In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.

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

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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.

Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Everybody loves messy science, and Flubber is a favorite of both COSI employees and guests!

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this challenge, learners figure out how to make a juice stain disappear.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.
