In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

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

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.
