Students will calculate the energy differences in different energy states of the Bohr atom of Hydrogen. They will then compare these energy levels with observed Hydrogen lines in a laboratory spectrum.

This online article describes hurricanes, how they form, and factors that cause them to intensify and/or weaken.

Students will observe visible spectra of known elements and identify an unknown element or combination of elements by visible spectra.

In this lesson, students will construct a simple pendulum and use it to investigate periodicity. Students will then apply knowledge of periodicity to the orbits of binary star systems.

This activity was developed to get students thinking about the many ways that people use freshwater, and how we can conserve this precious and fundamental natural resource. In this activity, students will watch a short documentary describing issues related to clean water availability, analyze water-use data and start to think about how they consume and can conserve water. This background knowledge will lead to students collecting data about their own water use and finding areas in their lives to conserve water.
