In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity, learners explore how musical instruments are engineered.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
