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 of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity learners will create paint out of natural materials. Explore your natural world (or your fridge) and find berries, leaves, or flowers to find a great base for your paint.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners of all ages will experiment with paint and printmaking.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

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 capture and observe planaria, which are worms that eat tiny pond critters.

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