Cat's Meow
Source Institutions
In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Gassy Lava Lamp
Source Institutions
In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

What's the Difference between Weather and Climate?
Source Institutions
In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

Sink or Swim?
Source Institutions
Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

Pickle Lab
Source Institutions
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
Breakfast Sweets
Source Institutions
In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

Make a Green Gumball Black
Source Institutions
In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!
Triboluminescence
Source Institutions
In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

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.

Make Your Own Sculpture Dough
Source Institutions
In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

Soda Explosion
Source Institutions
This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

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.

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.
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.

The Nose Knows!
Source Institutions
In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.
