This interactive, online activity allows students to examine the Hubble Deep Field image and simulate the process astronomers have gone through to classify the objects in it. Students classify select objects in the image based on observable properties such as color and shape. Students then compare their classifications to those made by astronomers. Upon completion of this activity, students will have ... Full description.

This is an activity about the properties of light as seen in prisms and rainbows. The activity also focuses on the process used to explore scientific questions pertaining to these topics, thereby developing tools and strategies for student inquiry. Learners will shine two types of light through a prism to create a light spectrum. They will then make observations as to the nature of the "rainbow," ... Full description.

This is an activity about whether different wavelengths (colors) in the light spectrum heat objects differently. The activity also focuses on the process used to explore scientific questions pertaining to this topic, thereby developing tools and strategies for student inquiry. Learners will make predictions about color and temperature. They will then use a prism notched into a cardboard box to generate ... Full description.
