stored. Since there is Phosphorus the Nickel becomes non-magnetic. The Nickel would be magnetic if there was less then 8% of the Phosphorus. There are actually three elements Nickel, Phosphorus, and Cobalt. Cobalt is also ferromagnetic but is not affected by Phosphorus. Therefore Cobalt is where the information is stored. How do disks work? The CD(Compact Disc) drive shines a laser on the disc and detects reflective areas and bumps. It then converts those bumps and spots into binary code so that it can read the data on the disc. This leaves me with these questions: what is the difference between a hard drive and a disc? Did lasers always read discs?

What is an allergy? An allergy is when someones immune system reacts to a substances. The substances are called allergens. What happens when you have an allergic reaction? When you have an allergen goes inside the body it sends an antibody response. The antibodies connect to cells called mast cells. When the antibodies come in contact with the allergen the mast cells release substances, One of the substances is histamine. Histamine creates the irritation. The most common allergens in Canada are: Peanuts, Tree nuts, Shellfish, Soy, Wheat, and pollen. Which areas of the body are usually affected? Depending on which allergen and where it makes contact with the body will depend on what the symptoms are. The most common symptoms are: eyes (swelling, watery, itchy), nose (stuffed, itchy), and throat (itchy, sore). This leaves me with these questions: How do we get allergies? What is the worst symptom of an allergy?

There are approximately 600 ingredients in cigarettes. When burned, cigarettes create more than 7,000 chemicals. At least 69 of these chemicals are known to cause cancer. Here are a few of the chemicals in a cigarette: Acetone—found in nail polish remover, Acetic acid—an ingredient in hair dye, Ammonia—a common household cleaner, Arsenic—used in rat poison, Benzene—found in rubber cement and gasoline, Butane—used in lighter fluid, Cadmium—active component in battery acid, Carbon monoxide—released in car exhaust fumes, Hexamine—found in barbecue lighter fluid, Lead—used in batteries, Naphthalene—an ingredient in mothballs, Methanol—a main component in rocket fuel, Nicotine—used as an insecticide, Tar—material for paving roads, Toluene—used to make paint. How do E-cigarettes work/what is in them? Most e-cigarettes are made up of four different components, these components are: A cartridge that holds a liquid solution (e-liquid) containing varying amounts of nicotine, flavourings, and other chemicals, a heating element (atomizer) which is the power source (usually a battery),and a mouthpiece that the person uses to inhale. In many e-cigarettes, puffing activates the battery-powered heating device, which vaporizes the liquid in the cartridge. The person now inhales the vapor (which is called vaping). What is the difference between a cigarette and an E-cigarette? There is not much of a difference between the 2 except that an E-cigarette is electrically powered while a cigarette is not. Also, and E-cigarette has 3 times the amount of nicotine inside. This leaves me with these questions: What is the use of tobacco in cigarettes? Is there tobacco in an E-cigarette? Are many of these chemicals actually edible? How do they get carbon monoxide in the cigarette.

What is crude oil made of? Oil was made over millions of years from tiny plants and animals, called plankton. The plankton on the left would form oil in about 150 million years time if the sea bed is not disturbed.The plankton that lived in the Jurassic period made our crude oil. This was the time of the dinosaurs. It was about 180,000,000 years ago. When plankton die, they fall to the bottom of the sea. The plankton are trapped under many layers of sand and mud. Over millions of years, the dead animals and plants got buried deeper and deeper. The heat and pressure gradually turned the mud into rock and the dead animals and plants into oil and gas. What is water made of? Water is only made up of two atoms. These atoms are hydrogen, and oxygen. Water is represented as H2O. Why don't water and crude oil mix? Water molecules are polar – they have a small positive charge at one end and a small negative charge at the other end, and they stick to each other. Oil molecules are non-polar they have no charge. Because of this, oil molecules are more attracted to each other than to water molecules, and water molecules are more attracted to each other than to oil molecules. This leaves me with these questions: Is there anything smaller than an atom? Is sound made up of atoms?

I know that baking soda and baking powder do not produce flavour so I wonder why it is so important.
What is baking soda made of? Baking soda only has one ingredient, sodium bicarbonate a leavening agent(causes dough to rise). Sodium bicarbonate is a powder substance that immediately reacts to acids such as yogurt, buttermilk, vinegar, etc. What is baking powder made of? Baking powder is used as a chemical leavening in baked goods. Baking powder is made of many substances, the main requirements of baking powder is baking soda, cream of tartar, and cornstarch. Cream of tartar is not the same as tartar sauce. Cream of tartar is what you put in baked goods and cleaning solutions, while tartar sauce is a sauce made of mayonnaise. What is the difference between baking soda and baking powder? Both baking soda and baking powder are leavening agents, which means they are added to baked goods before cooking to produce carbon dioxide causing the baked goods to rise. Baking powder contains baking soda, but the two substances are used under different conditions. When you put the baking soda with very little liquid ingredient it will react instantly, but when you you add baking powder it takes a lot more liquid for the baking soda to react because of the cream of tartar. The cream of tartar slows down the process by freezing the baking soda so that it puffs instead of spreads. The main difference is that "soda spreads and powder puffs." This leaves me with these questions: What were to happen if you didn't put baking soda in baked goods? What were to happen if you didn't put baking powder in baked goods?

Then when I go to brush my teeth to get the sugar off I always wonder how the fluoride kills all the sugar.
What is fluoride? Fluoride is a mineral found in your bones and teeth and is also found naturally in, water, soil, plants, rocks, and air. Fluoride is commonly used in dentistries, toothpaste, and mouth rinses, cleaning agents, pesticides, and creating steel. Why is fluoride good for your teeth? Fluoride is good for your teeth because it helps rebuild tooth enamel ( The outer layer of a tooth.), slow down the loss of minerals from tooth enamel, reverse early signs of tooth decay, and prevents the growth of harmful oral bacteria. When bacteria in your mouth break down sugar and carbs, they produce acids that eat away at the minerals in your tooth enamel. This loss of minerals is called demineralization (demineralization is when minerals are lost from something). What are the side affects of fluoride? Here are some of the side affects of fluoride. Dental fluorosis: dental fluorosis happens when you consume too much fluoride while your teeth are still forming under your gums. This results in white spots forming on the surface of your teeth. Other than this, dental fluorosis does not cause any harm to the teeth at all. In fact it actually makes you look more healthy! Skeletal fluorosis: skeletal fluorosis comes from fluoridated water and is very much like dental fluorosis but instead of changing teeth, it changes bones. Skeletal fluorosis can alter the structure of a bone and cause calcification and inflammation the symptoms are joint stiffness, and pain. This leaves me with these questions: Is fluoride actually good for us? What happens to animal teeth when they eat food? Do animals get plaque from eating?

What is the periodic table? The periodic table is a table of chemical elements arranged in the number of protons and nuclei. They are put in rows with other elements with similar atomic structure. Who created the periodic table? In 1869 a Russian chemist named Dimitri Mendeleev started the creation of the periodic table by arranging chemical elements by atomic mass. In 1894 Sir William Ramsay and Lord Rayleigh discovered the noble gases, which were added to the periodic table. In 1897 English physicist J. J. Thomson first discovered electrons - small negative charges surrounded an atom like a shield. The number of electrons was added to the top left corner of the elements box. In 19911 Rutherford and German physicist Hans Geiger discovered that electrons orbit the nucleus of an atom. This leaves me with these questions: What are elements? How do scientists know what kind of element it is? Why was the periodic table created?

What happens when you break a bone? When you break your bone it is called a fracture. The different types of fractures are: complete fractures when your bone is split in half, greenstick fracture is when your bone breaks on one side, buckle fracture is when the bone is twisted on one side with a crack, stress fracture is when a small piece gets chipped, growth plate fracture is when a growing bone is broken, comminuted fracture is when the bone is broken into more than 2 pieces, and a compression fracture is when the bone collapses. How do broken bones heal? After the bone is broken a blood clot develops around the bone to protect it and deliver cells needed for healing. After that, healing tissue forms around the bone as a bandage. The tissue grabs the broken pieces of the bone and starts to stick them together. Finally, after a month or so the bone is finally healed. How do casts help heal the bone? Casts do not help the bone heal they just keep it in place so that is can heal naturally. Before they put on casts they have to take an x-ray of the bone to line up where exactly the bone is broken. This leaves me with these questions: What are bones made of? Do you need a cast for all broken bones?

But then I saw someone walking in snow shoes and started wondering, how do snow shoes work.
A snowshoe is footwear for walking over snow. Snowshoes work by spreading out the weight of the person over a larger area so that the person's foot does not sink completely into the snow. Snowshoes are mainly used today for recreation, primarily by hikers and runners who like to continue their hobby in wintertime. Snowshoeing is a recreational sport. There are many different types of snowshoes, there are, Alaskan snowshoes which are very long and skinny with upturned toes like skies, Bearpaw snowshoes are more compact like an oval, and Beavertail snowshoes are like teardrops and tennis rackets. When we wear snowshoes they not only match the size of your foot but they also have to match the the size of the shoe with how much you way. This is so because, the snowshoes spread our weight out when that are big enough for us but when that are not, they will just be pointless. Origin of snowshoes. In 4000 B.C., people living in Central Asia needed a way to hunt and migrate even when the snow was as high as their waist. It wasn't a matter of convenience, it was a matter of survival. So, 6,000 years ago, these people strapped flat materials to the bottoms of their feet, which allowed them to walk around as if they were floating on the snow This leaves me with these questions: Who created snow shoes? How did it become a sport?

Then I started to wonder what causes a bruise.
What are bruises? A bruise is simply when the blood vessels underneath the skin pop and the blood goes to the skin tissue causing the tissue to suck up the blood making it swell. Bruises form when the soft tissues of the body get bumped. When they do, small veins and capillaries (the tiniest blood vessels) under the skin sometimes break. Red blood cells leak out of these blood vessels. These red blood cells that collect under your skin cause that bluish, purplish, reddish, or blackish mark. The phase of bruises.

I chose this topic because I like using computers to do work and wanted to know how they process all the information.
The primary part of the work is done in the Central Processing Unit or, CPU. The CPU is an extensive circuitry that performs stored program instructions. All computers must have a CPU. A CPU is made up of 2 parts, the control unit and the arithmetic/logic unit or. the ALU. The control unit carries out the plan through very specific programs. The control unit is like a conductor of an orchestra, instead of actually playing the song it tells specific people to do different things. The control unit must connect with the ALU and memory for the plan to be executed. The ALU has the electronic circuitry to execute the needed operations for the plan. The memory chip of a computer is also known as primary storage, primary memory, or main storage. The memory holds and stores data and instructions for processing. There are two different types of memory, 1.the short term memory, and 2. the long term memory. The short term memory is used when you watch a video or play an online game while the long term memory is used when you download a game or video. This leaves me with these questions: How do you charge a computer? How do computers get old? What did the first computer look like?

What are stars made of? There are 3 things that stars are made of: carbon, oxygen, and hydrogen. Astronomers have special telescopes that allow you to see what that specific star is made of. Each one of the colours represent the different atoms. When there is more green that means that there is more oxygen, carbon shows up blue, and hydrogen red. Now that scientists know what the star is made of, they can use that to figure out: how old it is , how much it weighs, and when it will explode. What is the life-cycle of a star? Stars are made up of gas and dust. Nuclear reactions give the star energy to shine brightly for billions of years. The bigger the star the shorter life span it has because it has to burn more energy. Eventually the hydrogen that powers the star will lose fuel and die out causing the star to shrink then explode. This leaves me with these questions: Can a black hole suck up the galaxy? What happens when a star explodes?

Although they barely use fossil fuels, there are so many people, which means so many cars and gas stoves, which causes pollution because of all the gas from the machines. The reason India is so polluted is because they are not as technologically advanced and may not have the amount of money needed to create electric stoves and/or electric cars.
What are fossil fuels? Fossil fuels are formed form organic remains of prehistoric plants and animals. These remains are converted by heat and pressure form the Earth's crust and turn into fossil fuels. Fossil fuels are non-renewable. Why do fossil fuels pollute the earth? When fossil fuels are burned they release pollutants into the air that is harmful to living things. These pollutants are smoke, carbon monoxide, carbon dioxide, and sulphur dioxide. Smoke creates soot which can damage buildings, and plants. It can also make it hard for animals to breathe. Carbon dioxide can cause global warming. Carbon monoxide is a poisonous gas and can kill living things within minutes, and sulphur dioxide can cause acid rain which can burn things down. This leaves me with these questions: Is it possible to make a device that sucks up pollution? Can pollution be contained and turned into something useful? References:

Now let us start talking about bones. How many bones are in your body? At birth you have 270 bones but as you get older bones start to fuse together, by the time you are fully grown adult you have 206 bones. There are 64 bones in the upper extremity(arm+hand). They consist of 10 shoulder and arm, 16 wrist and 38 hand bones. The human spinal column is made up of 33 bones : 7 vertebrae in the cervical region ( neck) 12 in the thoracic region(Rib cage) 5 in the lumbar region(lower back) 5 in the sacral region(upper tail bone) 4 in the coccygeal region(lower tail bone) The pelvic girdle, is made up of 3 fused bones: the ischium, the ilium, and the pubis.

According to Quara sports cars tend to have more abilities, are faster, lighter, lower and built of better materials. Sports cars are made of carbon fibre, while an suv or van is made of steel. Carbon fibre cost $150 a pound, while steel costs $75 a pound. The Hennessy venom F5 is the fastest sports car in the world and can go 484.413 km/ph.

I bring it because I like having my food warm.
Thermoses would just be regular containers if they did not have a vacuum. There are 2 types of vacuums, the first type is a vacuum that is used to clean the kitchen. The second type is a place where there is no air (think of it as space). Thermoses have the second type of vacuum. A thermos has 2 layers, The first layer is the part that holds your food. The second layer is after the vacuum (it is the part you hold in your hand. Think of the second layer as a barrier around the vacuum so that no air comes in. What is convection? Convection is where warm gas or liquid goes to the cold gas or liquid. In a thermos the warmth from the food or drink can not escape or move to the cold parts because there is no air acting like a vehicle to move the warmth toward the cold. Fun fact: A thermos is also called a vacuum flask. This leaves me with these questions: Is there air in space but no oxygen? What is the difference between air and oxygen?
