In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this physics activity, learners will explore buoyancy.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

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

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
