Intro to density day 1
- 1. You will Need: 1)Pencil, Colored Pencil, Highlighters 2) SAS Curriculum + Cornell Notes – Due Now 3)Log #2 – Update- Managers login
- 2. A substance’s density is the measure of the mass of material within a certain volume. (amnt of space taken up) The mass (amount of particles) is affected by how tightly packed the molecules are within the space.
- 3. Sample Chemical Symbol Density g/cm3 Physical Attribute Lead Pb 11.3 Heaviest Mass Copper Cu 8.9 Orange Iron Fe 7.9 Magnetic/Rusts Brass Cu & Zn 8.6 Yellow Aluminum Al 2.7 Lightest Mass Zinc Zn 7.1 Dull Gray You will need this chart to ID substances.
- 4. Substance Mass (g) Volume (cm3 ) Density (g/cm3 ) 4. Cube 1= _________ 5. Cube 2 = _________ 6. Cube 3 = _________ 7. Cube 4 = _________ 8. Cube 5 = _________ 9. Cube 6 = _________
- 5. Sample Chemical Symbol Density g/cm3 Physical Attribute Lead Pb 11.3 Heaviest Mass Copper Cu 8.9 Orange Iron Fe 7.9 Magnetic/Rusts Brass Cu & Zn 8.6 Yellow Aluminum Al 2.7 Lightest Mass Zinc Zn 7.1 Dull Gray Copy chart onto Cornell Notes
- 6. 1. THINK about the concepts of VOLUME, DENSITY and MASS. 2. Circle same or different. 3. Explain WHY.
- 7. 1. THINK about the concepts of VOLUME, DENSITY and MASS. 2. Circle same or different. 3. Explain WHY. #5. Objects A and B have the same or different densities because Iron Iron A B They are the same substance & the particles are packed the same way
