This Why Files article investigates the neutrino particle, and why scientists are interested in finding them. The neutrino was 'invented' by a physicist to balance out an equation in the 1950's, and ever since, astronomers and physicists have been looking for these particles as traces to the early universe. The article looks at how neutrinos can be detected in Antarctica, and the universal clues they ... Full description.

This lesson plan is part of the DiscoverySchool.com lesson plan library for grades 9-12. It focuses on nuclear reactions, specifically fusion which creates energy on the Sun. Other types of reactions are radioactive decay and fission. Students look at these different types of reactions and learn about how they happen, and specifics about the Sun such as solar flares, neutrinos, and solar energy. It ... Full description.

This lesson serves as an introduction to color and to both line spectra and continuous spectra, with applications to sunlight. It also explains how a glass prism resolves light into its rainbow components and the difference between spectral colors and the colors perceived by the eye. Students will learn that hot solids (or dense gases) radiate a continuous spectrum, related to their temperature. But ... Full description.

This open-ended laboratory activity is useful in demonstrating how solar wind particles are deflected by the Earth's magnetosphere and how charged particles are aligned within it. After this lesson, students should be able to discuss and describe the components of solar wind particles, explain why the magnetosphere and ionosphere protect the Earth, and explain how moving particles behave (and align) ...

Students will participate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, the students will measure the mass of popcorn kernels. While the mass of the kernels are determined, students will also make predictions of the mass of the kernels after they are popped. After the popcorn is popped, the mass of the popcorn is measured. Data is shared ... Full description.

This activity will help students to have a better understanding of the basic principles used to determine the age of rocks and fossils. It consists of several parts: to have students determine relative age of a geologically complex area, to familiarize students with the concept of half-life in radioactive decay, to have students see that individual runs of statistical processes are less predictable ...

This lesson shows students that age-dating rocks involves counting atoms and comparing the counts. Students use simulated rock samples, which show a highly magnified selection of 128 atoms, each sample with a different proportion of the atoms of two different elements: a parent radioisotope, and its daughter product. By counting the parent radioactive atoms and knowing the half-life of those atoms, ... Full description.
