In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners will explore how and why weight distribution works.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.
