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

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

Learners use shop tools and various materials to construct a magnetic spinner and a compass.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this activity, learners discover that some things only stand up while they are spinning.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.
