Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

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

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
