Eighth graders are introduced to concepts related to the Solar System. In groups, they participate in an experiment in which they must describe a ray of light and how it travels. They draw a diagram of the electromagnetic spectrum and...

A small card with a dot and an X is held at arm's length and used to show youngsters where their blind spot is. This illuminating little activity is a compact addition to your lesson on the structure of the eye as it explains the part of...

Students experiment with the luminosity of the Sun's light. In this luminosity lesson, students participate in an experiment with luminosity of the sun and flashlights. They make filters and fiber optic sources.

Students describe how the sun's rays produce colors. They describe how water causes the sun's rays of light to bend, producing a rainbow.

Fifth graders analyze optical images. in this optical lesson, 5th graders look at how light reflects and refracts. They discuss different types of lenses and how they change the picture that is taken. 

Students discuss feelings and explore how to recognize how they are feeling.  In this exploratory lesson students discuss conflict and ways to resolve problems. 

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

In this space science worksheet, students read an informative passage about radio waves and the possibility of sending messages in space. The passage describes a "Sounds of Earth" record on the Voyager satellite which contains messages...

In this chemistry worksheet, students determine the order of reactivity toward displacement in each of the series listed. Then they respond to several multiple choice questions as they relate to compounds and solutions. Students also...

For this radiation worksheet, students review the different types of radiation waves that come from space and the different telescopes used to detect this radiation. This worksheet has 17 true or false questions.

Students become aware of some of the objects studied in, and concepts associated with, high-energy astronomy. They do this by participating in card games that teach and review these concepts.

Students using experiments try to demonstrate how observations can be affected by the cycles of night and day.

Students using a slide made out of aluminum foil and pin holes observe visible light.

Students study how images they see are transmitted to the brain.  For this sight lesson students complete several activities that have to do with visual pathways and field defects. 

Students observe different substances under the microscope. In this space science lesson, students identify the different features of SEM images. They formulate a conclusion about the images of Mars meteorites.

Students develop an invisible security system to protect a mummified troll.  In this security system instructional activity students view a portion of Mythbusters and begin their challenge.

Learners observe an activity with Jell-O to learn about optics.  In this investigative lesson students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of light. 

Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.

Students develop a basic understanding of how color is perceived by the eye. They utilize the technique Seurat used to paint A Sunday on La Grande Jatte to create their own paintings.

Students research the Hubble Space Telescope. For this Hubble Space Telescope lesson, students complete a webquest about the Hubble Space Telescope.

Pupils view six optical illusions and explain why the visual system might interpret them the way it does. They explore how illusions distort our sense of perspective, because they deceive us into seeing what we expect to see. Students...

In this Sombrero Galaxy worksheet, students observe infrared images taken by the Spitzer Infrared Telescope and the Hubble Space Telescope. They answer 9 questions about the details of the images such as the radius of the stellar...

Learners investigate the essential concepts of how lenses work to magnify vision, and then build simple telescopes to demonstrate their understanding. They write a description of how their telescope could be improved and how it works.
