In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

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

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
