Mississippi Science CHE.10.1
The Standard
- CHE.10
- Enrichment: Students will understand that energy is exchanged or transformed in all chemical reactions.
Enrichment: Construct explanations to explain how temperature and heat flow in terms of the motion of molecules (or atoms).

What This Standard Means
What Students Need to Do
- Students explain temperature by describing how fast particles move on average. They explain how energy passes from warmer matter to cooler matter through particle interactions.
What Mastery Looks Like
- A student can draw a heat-flow arrow between objects at different temperatures. They can explain why particles in the cooler object move faster as it warms, while particles in the warmer object slow down.
Common Misconceptions
- Students may treat heat and temperature as the same thing. Some think particles in cold objects stop moving, or that heat flows from cold objects to warm ones.
How to Assess It
- Ask: A room-temperature spoon sits in warm water. Draw the direction of heat flow and explain what happens to particle motion in the spoon and water.

Ways to Teach It
Measure 50 mL of warm water and 50 mL of room-temperature water, mix them, then record the final temperature.
Ask students to explain in three sentences why a cold spoon warms when placed in hot soup.
Give pairs cards showing a warm spoon in cool water and a cold spoon in warm water; have them draw heat-flow arrows.
Have students sketch heat flowing from a warm lunch container to cooler classroom air and label particle motion on each side.
