Students demonstrate the revolution of the moon around the earth and the effect of its direct alignment in between the earth and the sun.

Fifteen detailed pictures and informative captions delve deep into the exploration of stars—their life cycle and importance in the universe. 

Students analyze line plots. In this weather activity using real NASA data, students discuss how weather affects the way the Earth is heated by comparing different line plots.

In this solar system instructional activity, students read about the planets, asteroids, meteoroids, comets, and the moon. Then students complete 25 multiple choice, 4 true or false, and 3 short answer questions.

Students complete a unit of lessons on our solar system, its stars, and astronomers. They record information in a space journal, design constellations, define key vocabulary, observe the phases of the moon, and create a group planet...

Students engage in a solar system activity, In this activity, students will read aloud as a class about the solar system. The students will then listen to the teacher read a solar system book prior to filling  out a worksheet about...

Students create their own sundial and explore how to read it.

Students construct a model of a comet nucleus using dry ice. They add other materials and describe the features. They complete related exercises on an Internet Web site.

In this solar system worksheet, students complete a word puzzle by determining the terms associated with the 10 statements about the planets.

Students examine the different types of asteroids and how they enter the atmosphere.  In this space lesson students use mashed potatoes to create an asteroid they can eat.

Students identify how models are powerful tools of exploration and that the sizes of the planets and distances between the planets in the Solar System span a large range. They make a sign for each planet they have created in the lesson...

Learners determine the effect of the earth's tilt on the amount of incoming solar radiation throughout the year. They simulate the earth's orbit around the sun using a light bulb and a globe to simulate the seasons. Assessment questions...

High schoolers discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."

Third graders study the features of different moons orbiting the planets. In this astronomy lesson, 3rd graders explore the different phases of the moon using an interactive online website. They compare and contrast the features of the...

In this geometric calculations of solar storms worksheet, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

In this parallax effect learning exercise, high schoolers observe 2 photographs taken of an active area of the sun by 2 STEREO satellites and 1 photograph taken of the same active area of the sun by the SOHO satellite. Students observe...

In this solar storms worksheet, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...

In this black holes instructional activity, students read about black holes and solve 3 problems where they calculate the Schwarschild radius of one, the number of grams/second a quasar luminosity implies for another and the number of...

Students simulate the phases of the moon using a lamp and styrofoam balls. In this lunar phases lesson, students stand around a lamp and act as Earth. They hold styrofoam balls and rotate to show the phases of the moon.

Students explore basic principles of seasonal change, ponder the mechanisms that drive these changes, and perform experiments that show what causes the earth to heat differently during different seasons.

In this Earth's seasons activity, learners study the diagram of the Earth's position as it orbits the Sun at four positions. Students then label the approximate date and season for the Northern Hemisphere at each stage. There is a word...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

Comets are also known as dirty snowballs or icy mud balls. With your super scientists, create a model comet nucleus to discover how they are made and take part in a scientific discussion to learn how it behaves.

Celebrate the arrival of spring with this fun primary grade science unit. Engaging young scientists with a variety of hands-on activities and inquiry-based investigations, these lessons are a great way to teach children about...
