# Near-Earth supernova - Wikipedia

In this activity, the behavioral objectives are: (1) the students will be able to estimate the composition of elements within a given population, and (2) the students should be able to determine what object the population represents based on the composition of the given population. This activity is allotted one class period for completion and discussion.

## the term supernova nucleosynthesis is ..

### The supernova is pointed by the arrow

The behavioral objectives for this activity include: (1) students will learn how white light can be separated into its various colors, (2) students will learn the mathematical relationships between wavelength, frequency, and energy of light, (3) students will learn how to solve for a variable by rearranging an algebraic equation, and (4) students will learn about the nature of light and the electromagnetic spectrum. After reading the article entitled "What is Electromagnetic Radiation?" the students will be able to use the following equations: c = Λf and E = hf to complete the worksheet entitled "Calculation Investigation". Using the aforementioned equations, the students will be able to solve for different variables with the proper units by rearranging the algebraic equations. The time allocated for this activity is one class period.

### Scientists call this supernova nucleosynthesis.

The main activity for this unit will be for each cooperative learning group to prepare and present a fifteen minute power point presentation on a different aspect of the origin of the elements. After briefly presenting the basic foundations of the Big Bang theory and nucleosynthesis, each group will be assigned one of the following topics for their presentation: history of the Big Bang theory, stellar evolution, Big Bang nucleosynthesis, stellar nucleosynthesis, supernova nucleosynthesis, nuclear fusion reactions, and neutron capture reactions. The students will be escorted to the high school library where they will research their topics for two days using both written and electronic resources. The following two days each group will prepare their power point presentation. Presentation and discussion of their work will take place over the last few days of this unit.
