This activity introduces students to the magnetosphere, which shields the Earth from plasma streaming from the Sun (the solar wind). They will use a bar magnet and iron filings to construct a model that shows how Earth's magnetic field interacts with the solar wind, deflecting the plasma away. A materials list, instructions, and culminating activities are provided. Full description.

The purpose of this activity is to encourage students to learn about lenses by examining them firsthand and observing their similarities and differences. They will examine various lenses and write a description of what each one looks like, what objects look like when viewed through them, and other information that they decide is necessary to enhance their understanding of how lenses change the way ...

In this activity students look closely at a variety of lenses and describe how the they are shaped. The terms convex and concave are introduced for describing types of lenses. As students discover new things about how they look at objects, they will write their discoveries in their science notebooks. They are encouraged to look through the lenses at the pages of a book, their hands, and other objects, ... Full description.

In this activity, students will investigate various aspects of the behavior of light. First, they will use diffraction gratings to view the colors or spectrum produced by visible light, then hold the diffraction grating in front of different light sources and record the colors that they see. They will examine common materials to determine whether they are transparent, translucent, or opaque and use ... Full description.

Infrared radiation, located in that part of the electromagnetic spectrum just beyond visible light, is emitted by all matter and is very useful in gathering data about Earth and space. This video segment introduces students to infrared radiation, its properties, and some of its practical applications. The segment is five minutes forty-two seconds in length. A background essay and list of discussion ... Full description.

Human eyes cannot see infrared wavelengths, but with the help of false-color imaging, temperature differences become visible and invisible features are suddenly illuminated. This interactive gallery shows images of a variety of objects and geothermal features in both visible and infrared light, and explains why the infrared images show the items as they do. A background essay and list of discussion ... Full description.

This resource explores winter weather and frozen precipitation. The page on precipitation points out that snow and rain are both water and explains how the different forms of frozen precipitation (snow, sleet, freezing rain) occur. There is a page on cirrus clouds that explains their characterstics and how they may affect climate by reflecting solar radiation or reducing outgoing infrared energy from ... Full description.

In this activity, students mount a covered mirror on a wall at eye level, then work in pairs to predict where two people must stand so each can see the other's reflection in the mirror. Each pair will discuss and agree on the places where they think they must stand, then remove the cover from the mirror and test their predictions. As an extension of this activity, they can design and construct large ... Full description.

In this activity, students fasten two mirrors together using masking tape and observe the relationship between the angles of the two hinged mirrors and the number of images produced. Students mark angles between 180 degrees and 20 degrees. They open the hinged mirrors to each of the specified angles, place an object between the two mirrors, and count and record the number of images they see. In a ... Full description.
