In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.
