Students understand that the rotation of the Earth is responsible for the seasons. In this seasonal cycles lesson, students learn how the rotation of the Earth affects the seasons. Students answer questions about the rotation, the...

In this algebra activity, students solve linear equations using one and two steps. They solve systems of equations using substitution and elimination with graphing. There are links for ready made tests and quizzes.

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

Students build a scale model of the Solar System and determine the time other planets take to travel around the Sun in comparison to the time of the Earth's revolution. The velocity of the planets are also determined in this lesson.

Third graders participate in a demonstration of the moon's phases. In this moon phase lesson, 3rd graders watch as the teacher demonstrates moon phases with a bright light and a Styrofoam ball. They answer questions associated with the...

Young scholars calculate their yearly exposure rate to harmful high-energy radiation and cumulative effects over time. They use the information to evaluate the various sources of radiation that are of greatest concern for them.

Learners create schematic diagrams of the new Russian space station module. They compose an imaginary yet realistic series of diary entries from the point of view of an astronaut living on board the completed space station.

Young scholars explore placing a satellite into orbit, then about forces needed to keep an object in orbit. They examine how satellites orbit in elliptical paths and about properties of ellipses. They learn Kepler's 3rd Law of Planetary...

Fourth graders will explore our solar system. In this physics lesson students create a model of the solar system to explore the movement of Earth, the Sun, and stars.

Third graders view a classroom simulation that demonstrates how the Earth's rotation creates day and night.

In this space science worksheet, students use the clues given at the bottom of the sheet to solve the crossword puzzle on our moon. They name another name for the moon and the moon's gravity compared to that of the earth.

A guide to recreating all the phases of the moon out of Oreo cookies with varying amounts of cream filling.  Although a simple activity, there are more involved questions requiring moon cycle and phase comprehension and leading...

High schoolers compare and contrast the orbits of Earth and Mars, locate the planet Mars, and diagram its retrograde motion.

Didn't catch the last solar eclipse? Now every day can be eclipse day, thanks to an interactive lesson from PBS' Space series for middle schoolers! The well-rounded multi-media experience includes video clips, an interactive, and...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

After reading a short excerpt about Mercury, your class will answer four comprehension questions. The worksheet challenges them to fold over the paper and answer the questions without referring back to the excerpt. An answer sheet is...

Students explore day and night and the relationships between the Earth, the sun and the moon. They discuss the ways in which the sun and moon help us. They watch a short video that helps illustrate these concepts.

In this science worksheet, students examine a diagram of the moon revolving around the earth in an elliptical orbit. Students answer 3 questions.

Students explore how the angle of sunlight affects the Earth's temperature and seasons and then apply this understanding to their local situation.

In this speed of light instructional activity, students read about Danish Astronomer ole Roemer and his discovery of the speed of light. Students complete 4 short answer questions based on the reading.

Middle schoolers investigate the motion of Mars. In this space science lesson, students use transparencies to trace the path of Mars through constellations. Middle schoolers discuss the characteristics of the planet.

Students investigate space travel. In this science instructional activity, students discuss the space station and its representation in orbit. They talk about food, travel and survival in space with the correct equipment.

Students explore the planet Earth, outer space, and Earth's axis. They demonstrate reading comprehension skills, including literal meaning, inference and critical analysis.

For this satellite technology worksheet, students read about Low Earth Orbit satellites and the frictional drag from the Earth's atmosphere that causes them to fall back towards the Earth. Students use given data of the years the...
