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 use ABS pipe and an air leaf blower to make a strong shooting machine.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.
