In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

Millions of organisms can live in and around a body of water.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
