What you need To make the Borax solution use 1/4 cup Borax to 1 litre (1 quart) of hot tap water. Stir well. There should be some Borax left in the bottom of the container. If all the Borax dissolves, add more until no more will dissolve. Let the solution cool.
Good snot is clear and colorless. But when the cilia stop moving, your nose mucus gets clogged. Bacteria, bacteria waste, and other stuff gets stuck. The mucus changes from a clear liquid to gunky green. Where do boogers fit into the snot picture? The mucus coats the hairs inside your nose. The scientific name for nose hairs is vibrissae. When you breathe in, dirt gets trapped in the goopy hairs. The dirty mucus clumps up, dries out with your breathing, and a booger is formed!
What you need Materials for fake
wound:
This blood is nontoxic,
which means you can put it in your mouth and then let it drip out and
say "I want to suck your blood". Have you ever tried a blood milk shake? The Masai people in Africa give blood milk shakes to people who are elderly or ill. The Masai are a herding people. They make a blood milk shake by cutting a vein in the neck of a cow and collecting some blood. Then they mix in some milk. A blood milk shake is actually very nutritious. Maybe you haven't tried a blood milk shake, but have you ever eaten a rare steak? So you have probably eaten blood after all. What color do you think of when you think of blood? Most people think of red. You might be surprised to learn that it is deep blue or purple. When you cut yourself, the blood is exposed to air and it oxidizes. That's a fancy way of saying that it rusts. Blood has iron in it, and iron turns red when it rusts. Have you ever cut yourself? If you cut yourself really badly, get an adult - you might need to see a doctor. But if you cut yourself just a little, how long do you guess it takes before you stop bleeding? On average it takes about 6 minutes before you stop bleeding. The next time you get a small scrape you might want to time it. When you cut yourself, your brain says, ACK! Save me! Your body goes into immediate action. It sends out special cells called platelet cells to the wound site. The cells change and become sticky. They form a net that stops blood from dripping out. Then the macrophages arrive. These are very large white blood cells that look like pom poms. The macrophages actually surround and engulf bacteria, dirt and other foreign invaders. Finally, your body sends out killer cells that come and mop up the dead macrophage and bacteria. The whole time, a dried blood bandage (or scab) is forming. To make the blood,
you goop some petroleum jelly onto a plate. Add some red food coloring
and mix. Add cocoa powder and mix. Place some tissue on the wound site.
Smear the petroleum jelly over the tissue. Mold the tissue until it looks
like ripped skin. Rub in some cocoa powder around the edges so it looks
like it's scabbing over.
What you need A calculator
For the number of breaths in one day, multiply your answer by 24. Now take this answer and multiply it by 365 to find out how many times you breathe in one year. To calculate the number of breaths you have taken in your life, multiply the breaths in one year by your age. For figuring out how much air this is, choose an amount and multiply by 0.5 or one-half. By using the proper answers from your calculations, you can tell how many liters of air you expel each minute, hour, day, year, or lifetime. The next time you
are in the soda section of the grocery store, count how many liters you
breathe in one hour.
What you need What to do
What you need What to do The balloon is your stomach. Pour a small amount of vinegar into the bottom of the balloon, your stomach. Use the funnel to add baking soda to the balloon stomach. Pinch the balloon closed with your fingers at the neck; this is your esophagus. Watch your balloon stomach expand with gas. Unpinch the esophagus to release the gas, or burp. Practice the pinch
release to see whether you can make the belch sound like a real burp.
Your stomach is like
a balloon. The stomach stretches as food, liquid, and air are added. When
you eat and drink, you swallow air; which adds gas to your stomach. When
the stomach digests, it adds acid to the foods and creates gas of its
own. So even more gas enters your stomach. If your stomach builds up too
much gas, the pressure becomes too great. Gas must escape to release built-up
pressure. Burp!
What you need What to do When the water in sweat evaporates, or turns into a gas, it takes away heat. Rubbing alcohol evaporates even faster than water, so you can feel the effects right away. Except for your lips and a couple of the reproductive parts, your body is covered with little sweat producers, or sweat glands. On your palm are more than 2,000 sweat glands in an area about the size of a postage stamp. Sweat glands ooze lots of sweat out of the little openings, or pores, in your skin. Up to a quart of liquid in an average day. Smelly sweat comes from sweat glands located mostly in the armpits but also in the crotch, anus, and a little on the scalp. Until a person gets to be about twelve years old, these glands don't do anything. After age twelve, they start oozing, and they never stop. That's why adults are so stinky, and kids aren't. Dogs don't have many sweat glands, so they sweat by panting. A cat's sweat glands are in the soft pads on the bottom of the feet. Sweating is really
important. It controls your body temperature. When you exercise or when
the outside temperature gets warmer than 87-degrees or when you get really
nervous, your body's air conditioning goes on. The sweat coats the surface
of the skin to remove heat from the body. Evaporation of the water cools
you down. Salts and urea (yur EE a) are left behind. That's why you taste
salty after sweating. It is also why you feel sticky.
What you need What to do Salts, gases, antacids, mucus, chemicals that break down food are called enzymes (EN zimes), and urine. A small trickle of urine enters your mouth from the places in your body that make saliva. These are called glands. Your spit factories are located in several glands. Many tiny glands line the inside of your cheecks and ooze small amounts of saliva. Pairs of spit makers are hidden in front of each ear, under the tongue, and beneath the lower jaw. Spit travels in tubes, or ducts, from the glands to pour spit into the mounth. Think of a liter soda bottle. That's about how much saliva enters your mouth every day. Now think of 190 liter soda bottles. That's how much saliva a hay-eating cow produces daily! Spit is great stuff. It gets food wet so it's easy to swallow. It kills bacteria in the mouth that can cause cavities. It's a natural mouthwash. And it turns starch into sugar. The enzymes in saliva break apart long starch molecules and turn them into short sugar molecules. Life is sweet with saliva around. |
