- 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 Liquids p.65” (Right Side). Head page 65 properly with “Sinking & Floating Liquids-Demonstration-3/6/17.”
- Demonstration (Period 4)– Why does a heavier candle float and a lighter piece of candle sink? Record your demonstration observations on page 63.
- Model (Periods 2, 6, & 7)–Answer Question 4 about density of water, wax, & a candle on the molecular level. Trim and tape the handout to page 62.
- Demonstration- Do all liquids have the same density? Record your demonstration observations of the candles floating on two different liquids and the density column on page 65. Tape Questions 3 & 5 to page 65.
- Model- Answer Question 6 about water alcohol and oil on the molecular level. trim and tape the handout to page 64.
Period 3- Take It Further Questions 7-10 handout
