Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.

In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners build water-propelled engines from soft drink cans.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.
