Learners explore water's property of cohesion through two investigations.

Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

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 purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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 collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.
