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)

Using stickers created from the templates provided, students create a Venn diagram of objects in our solar system, our galaxy and the universe. This short activity can be used as a formative assessment.

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More)

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)

Learners will construct a pinhole camera and, using the projected image of the Sun, calculate its diameter. After calculating the diameter of the Sun, learners will create a classroom sized scale model of the Sun and Earth. This activity requires... (View More)

This is an activity about the Hubble Deep Field image, an observation of one small area of sky that contained no previously-detected objects. The long time exposure of this image allows us to detect some of the most distant objects seen in our... (View More)

This is an activity about the relative sizes of the Earth and the Moon and the distance between them. Learners will inflate a balloon to the approximate size of the moon in relation to a standard globe. They will then hypothesize as to the correct... (View More)

This is a detailed historical lesson about comets, distant icy worlds often visible to observers on Earth. Learners will consider the essential question, "What are comets?" They will practice observation skills as they enact a story of comets... (View More)

Learners will explore the relationship between angular size, actual size, and distance by using their finger, thumb and fist as a unit of angular measurement. Includes teacher background, student data sheet, and extensions.

This is an activity about the shape of the Earth’s orbit. Learners will first use elements of the orbit of Earth and Pluto and an apparatus using string, a pencil, and pushpins to accurately draw an ellipse, showing the nearly circular shape of... (View More)
