In this activity, learners model ancient lunar impacts using water balloons.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

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 activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into biodiversity of a given habitat.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this activity, learners construct a simple air pressure launcher for paper rockets.

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.

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