Suggested answers can be found at the bottom of the NOC ANSWERS​ page.

Activity 1: What causes the Sun to rise?

Picture
Time: 5 min.
Task​: A farmer wakes up every morning to hear his rooster crowing followed shortly by the sunrise. He decides that the rooster's noise must cause the sun to rise.

1. Is he correct?
​2. What kind of logic is he using - inductive or deductive?
3. His daughter wants to scientifically investigate this claim. How might she do it?
4. Challenging​: What does this example suggest about the temporal relationship between cause and effect?
