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 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).

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

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.

In this activity, learners work individually to assemble a product and then work in teams to design, construct, test, and redesign an assembly line process whose product must meet specific quality con

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 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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity, learners will observe a deceptively simple process: a burning candle.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
