Gelatin Prism
Source Institutions
In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

Cabbage Indicator
Source Institutions
In this fun chemistry activity (page 3 of the pdf), learners use cabbage juice to determine the pH of several substances.

Sugar/Salt Crystals
Source Institutions
In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

Exploring Baking Powder
Source Institutions
In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

Molecules in Motion
Source Institutions
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

Rate of Solution Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.

Moo Glue
Source Institutions
Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Scented Dough
Source Institutions
In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.

Hot & Cold
Source Institutions
In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.

Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Mystery Powders
Source Institutions
In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

Neutralizing Acids and Bases
Source Institutions
Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
