1. The appearance of the Sun each morning demonstrates four important assumptions scientists
make about the world:
• regularity (it happens over and over again)
• causality (there is a reason for it)
•measurability (it can be measured and verified)
predictability (its recurrence can be anticipated and predicted)
Choose another aspect of the physical world and describe how it fits with these assumptions.
•The changing of the four seasons and the basis that the seasons will forever repeat
2. Why can we never prove that a hypothesis is true?
•In science, a hypothesis is in effect an analogy. You are trying to create a mental model of a
real
world situation and you try to show that evidence from your experimental setup is
consistent.
3. Give an example of a scientific hypothesis. Explain how you would test it, and how it could be
falsified (proved untrue).
