Elephant Toothpaste

If you are not afraid of a little mess, try making elephant toothepaste. The kids love combingin the ingredients and then wathcing to see what happens.
Supplies Needed:
  • Instructions
  • plastic bottle or cup
  • yeast
  • liquid dishsoap
  • hydrogen peroxide
  • water
  • overflow pan
Example of what the elephant toothepaste science experiment looks like, foam coming out of the bottle or cup.

Walking Water

This is a fun way for the kids to learn about primary and secondary colors. Use the printable lesson provided on the website to help guide the experiment.
Supplies Needed: Example of what the walking water experiment looks like, the colored water travels from the cup through the paper towel and combines with the colored water from the other cup to make secondary colors.

Bubble Explosion

Have fun wathcing the reaction when an acetic acid (vinegar), a base (baking soda), and dishsoap are combined. Instead of the acid and base reacting and releasing carbon dioxide gas, the dish soap traps the gas and bubbles are created. Watch the video below for a full explanation of the experiment.
Supplies Needed:
  • Test tube or container
  • cylinder or cup
  • funnel
  • measuring spoon
  • baking soda
  • vinegar
  • dish soap
  • food coloring (optional)

Rain Cloud in a Jar

A simple experiment that demonstrates how clouds work and rain is produced. Use the printables provided on the site to help guide the kids through the experiment.
Supplies Needed:

Floating Egg

For this experiment test to see if an egg floats or sinks in water and try the experiment again using saltwater. Have the kids make predictions and discuss the results. Listen to the audio or read below for a full explanation of the experiment.
Supplies Needed:
  • Cylinder or clear narrow cup
  • measuring spoon
  • raw egg
  • water
  • salt
side by side photos showing egg floating experiment, left one in plain water sinking and right one in salt water floating (To perform the floating egg experiment, take a cylinder or clear narrow cup (approx. 200ml in size), fill the cylinder with 100ml of water and carefully place the raw egg in the water. Notice in the picture on the left that the egg sinks. Next, remove the egg and add 1 Tbsp. of salt to the water and stir until it is dissolved. Place the egg back in the water and notice that the egg floats this time, as shown in the image on the right. Dissolving the salt in the water makes the saltwater more dense than the egg and therefore, the egg will float.)

Alka Seltzer Rocket

To perform the experiment, cutout and tape paper rocket to the film cannister with the opening at the bottom of the rocket. Fill the cannister 1/3 full with water, add a piece of an alka seltzer tablet, secure the lid on the cannister, shake the cannister, place the rocket on the ground, stand back and watch. For a fun demonstration or additional information, watch the video below or even check out Science Bob's website.
Supplies Needed:
  • 35mm film cannister and lid
  • Alka Seltzer tablet
  • Water
  • Construction paper and tape (optional)
