This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

Find an answer to the age-old debate of whether life exists on Mars. Groups determine criteria to help look for signs of life on Mars. The activity has the class simulate testing Martian soil samples for signs of life before drawing...

Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.

Students analyze how medical devices that help the human body function. They work in pairs or groups to draw multiple views of the medical device and describe how engineering is used by biomedial engineers.

Students investigate energy sources by examining photographs.  In this atomic energy lesson,  students identify and describe various pictures and how atomic energy is used in them.  Students create a presentation...

Learners investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air...

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students analyze the optical region of the electromagnetic spectrum.

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate instructional activity, students define the idea of radiation "half life" and determine if low doses of radiation are...
