Hubble Space Telescope: 340 miles (550 km) International Space Station: 250 miles (400 km)

Ask students to make a stack of coins reaching the altitudes of the following objects orbiting Earth:.

Students should be able to correctly stack coins to the scale height representing approximately 60 miles.

Students should be able to correctly determine how far 62 (approximately 60) scale miles spans in millimeters.

Students should be able to correctly measure the scale distance bar on the map in millimeters.

This is because Denver is 1 mile above sea level while Los Angeles is close to sea level.

How would the distance to space be different from Denver compared with Los Angeles?Īnswer: The distance to space from Denver is approximately 61 miles while it's about 62 miles to space from Los Angeles.

It takes a lot of energy to overcome gravity for that distance and gain the speed required to stay in orbit (approximately 17,500 miles per hour) once you've arrived.

Why do you think getting to space is so difficult when it’s only 62 miles away?Īnswer: Space is 62 vertical miles away.

Have students stack coins on their map until the height of the coins is equal to the millimeter figure they calculated in Step 3.

Now, students will model the distance from the surface of Earth to space.

For simplicity, students could determine how far 60 miles on the scale bar is in millimeters. There are a variety of ways to find this answer, depending on the math concepts with which students are familiar.

Based on their measurements, students should now determine what 62 miles on the scale bar equals in millimeters.

Ask students to measure the length of their map scale bar in millimeters. Have them find the distance scale bar and identify its scale length (e.g., 50 miles, 100 miles, etc.).

Hand out maps to each student or group.

You can also reference locations students may know that are farther than 62 miles to make a point that those places are farther from them than the edge of space. Share several landmarks, cities, or other notable features that are approximately 62 miles from your school or city. Mention the altitude of the International Space Station and the Hubble Space Telescope. After several responses, tell students that the distance to the edge of space is 62 miles above sea level.

Ask students how far they would have to travel from the surface of Earth to reach space.Credit: NASA/JPL-Caltech | + Expand image (A light year is the distance light travels in a year and is equal to six trillion miles.) Yet the edge of space – or the point where we consider spacecraft and astronauts to have entered space, known as the Von Karman Line – is only 62 miles (100 kilometers) above sea level. Planets are many millions or even billions of miles away, and stars are so far away that their distances are measured in light years. We often think of space as being very far away. In this case, it may help to take a screengrab of the map and access it on the device's photo gallery, so that students don't accidentally change the interactive map view. Students using tablet computers can open a map on the device, lay it flat, and stack coins on the screen.Students can print a map at home, or place a sheet of paper on a computer screen and gently trace the outline of a map and the scale bar.These will be used as a distance reference. Prior to the lesson, identify several landmarks, cities, or other known features that are about 62 miles from your school.Local maps, such as city maps, may have scale bars that are too short (i.e., show too few miles per length of the scale bar) making it impractical to stack coins high enough to display the scale distance to space accurately.

You can also download and print this Los Angeles area map. Be sure to select the printing options that include scale bars. Maps can be printed from online mapping services. Students will need printed maps with a scale bar displayed.Ruler with millimeter markings Management Various coins, metal washers, or other thin stackable items State or county maps with scale distance bars (can be printed or displayed from online maps) OR download Los Angeles area map (PDF) They will then stack coins the appropriate height to mark the edge of space. They will use a map scale to determine the relative distance to space from the surface of a map. In this activity, students will gain a better understanding of where space begins. See tips for remote instruction in the Management section.
