Wednesday, 2/15/17- A Day- Outsider’s Day

Core Ideas:

  • Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
  • Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

  1. Do Now– Get out your science notebook and add to the Table of Contents- “Effect of Volume- p.58” (Left Side). Head page 58 properly with “Effect of Volume-Model & Conclusion-2/15/17.” Open your science notebook to page 59. Review the procedure handout and have your lab safety checklist ready.
  2. Investigation– What is the relationship between volume and density for objects of equal mass? On p.58, set up space for model of “Relative size & arrangement of atoms/molecules in plastic & metal cylinders” and Conclusion. Follow procedure to conduct lab investigation. Identify the samples using the densities. Answer question 5. Tape the Activity handout (procedure, data table, question 5) as flip page to p.59. Complete the Lab Safety Checklist “After the Lab is Completed” Questions 1-5.
