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.

This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

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 activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

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 activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

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

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

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

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

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.

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 biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
