Explore the size relationship between the sun and Earth by using tape and stickers. Learners estimate, then place and count the number of one-inch diameter stickers (representing Earths) that would fit across the diameter of a nine-foot circle of... (View More) tape (representing the sun). The relative size of each becomes visually apparent. Related Next Generation Science Standards (NGSS) are listed. (View Less)

In this activity, students create a scale model depicting the vertical distance from Earth’s surface to various features and objects, including Earth’s atmospheric layers, the Van Allen Radiation Belts, and geocentric satellites. Students also... (View More) compare the vertical distances to these features and objects with distances from their classroom to other common points on the ground. Includes background science information; student reading, handouts and worksheet; teacher information; and suggested extensions and adaptations for students with vision impairment. (View Less)

This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science... (View More) curriculum in grades 5 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be one-pagers with a Teacher’s Guide and Answer Key as a second page. (View Less)

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More) clothesline to model a logarithmic scale, they add in the electromagnetic spectrum. Finally, learners conduct several simple tests to detect other types of radiation. This activity requires access to a sunny outdoor location and the use of ultraviolet light-sensitive beads. (View Less)

This is an activity about perspective. Learners will examine pictures of objects up close and far away to try and figure out what they are. Then, given an image of a star and the Sun and through discussion about the differences and similarities of... (View More) seeing objects up close, learners will use the concept of perspective to relate our nearby Sun to the stars that appear as small points of light in our sky. (View Less)

This is an activity about size and scale. Learners will create and walk through a distance scale model of the size of the Solar System. This activity requires a straight line distance of approximately 295 meters (300 yards).

In this hands-on activity, learners begin by estimating the size of each planet in our Solar System and Pluto and making each out of playdough or a similar material. Then, learners follow specific instructions to divide a mass of playdough into the... (View More) size of each planet and Pluto and compare the actual modeled sizes to the students' own predictions. This activity requires a large amount of playdough material per group of learners. Three pounds is the minimum amount required for each group. (View Less)
