Windmills have been around for generations to grind food and create energy. During this challenge, students will use various materials and put their engineering skills to work by creating their own windmills.

This fun and interactive lesson will teach your students the scientific method to find out if something sinks or floats with a little help from Cookie Monster.

One of the basic concepts in science is recognizing that all things can be classified as living or nonliving. In this lesson, your students will explore the characteristics of living and nonliving things with engaging hands-on activities.
