Be ready to share your statement.

2. This Week’s Goals: Use a formula to calculate density.
Use different lab tools to find an object’s mass, volume, and density.
Explain a density column.
Make predictions if substances will float after analyzing their density values.

3. Density: Solid, Liquid, Gas
Solids are the most dense.
Gases are the least dense.

4. Practice: 22 g; 2 cm³ 50 g; 5 cm³ 8 cm³; 16 g 11 g/cm³ 10 g/cm³
