Enrichment Lesson 2: Eyewitness Accounts

Water wheels were first used more than 2,000 years ago, yet now they are only a small part of the energy generation people have come to expect. The Michigan-based energy unit covers the common types of energy used, residential energy...

Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson plan...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

It's time to see the light  with a unit that focuses on light and geometric optics, including concave and convex mirrors. A variety of experiments, worksheets, and online activities are included. 

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson plan...

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of chlorophyl,...

For scholars tired of reading the textbook, this unit includes nine hands-on lessons. Through group work, lab activities, experiments, and even one inquiry-based lesson, scholars apply knowledge about cells, genetics, and biotechnology....

Have small groups in your class construct working hygrometers as an example of the benefits of using sensors in engineering. This lesson can be used during a weather unit when covering humidity or in a STEM lesson as a preparation for...

Teach your class about colony collapse disorder and foster discussion about causes and solutions for the honeybee problem. Class members read and discuss an article and participate in one of two detailed activities about pollination and...

Float like a butterfly, think like a bee! Build a huge hive, hexagonally! Find out the reason that hexagons are the most efficient storage shape for the honeybees' honeycombs. This neat little video would be a sweet addition to your life...
