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

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

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

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.

In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

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.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

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

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.
