In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
