In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this science/art activity, learners create an insignia or emblem for a planet exploration mission.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity, learners construct a simple air pressure launcher for paper rockets.

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

In this activity, learners explore how engineering has developed various means to remove impurities from water.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners explore rocketry and the principals of space flight.
