In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

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 activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity, learners explore accuracy and precision.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
