Earth Science
Physical Science Objectives
After lab activities, homework, and reading assignments in this unit, each
student should be able to:
1. Measure the mass and volume of objects and liquids using correct
metric units.
2. Calculate the density of objects and liquids.
3. Explain how density controls the level at which objects and fluids
float.
4. Explain the relationship between temperature and molecular motion.
5. Explain how compression and decompression affect the temperature
of a substance.
6. Name and describe the parts of an atom.
7. Use Periodic Table of Elements to determine the number of protons,
neutrons, and electrons for any atom of any element.
8. Tell the differences between mixtures, compounds, and elements.
