In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this activity, learners discover how hard their hearts work to pump blood.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this activity, learners explore how boats are engineered to achieve speed.

How many colors make black? Gather as many water soluble black markers as you can find.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In this activity, learners will build an instrument from common household items. Explore sound through vibrations created by your vocal chords and captured by an instrument.

Play with a slinky and make transverse waves. In this simple Exploratorium Science Snack, learners will experience making waves and will learn the different parts of a wave.

In this activity, learners will construct an air cannon as a model for the human ear.
