In this math lesson, learners count and compare amounts of money less than or equal to one dollar.

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 math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

Can gelatin (like Jell-O ®) change the speed of light?

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.
