In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners are invited to imagine the park of their dreams!

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

Build and test a scale model of a rainforest canopy walkway.
