Mrs. Morrow's Science Unit
Heat & Change
This unit explores the components, and the physical and chemical properties, of matter; discusses the difference between heat and temperature; and then investigates the flow of energy through matter. This information will be studied in Chapter 5 (Investigating Matter) & Chapter 6 (Heat and Matter) of our science textbook.
At the conclusion of this unit students will be able to:
Identify how matter can change and how it is classified
List four physical properties of matter
Explain that a chemical property can only be observed by changing the identity of a substance
Learn that atoms are basic units of matter
Learn that atoms combine to form molecules
List and describe the parts of an atom
Learn that atoms of different elements combine to form compounds
Describe an element
Contrast metals and nonmetals
Explain how elements are organized in the periodic table
Contrast a molecule of an element with a molecule of a compound
Translate a chemical formula
Contrast the properties of a compound with the properties of its elements
Describe three types of solutions and explain how solutions differ from other kinds of mixtures
Contrast solutions and suspensions
Contrast heat and temperature
State the direction of heat flow
Identify conduction as the movement of energy by direct contact between molecules
Identify convection as the transfer of energy when a liquid or gas rises
Identify radiation as energy that can travel through empty space
Describe how molecules react to an increase and decrease in temperature
List three kinds of thermometers that measure most temperatures
Explain how a pyrometer measures temperature
