In this activity, learners investigate color vision as well as plan and conduct their own experiments.

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).

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

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

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.
