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

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

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 explore conservation of energy by experimenting with a solar cell light device.

In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

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

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this Cyberchase activity, learners make decoders to send and receive secret messages. Learners make the device out of two 8-ounce cups and two code strips.

Jugando a este juego, los chicos desarrollan habilidades de lógica, geometría, y visualización espacial. Los jugadores empiezan con una red de hexágonos vacía.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this Cyberchase activity, learners play a game where zero can help them win--or make them lose! Learners roll the die and place a zero in the tens or ones place.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this Cyberchase activity, learners play a simple game using 15 paper dragons (or any 15 objects). One of the 15 dragons is red. Learners try to make their opponent take the red piece.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

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

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.
