In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

Learners construct and launch paper helicopters.

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

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

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.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.
