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 game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

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

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

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

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

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

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

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

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.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this hands-on botany activity, learners sprout vegetables in film canisters.

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.
