In this eclipses activity, students read about solar and lunar eclipses to complete 8 short answer questions comparing the two types of eclipses.

Students study classification schemes for identifying sunspots. They distinguish between sunspot unbrae and penunbrae, measure sunspots, and compare them to the size of the Earth. They complete a worksheet showing classification of...

The sun is responsible for almost 99 percent of the solar system's mass. As an essential part of our lives, the sun has many important features. A PowerPoint lesson presents information about features such as sunspots, the magnetic...

In this earthquake exploration instructional activity, learners complete 2 prior knowledge questions, then use "2D Eclipse Gizmo" to conduct several activities, completing short answer questions when finished.

In this eclipse worksheet, students complete a hands on activity where they simulate an eclipse and answer short answer questions about it. Students complete 19 questions.

In this earthquake exploration worksheet, students complete 3 prior knowledge questions, then use "Eclipse Gizmo" to conduct several activities, completing short answer questions when finished.

Do you think Earth makes fun of other planets for having no life? The presentation covers the rotation and revolution of both the earth and our moon. It provides explanations for seasons, tides, and eclipses. Lesson is the 20th in a...

Grub, volu/volv, and umbr form the basis of a vocabulary lesson predicated on these roots. Although the slides may perturb some of your class members, the more voluble will not take umbrage at the presentation.

Students explore solar eclipses by participating in a number of hands-on activities. In class, students work in teams using tennis balls, grapes and flashlights to model partial and total solar eclipses.

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

In this eclipses learning exercise, students are given diagrams of a solar and lunar eclipse. They fill in each diagram with given terms and color the diagram to indicate the process for each type of eclipse.

In this science activity, students find the words that are related to the common science terms. The answers are found using the links at the bottom of the page.

Students are introduced to the ecliptic, the zodiac and the apparent motions of the Sun, Moon and planets across the sky.

High schoolers investigate the celestial sphere and the paths it takes in the solar system.

Kids learn about lunar and solar eclipses in the science of astronomy including the umbra, antumbra, penumbra shadows as well as total, partial, and annular.

This brief animation adapted from NOVA illustrates how total solar eclipses form and explains the stages from first contact to totality. [1:14]

This site provides a moving diagram of a Lunar eclipse, showing Earth's umbra and penumbra and the appearance of the Moon as it passes through these shadow regions.

This site provides a tutorial on using computer image processing techniques to measure the size of sunspots and analyzing various phenomena visible in solar images. It also provides lesson plans for teachers to use in class.
