In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

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

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

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.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this math lesson, learners compare products to determine the best product.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners make a barometer, an instrument to measure change in air pressure.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

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