Using the size of the planets, 2nd graders are able to work with numbers to 1,000. This lesson introduces larger numbers (even beyond 1,000) to extend student understanding of the patterns in numbers.

The purpose of this activity is to use scaling in order to give students an idea of the size of Mars in relation to the Earth and the Moon as well as the distance between them. The students will have to calculate dimensions of the scaled...

An activity where students build a scale model of the solar system based on a marble they pick from a bowl. After choosing a marble that represents Earth, students must calculate the size of the other planets and the sun. Site includes...

Students learn about the distance and relative size of the rest of the planets compared to the Earth and Sun. The lesson plan includes an assessment and extension activities.

NASA site features a lesson plan that teachers can use to help their students see how far they are from each of the planets.

[Free Registration/Login Required] Students often have a difficult time comprehending the timescale and distances of the universe. I have used this flipchart to start the discussion of the formation of our universe and how we know about...

Teach the concept of scale models and the size of the solar system through this extensive lesson plan. Students will learn about scale models, estimate which objects to use to create a scale model of Earth and Sun, and figure out how far...

In this activity, "You will investigate the concepts of relative size and distance by creating a basic model of our solar system." Planet printouts are provided and this site contains related links.

This lesson will develop a map of the solar system in proportion to the distance between the planets. It is 1 of 3 in the series titled "The Solar System."

Distance and midpoint formulas are explained through the use of examples and a video lesson. [1:58]

Gain an understanding of how to find the distance between two points and the midpoint by viewing examples and a video lesson.

The absolute value of a number a is written as |a| and represents the distance between a and 0 on a number line. An absolute value equation is an equation that contains an absolute value expression. The equation |x|= a has two solutions...

[Free Registration/Login Required] The meteor is orbiting one of the 3 planets in a circular orbit. Drag the point associated with each planet to the meteor to see its orbit around that planet.

Students must calculate the stopping distance for a car traveling on a distant planet.

While astronomers and philosophers have long mused on the possibility of other solar systems, the first planets confirmed to orbit a star other than our Sun weren't found until 1992. The reason it took so long is that it's really hard!...

Celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun, moon, planets or stars. This activity starts with a...
