 What are the differences between matter, mass, weight, and volume?  How can we calculate density?     What are some ways we can identify unknown substances? How do we calculate displacement? How do we read a graduated cylinder? What are the formulas for volume (rectangular solid, cylinder, sphere)? How small is an atom?     How do atoms combine to form molecules? How are atoms and molecules always in motion? What units of measurement do scientists use to collect data? How can we use the measurement-calculation method AND the water displacement method to find the volume of object?

Vocabulary:

You should be able to define the following and apply what they mean. Definitions may come from class notes.
