Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

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

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

The goal of this activity is to design, build and test a house or toy for an animal.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

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

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.

In this activity, learners play a traditional Mexican game of chance with a twist. Learners take turns spinning a special "Toma Todo" top.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.
