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:
Period 6
- Do Now– Get out your science notebook and add to the Table of Contents- “Density of Water- p.60” (Left Side). Head page 60 properly with “Density of Water-Model & Conclusion-2/28/17.” Open your science notebook to page 60. Review the procedure handout and have your lab safety checklist ready.
- Investigation– Do different amounts of water have the same density? Complete following procedure to collect data. Answer Analysis Questions 2-7. Tape the Activity handout (procedure & data table) as flip page to p.61. Complete the Lab Safety Checklist “After the Lab is Completed” Questions 1-5.
- Model & Conclusion– Do different amounts of water have the same density? Review data as a class. Set up p.60. Model water molecules in the different volumes of water (100mL, 50mL, & 25 mL) and write conclusion regarding why density of any size sample of water is the same. Trim and tape analysis questions as flip page to p.60.
Periods 2, 4, and 7
- Do Now– Get out your science notebook and open to pages 60-61. Also, take your lab handouts. Start working on your “Voice Finder.” Find and answer question 1, then follow the dashed line to each question to think about and answer each one.
