Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

Imagine recycling food scraps and using them to make paper. The directions are all here in a seven-page packet that details several paper-making strategies.

Did you see that or did I imagine it? Optical illusions are often created with mirrors and lenses, and here is a presentation that covers many different types of mirrors and lenses and how they work. Flat, concave, and convex mirrors, as...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final activity of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids....

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

Students review the components of the scientific inquiry method. In groups, they develop hypothesis on a variety of different topics and design an investigation or experiment to test it. They share their conclusions with the class and...

Students work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...

Pupils use Internet research, articles, discussion and models to explore the dynamics of a tsunami. They focus on the 2004 Asian Tsunami and create posters illustrating their understanding of this phenomenon.

Students examine macro-invertebrates in order to better understand their link to the food web. Working in groups, they record observations of several areas of a stream or river, collect samples from the river bottom, and identify the...

Learners investigate the characteristics of different soil samples. In this physical science lesson, students play the role of forensics solving a crime by matching soil from the suspect's shoes. They formulate a conclusion after testing...

Students investigate magnetic permeability and saturation. In this physics lesson, students explain how current carrying wire coils create magnetic forces. They interpret normal magnetization curves.

Students build simple electromagnetic reed switch motors. In this physics lesson, students explain how it works. They cite real world applications of reed switches and relays.
