investigate and predict cause-and-effect relationships in science

Texas Essential Knowledge and Skills for Science

Teacher's field guide

What Students Need to Do: Students change one part of a simple setup and observe what happens. They predict an effect, test it, and use observations to explain the relationship.
What Mastery Looks Like: A student can name the cause and the effect in an investigation. The student makes a reasonable prediction and supports it with observations from the test.
Common Misconceptions: Students may think any event that happens first caused the next event. They may treat predictions as random guesses or change several parts of a setup at once.
How to Assess It: Show a toy car beside a low ramp and a steep ramp. Ask students to predict which ramp makes the car travel farther and explain why.

Lesson moves

Roll the same toy car down ramps at two heights, measure each distance, and record how ramp height changes travel.
Discuss: “What might happen to a plant kept without light, and what evidence supports your prediction?”
Match cause cards to effect cards, then earn a point by explaining each pair with a complete sentence.
Compare photos of a street before and after heavy rain, then identify what caused each change.
