In this lesson, learners will practice graphing and statistically analyzing data.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

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

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.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

This lesson focuses on graphene and its electrical properties and applications.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.
