In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this activity (Lesson 1), learners work in groups to create tide simulations.

This activity (on pages 21-32 of PDF) has learners act out several classic brain teasers.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

In this game, learners cross off or color bingo squares in response to questions about their traits.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
