Thursday, 3/2/17- B 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 your Table of Contents- “Sinking & Floating Solids p.63” (Right Side). Head page 63 properly with “Sinking & Floating- Solids-Demonstration-3/1/17.” Complete your Voice Finder from yesterday.
  2. Review HW (period 3)Questions 8 & 9 handout
  3. Model & Conclusion (except period 3)– 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.
  4. Driving Question Summary Table (except period 3)– Complete the Summary Table on pages 52-53 for the Density of Water Activity.
  5. Demonstration- Why does a heavier candle float and a lighter piece of candle sink? Record your demonstration observations on page 63.
  6. Model-Answer Question 4 about density of water, wax, & a candle on the molecular level. Trim and tape the handout to page 62.
