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

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

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 explore how the power of the sun can be harnessed to heat and cool a building.

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 explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how musical instruments are engineered.

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

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

This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.

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

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

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

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

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

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