What's So Special about Water: Solubility and Density
Source Institutions
In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

Mix It Up
Source Institutions
In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.
Triboluminescence
Source Institutions
In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

Veggies with Vigor
Source Institutions
In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Dissolving Different Liquids in Water
Source Institutions
In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

Maritime Munchies
Source Institutions
In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.

Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

The Snack Shop
Source Institutions

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

Glowing Pickle
Source Institutions
In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

Temperature Affects the Solubility of Gases
Source Institutions
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Chemistry in the Kitchen
Source Institutions
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.

Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.

Kimchee Fermentation Chamber
Source Institutions
Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

Starch Slime
Source Institutions
Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
Gelatin Optic Fibers
Source Institutions
In this activity, learners make optical fibers out of strips of gelatin.

Frog Eggs
Source Institutions
In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.
