Mr Clark's
Science Show Off Page

This page was created by students in Enrichment Class Number 10 at Haywood Middle School. These outstanding and advanced students included: Daniel B., Tyler B., Lapatra C., Audrey D., Shelby H., Quaserica H., Brandi H., Jamira J., Alecia J., Mary-Will K., Ashley M., Infiniti P., Tyrese S., Christian S., Jaleel T., Cody C., Martavius M., Dejay G., and Ashley S.   I served as their advisor; however, all the ideas, planning, video, and experimentation was completed by students. We hope that this web service project will benefit our school system, the community, and students of science everywhere. This page contains simple science demonstrations that can be duplicated by elementary and intermediate school students. These experiments are not new or original material, and they can be found in many places. What makes them special is that they were planned, performed, and filmed by our middle school students. Many experiments on this page will include our amateur videos of the demonstrations. The simple instructions should make it easy to duplicate the experiments in your classes or at home. At the bottom of the page there are hundreds of more experiments you can try if you wish to learn a little science! Public educators and their students may use our work product for educational purposes; however, all other rights are reserved.rclark

Mr. Clark on Safety

SCIENCE is Fun; however, it can also be dangerous and messy. So just like the students in this enrichment class, safety precautions should be followed for all experiments.
(1) These experiments should be conducted with an adult present.
(2) Some ingredients like food coloring or soap could damage your clothing or a carpet so wear a lab coat or even an old shirt. Dont forget to protect counters and floors with plastic or newspapers.
(3) A fire extinguisher should be readily available for experiments that involve matches, lighters, or flame.
(4) Some ingredients like vinegar, soap, and light acids could damage your eyes or skin, so wear your protective goggles and latex gloves when necessary.
(5) Experiments sometimes involve heat, force, or pressure. Please follow the directions if they ask you to stand back, move away, or do the experiment outside.

Have fun and learn a little science! But please be careful and safe!

Required Legal Stuff: All science demonstrations and experiments should be performed with adult supervision and should include all possible safety precautions. This class at Haywood Middle School, The haywood County School System, or this instructor are not responsible for the experiments or your safety. Any links within are not under the control of our class, Haywood County Schools or our web provider, Teacher By Moonlight. They are offered as a courtesy, and we are not responsible for them. If you find a link that does not work, has changed, or is inappropiate please inform us.

Chop Stick Through a Balloon
Without a Pop!


No Balloon pops!
View our class video.

 

 

Materials Needed: Latex Balloon, Chop Stick or Skewer, vegetable oil

Demonstration Instructions:

Blow up a balloon to where it’s just short of being full.
(The two ends should be dark.) Make a knot at the opening of the balloon

Take a chop stick, and dip it’s pointy end in vegetable oil.
( 1 inch of the end should be well soaked.)

Stick the wet end into the (dark) bottom of the balloon, twisting as you go.

Then, still twisting, stick the same end through the (dark) opposite end.

 

 

The Science that Makes it Work: The balloon will not pop because the polymers in the latex haven’t been stretched as far as they can go. Thus they can still stretch and hold air around the chop stick. The vegetable oil and balloon polymers combine to reseal the holes and retain the air.

Film Canister Rockets

Can Mr. Clark get the plastic film canisters in the air? Watch our class video.

 

Materials Needed:        
One empty 35mm plastic film canister and lid.
(The white canisters work much better than the black ones do because the seal is tighter.)
One fizzing antacid tablet (such as Alka-Seltzer)
Water
Safety Goggles

Demonstration Instructions:

Put on those safety goggles and head outside - that film canister really flies high! If you want to try the indoor version, do NOT turn the canister upside down in step 5.

Break the antacid tablet in half.

Remove the lid from the film canister and put a teaspoon (5 ml) of water into the canister.

Do the next 2 steps quickly!

Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.)

Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 meters.

About 10 seconds later, you will hear a small pop of releasing pressure and the film canister will launch into the air!

Caution: If it does not launch, wait at least 30 second before examining the canister. Usually the cap is not on tight enough and the build up of gas leaked out.

The Science that Makes it Work: When you add the water it starts to dissolve the Alka-Seltzer tablet. This creates carbon dioxide. As the carbon dioxide is being released, it creates pressure inside the film canister. The more gas that is made, the more pressure builds up until the film canister is blasted up. This system of thrust is how a real rocket works whether it is in outer space or here in the earth's atmosphere.

Milk Colors Run for Their Lives.

Watch the colors scatter!
See our class video



Materials Needed: Shallow Plate,Milk (not skim milk real milk), Cotton Swabs Food Color, Dawn Soap

 

Demonstration Instructions:

Fisrt fill the shallow plate with milk.

Put a few drops of food coloring near the middle of the plate trying not to make them touch, it does not matter what colors.

Put dawn soap on the end on the cotton swab and place it in the middle of the plate.

With the end that has soap on it in the milk.

Watch the food coloring go every which a way!

The Science that Makes it Work: Milk contains fat, and the liquid soap is used to break down the fat. When you drop the liquid soap onto the plate, it breaks down the fat in the milk. The milk without the fat is flowing up and away from the dawn. The food coloring floating on the milk just helps us visualize this movement.

Make your own SLIME!
See our class video.

 

Recipe one

Materials Needed:
1/4 cup of water
1/4 cup of white craft glue (like Elmer's glue)
1/4 cup of liquid starch (used for clothes)
Food coloring (optional)
Mixing bowl
Mixing spoon

Demonstration Instructions:

  • Pour all of the the glue into the mixing bowl.

  • Pour all of the water to the mixing bowl with the glue.

  • Stir the glue and water together.

  • Add about 6 drops of food coloring.

  • Add the liquid starch and stir it in.

  • It should be non-liquid by now. As you play with your slimy, it will become more stretchy and easier to hold.

  • When you are done, place the slime in a zip bag for safe keeping.

Recipe Two

Materials Needed:
White craft glue
Disposable cups
Food Coloring
Water
Borax Powder
Plastic Spoon
Tablespoon

Demonstration Instructions:

Fill one small cup with water and add a spoonful of the Borax powder and stir
it up. Then set it aside.

Fill the other small cup with about 1 inch (2.5 cm) of the glue.

Add three tablespoons of water to the glue and stir.

Add a few drops of the food coloring and stir it up until mixed.

Add one tablespoons of the Borax solution you made earlier and stir well. Watch the slime form!

After the slime forms let it settle for about 30 seconds and then pull it off the spoon and play with it!

 

The Science that Makes it Work: The glue is a liquid polymer. This means that the tiny molecules in the glue form strands like a small chain. After adding the soap or the starch, the strands of the polymer glue become stronger and hold together, giving your compound its slimy feel.

 

 

Twenty Dollar Bill on Fire but not Burning

Will Mr. Clark get his money back or just the ashes? ( He's rich so it should not matter! lol)
See our class video.

Materials Needed: A Dollar Bill or any Other Demonation, but for Mr. Clark we requested a twenty!
Rubbing Alcohol, Water, Metal Tongs, Lighter

 

Demonstration Instructions:

Put a mixture of half rubbing achhol and half water in a container.

Dip the dollar billl in the container using the metal tongs.

Pull the dollar bill out and tap it against the sides to get a little bit of liquid off.

Light the dollar bill and notice that the dollar bill will flame but It will never catch on fire and turn into ash.

The Science that Makes it Work: Alcohol makes it burn, but our solution had equal amounts of water. The water and alcohol over power each other so we got flame but no burning.

Fizzing and Foaming
Our cup Runeth Over

The Cup will not Hold the Foam.
See our class video.

 

 

Materials Needed:

One Tablespoon of Baking Soda
One Tablespoon of Laundry Detergent
¾ Cups of Water
¼ Cup of Vinegar
S several Drops of Food Coloring (optional)
12 Ounce Drinking Glass
A Water Proof Plastic or Metal Tray
A Teaspoon

Demonstration Instructions:

First you will start out by putting the drinking glass on the tray.

Next pour in everything except the vinegar.

Make sure it is mostly mixed up then pour the vinegar.

As you pour the vinegar, it will start making foam which is really pretty.

The Science that Makes it Work: The vinegar reacts with all the ingredients causing it to foam uncontrollably
