- 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.
- 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.
- Review HW (period 3)– Questions 8 & 9 handout
- 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. and tape analysis questions as flip page to p.60.
- Driving Question Summary Table (except period 3)– Complete the Summary Table on pages 52-53 for the Density of Water Activity.
- Demonstration- Why does a heavier candle float and a lighter piece of candle sink? Record your demonstration observations on page 63.
- Model-Answer Question 4 about density of water, wax, & a candle on the molecular level. Trim and tape the handout to page 62.
