EDP Steps Used In This Activity

Identify, Investigate, Create, and Test


Challenges youth to use multiple mirrors to see around obstacles and to create handheld periscopes.

Quick Tips

* Consider assigning roles for group members to keep everyone focused on the challenge.
* If youth are familiar with these concepts, consider setting up the periscopes and obstacle course as stations where they can move freely between activities.

End of Activity Engineering Reflection

Today, we investigated the properties of light with mirrors. Scientists and Engineers use mirrors as a remote sensing technology to collect information from a distance.

Key Take Away

We can use mirrors to see objects from a distance and around obstacles.
