In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

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 activity, learners investigate and compare the rate of drying in different conditions.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
