Second Grade
S2P1. Students will investigate the properties of
matter and changes that occur in objects.
a. Identify the three common states of matter as solid, liquid, or gas.
b. Investigate changes in objects by tearing, dissolving, melting,
squeezing, etc.
Third Grade
S3P1. Students will investigate how heat is produced
and the effects of heating and cooling, and will understand a change in
temperature indicates a change in heat.
a. Categorize ways to produce heat energy such as burning, rubbing (friction), and mixing one thing with another.
b. Investigate how insulation affects heating and cooling.
d. Use thermometers to measure the changes in temperatures of water
samples (hot, warm, cold) over time.
Fifth Grade
S5P2. Students will explain the difference between a
physical change and a chemical change.
a. Investigate physical changes by separating mixtures and manipulating (cutting, tearing, folding) paper to demonstrate examples of physical change.
b. Recognize that the changes in state of water (water vapor/steam, liquid, ice) are due to temperature differences and are examples of physical change.
c. Investigate the properties of a substance before, during, and after a chemical reaction to find evidence of change.
Eight Grade
S8P1. Students will examine the scientific view of
the nature of matter.
a. Distinguish between atoms and molecules.
b. Describe the difference between pure substances (elements and compounds) and mixtures.
c. Describe the movement of particles in solids, liquids, gases, and plasma states.
d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility).
e. Distinguish between changes in matter as physical (i.e., physical change) or chemical (i.e., development of a gas, formation of precipitate, and change in color).
f. Recognize that there are more than 100 elements and some have similar properties as shown on the Periodic Table of Elements.
g. Identify and demonstrate the Law of Conservation of
Matter.
