Hypothesis: A Testable Prediction
Hypotheses: Cause and Effect?
• Heat will cause metal to expand.Cause: Effect:
• A cart full of bricks is harder to push than an empty cart.
Cause: Effect:
• A ball that is kicked with more force will fly farther.Cause: Effect:
Heat Expansion
Full or empty
Force of kick
How hard it is to push
How far the ball flies
Hypothesis: A testable prediction.
A good hypothesis must:
1. Predict cause and effect.
2. Be written in such a way that it can be tested.
Comparing Good and Bad Hypotheses
Good: The spinning of the earth causes the sun to rise and fall each day.
Bad: The sun will rise tomorrow.
Comparing Good and Bad Hypotheses
1. Good: Being ice cream makes for faster melting, you can test it!.
2. Bad: A question, not a prediction.
3. Bad: No cause and effect.
4. Good: How you behave effects how much you learn, test it out this year!
1. Ice cream melts faster than ice.
2. Will fertilizer make my lawn grow more?
3. Pepsi is better than coke.
4. Working hard, being nice and making good choices will make me a better student.
Re-write Bad Hypotheses
• Will fertilizer make my lawn grow more?
