Learners explore water's property of cohesion through two investigations.

This lesson focuses on how materials behave differently as their surface area increases.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners discover that some things only stand up while they are spinning.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners investigate the properties of different types of balls.

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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
