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

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

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 physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

"Exploring the Solar System: Hide and Seek Moon" is an engaging way for early childhood learners to experiment with some of the tools scientists use to study objects that are very, very far away, and

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.
