In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

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

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

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

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

Learners will understand the relationship between climate change and sea-level rise.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

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 fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

In this experiment, learners float colored ice cubes in hot and cold water.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.
