Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

Learners follow the template to build and fly a paper helicopter.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.
