UV - More Than Just 2 Letters in the Alphabet

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

The electromagnetic spectrum includes everything from very powerful gamma rays (which are used to treat cancer) to much weaker radio waves (which include microwaves). Through a hands-on activity, scholars explore the temperature...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Light waves and sound waves are the focus of this science instructional activity designed for 5th graders. Besides discovering how these waves travel, learners also discover the basic properties of waves, and analyze data tables and...

Plenty of background information about how air pollution affects much more than just our lungs is included on this attractive handout. After reading, pupils make a working model of a lung and diaphragm. Junior physicians place a small...

A PowerPoint and an accompanying worksheet introduce young meteorologists to the hole in the ozone layer. Another handout provides a coloring and graphing activity which examines the changes in the ozone. There are also links to neat...

Learners work in groups to define and research the terms: ozone, troposphere and stratosphere. Students watch videos, conduct Internet research, participate in discussion groups and complete worksheets.

Students discuss different ways engineers use light. In this engineering lesson, students are introduced to the properties of light and the way light is used. They view a demonstration of light waves using a slinky, and practice using...

Third graders utilize the scientific method to explain light and optics in this five lessons unit. Through experimentation and discussion, 3rd graders canvass the concepts of light traveling, reflection and refraction.

What do science scholars need to know about electromagnetic radiation? Get in depth with standard PS4B from the Next Generation Science Standards. The narrator discusses the parts of the electromagnetic spectrum, wave and particle...
