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 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.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

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