In this interactive, online activity, students explore the nature and composition of comets by selecting and mixing different elements and compounds found in a comet's nucleus. Students then observe the results of their mixtures upon the appearance of the comet and its tail. Upon completion of this activity, students will be able to create their own comets and identify different types of comet tails. ... Full description.

In this lesson, students create a timeline of world events from 1905 until 2006. Students locate key dates from the Cosmic Times poster series and determine world events that fit into the three story strands of Cosmic Times, as well as, the categories of Science, Culture, and World Events/Politics. The timeline allows students to see how the technology and data that scientists have used over the past ... Full description.

In this lesson, students read the original paper written by Henrietta Leavitt in which she compared the apparent brightness and period of Cepheid variable stars. The students prepare graphs from numerical data, just as she did, and compare their data to hers. They then discover that there is a relationship between the period and luminosity of the variable stars she observed, and experience for themselves ... Full description.

The goal of this lesson is for two groups of students to exchange information (e.g., through poster presentations, Podcasts, debates, or PowerPoint presentations) about how two different theories explain a natural phenomenon: Newton's Law of Gravitation and Einstein's General Theory of Relativity. The lesson will also illustrate how the scientific process allows a new, more complete theory to take ... Full description.

This experiment is about contaminiation. Learners will go through a series of steps in which they will test and observe how detergent breaks up contamination in a guided inquiry. Following this they will complete an open inquiry in which they ask questions about variables in washing dishes and design and conduct a test to answer these questions. Includes a teacher's guide and students handouts. Video ... Full description.

This chapter walks users through a technique for documenting change in before-and-after sets of satellite images. The technique can be used for any set of time-series images that are spatially registered to show the exact same area at the same scale. In the chapter, users examine three Landsat images of the Pearl River delta in southeastern China. In these images, users observe changes in land use, ... Full description.
