In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

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

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
