In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

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 will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

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.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners will observe magnetic properties and sort objects by them. This activity uses everyday items to teach learners about magnetic forces, poles and properties of magnets.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

This is an activity exploring color and color mixing.

In this physics activity, learners will explore buoyancy.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this activity learners will build roller coasters and test them using small balls or marbles.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

In this math activity, learners experiment with the concept of symmetry.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
