In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners explore the relative sizes and distances of objects in the solar system.
