Chemistry vs. Astronomy

8th Grade

Content Area & Topic: Chemistry and Astronomy

Lesson Overview: How were planets and stars discovered? When did chemistry evolve? Questions are always being asked about when something was discovered or how it works. Here the timeline can help to show the different eras of when breakthroughs were made in chemistry and astronomy. While looking at the timeline one might see how astronomy and chemistry were similar and different in each era.

Flame Test

8th Grade

Content Area & Topic: Astronomy, Chemistry, and Physics

Lesson Overview: Ever wonder what makes the colors of the fireworks? When scientists get samples of soil from planets or satellites (moons) how can they see what metals are there? Different metals give off different colors of light. When a solution of a metal is used on a flame test, a color will be given off to tell which metal is in the solution.

Iowa Core Statements:

  • Understand and apply knowledge of the components of our solar system.
  • Understand and apply knowledge of forms of energy and energy transfer.

Content Objectives:

  • Recognize natural structures in the solar system.
  • Recognize that energy is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical.

Biopolymer and Nylon 6, 10 Synthesis

8th Grade

Content Area & Topic: Engineering and Chemistry

Lesson Overview: This lesson is designed to fit into the energy unit, talking about energy transfer from thermal to chemical and such. The polymerization process is an easy way to see how chemical energy can be stored. The demonstration provides a way to bring a laboratory style demonstration to the classroom while providing content rich material for discussion on energy as well as polymers, a field few middle school students know about.

Iowa Core Statements:

  • Understand and apply knowledge of forms of energy and energy transfer.

Content Objectives:

  • Recognize examples of energy conversions in real situations.
  • Summarize and apply the law of conservation of energy.
  • Evaluate the advantages and disadvantages of various energy resources.
  • Distinguish between heat and temperature.
  • Explain how thermal energy is transferred.
