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)

This is an activity about the size and scale of the Sun-Earth system. Learners will take an imaginary trip to the Sun by comparing images of the Sun and Earth at different points in altitude above the Earth. This is to ultimately conceptualize the... (View More)

This is an activity about sampling in astronomy. Learners will make a sampling window in order to estimate the number of stars in the sky visible to the unaided eye. After, they will discuss how to estimate the effect of different variables on their... (View More)

This activity is intended as a review of the concepts presented in the previous activities as well as an assessment of student understanding of the activities. Learners use the review information from the activities as they answer question and then... (View More)

In this activity, learners classify selected objects from the Hubble Deep Field based on their color and shape. They then compare their classification with a chart made by astronomers. This is activity two of four in the Hubble Deep Field Lesson... (View More)

In this activity, the problems and difficulties of determining the distances between Earth and objects in space is addressed. Learners attempt to arrange five objects from the Hubble Deep Field according to their distances from Earth. After making... (View More)
