In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

Do grapes, yes the grapes from the grocery store, move in the presence of a very strong magnet?

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

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

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

In this activity, learners explore how mirrors reflect light and change the way we see things.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this activity, learners perform an experiment to find out what determines a flower's color.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

In this activity, learners discover that sand is the major ingredient in glass.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.
