In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.
