In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

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.

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

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners use various dress-up or costume pieces to play a game of change.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
