Students explore optical illusions. For this Applied Science lesson, students view optical illusions and record the data of what they see. Students graph the data that they collect.

For this color worksheet, students answer questions involving the visible spectrum. These eleven short answer questions involve wavelength, lux, and the effects of color on mood.

In this comet tails and stars worksheet, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Students explore scientific observations by examining the parts of a microscope. In this optics instructional activity, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a...

Students assess how algebra, telescopes, space exploration and optics are so important in astronomy. They encounter studies on the Hubble Space Telescope, Hubble Deep Field and how algebra helps to determine the effects of contamination...

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

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.

High schoolers experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Young scholars perform an experiment in which they will use a statistical method called `sampling' to count to a billion (and beyond). Students practice sampling by estimating the number of characters on a page from the classified...

Students examine the relationship between three dimensions and two dimensions by working with shadows of cubes and other models. Students work in groups and use Zome System Creator Kits to try and build a shape other than a cube that...

Students experiment with a simple periscope to see how it reflects light. They draw a diagram of the path a ray of light follows as it travels from an object, through the periscope, and into your eye.

In this math worksheet, students Investigate the structure and function of how the numbers of people infected with HIV changes over time. They answer the fact of it either increasing or decreasing.

Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.

Students identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also research the...

Young scholars construct a simple refracting telescope. They calculate the magnification.
