In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

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.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
