In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

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

In this activity about archaeology, learners will explore different Egyptian hieroglyphs and recognize their meanings and uses.

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

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 chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

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 demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as
