Physics with Mr. Noon: Paper Tower Challenge

Question: Do anyone know any Science Experiments For Kids?

My children (pre-k,kind and 1st grade) have to do Science Experiments.and I’m totally going crazy.Any and all help will be appreciated..Thanks

Answer: 1) get plastic bottles and teach the separation of substances- water & oil, rubbing alcohol & glitter. teach why they don’t mix. put coloring drops in each bottle. put something that sinks, something that stays in the middle and something that floats on top. tell them why. seal the tops with thick tape.
2) plant parts salad- teach the different parts of plants: leaf, stem, root, fruit, flower. get some carrots, tomatoes, celery, broccoli, cauliflower, different lettuces, avocado, etc. and make ”plant parts salads” have them identify the ‘plant parts’ tell them the functions of each part are.
3)have them cut 1” squares out of semi-hard paper and then go outside and on plates put scoops of outside stuff- dirt or sand or grass and have them identify individual things in there and draw diagrams of what they found (bugs, different kinds of rocks, roots, leaves) to raise awareness that many little things make up different environments. or leaves, flowers or wood- and what makes them up. the paper is like a ‘microscope’ they can look through the hole.
4) Get: 2 liter soda bottle and its cap or some other ‘squeezable’ clear plastic bottle, small container such as a large water glass or bowl, glass medicine dropper (one that sinks in water) take the empty soda bottle and fill it completely with water. fill the water glass with water and place the medicine dropper in the glass. get some water inside the dropper by squeezing the rubber bulb while the end is in the water. you want to get the dropper to just barely float upright in the water. once you’ve done this, place the dropper in the soda bottle and screw on the cap tightly. don’t allow much air to be between the top of the bottle and the cap. gently squeeze the bottle. as you squeeze, the diver will dive (sink) to the bottom of the bottle. if you stop squeezing, the diver floats back to the top. demonstrates buoyancy.
5) dispersion experiment. glass bowl, black pepper, liquid soap needed.
get a bowl with water in it. sprinkle pepper all over top. get some liquid soap rubbed on your fingertip. touch the fingertip barely on top in the pepper and watch the pepper zoom to the sides of the bowl. the film of soap pushes it to the side.
6) dancing raisins
pour clear carbonated soda water into a clear glass. drop four or five raisins into the glass. after about a minute, you will observe raisins moving up and down in the glass. watch how the bubbles control the movements of the raisins.
7) volcano: modeling clay, 1 tablespoon of baking soda, red food coloring, liquid dishwashing soap, 1/4 cup of vinegar
set up a work area with newspaper, or have a surface that can get wet. this project can get messy! model your volcano out of brown and green modeling clay. you can use red clay around the rim of the volcano to make it look like flowing red-hot lava. scoop out a hole at the top of the volcano and stir in 1 tablespoon of baking soda, a few drops of red food coloring, and a few drops of liquid dishwashing detergent. when you’re ready for the volcano to erupt, pour in 1/4 cup of vinegar and stand back!
balloon blows up by itself
empty soda or water bottle
balloon
baking soda
vinegar
paper towel
1. tear the paper towel in half. take one half and tear it in half again. You will use one of these smaller squares as your wrapper.
2. place about a tablespoon of baking soda on your wrapper. fold it up and twist the ends closed so that the baking soda is neatly inside.
3. pour about 1/4 cup of vinegar into your bottle, and add the wrapper of baking soda.
4. quickly place the balloon securely over the top of the bottle and watch the balloon blow up by itself!
note: you can swirl the liquid in the bottle to help the two chemicals react once the balloon is fastened to the top.
this experiment works because the vinegar and baking soda mixed together produce a gas which fills the bottle and the balloon. The paper towel is used to protect the baking soda for a short period of time while the balloon gets placed on the bottle.
9) color flowers: white flowers, a vase of water, food coloring
1. put a white carnation or daisy in a vase with 1/2 cup of water.
2. mix 10 or more drops of food coloring into the water.
3. leave the flower overnight, and you’ll see the petals change colors. If you leave the flower in the colored water longer, more color will fill the petals.
the food coloring travels up through the stem by capillary action and leaks into the flower’s petals. If you look closely at the petals you can see the path that the food color and water travel.
10) tornado two 2 liter bottles, tape, water
1. fill one of the bottles about 3/4 full of water.
2. put the empty bottle upside-down on top of the bottle filled with water.
3. tape the mouthpieces together.
4. flip the bottles over so the one filled with water is on top. rotate the bottle on top in a circular motion until a tornado starts to form.
5. set the bottles on the table and watch the tornado in action!

Question: Science Experiment Help PLEASE!?

I’ve been trying to think of something to do… I’m in the 7th grade as well. I wanted to do black holes but that’s to scientific…but i really want something to do with space! Help please

Answer: Black Holes could work, if you know what you’re talking about. Do a drawing or “picture” of a black hole on the background and pieces of yarn to show “spaghettification”.
