9. Theory Hypothesis Law Question

10. Question-- Science attempts to answer questions about the natural world. It does not answer questions about right, wrong, good, or bad.

11. People throughout the ages have wondered about the Earth that we live on.

12. Theory Hypothesis Law Question

13. Question-- Science attempts to answer questions about the natural world. It does not answer questions about right, wrong, good, or bad. Hypothesis— A reasonable and educated possible answer based on what you know.

14. An ancient Greek philosopher named Eratosthenes proved that the Earth was round in 200 B.C. He noticed that at noon on the summer solstice, in his city, the sun was directly overhead. In Alexandria, at the same time on the same day, the sun was at a 7 degree angle. If the Earth was flat, this would not be. He also used this to calculate the circumference of the Earth with great accuracy!

16. Despite Eratosthenes’ discoveries, many people throughout Europe believed that the Earth was flat. It looked flat, so it must be flat!

17. Theory Hypothesis Law Question

18. Question-- Science attempts to answer questions about the natural world. It does not answer questions about right, wrong, good, or bad. Theory— An attempt to explain a pattern observed repeatedly in the natural world. Hypothesis— A reasonable and educated possible answer based on what you know.

19. Some people also noticed that during a lunar eclipse, when the Earth’s shadow covered the moon, the shadow was round. This was further evidence that pointed to the Earth being round. Some people were still not convinced! It still looked flat!

20. Other people saw that the stars in the sky were different in different locations. If the Earth were flat, this would not be the case! Yet, most people still maintained that the Earth was flat! It looked flat!

21. Theory Hypothesis Law Question

22. Question-- Science attempts to answer questions about the natural world. It does not answer questions about right, wrong, good, or bad. Law— A rule that describes a pattern in nature that has been observed repeatedly. It stands until someone makes observations that do not follow the law. Theory— An attempt to explain a pattern observed repeatedly in the natural world. Hypothesis— A reasonable and educated possible answer based on what you know.

23. _________– Science attempts to _______ questions about the __________. It does _____ answer questions about right, _____, good, or _______. _____— A _____ that describes a _________ in _______ that has been observed repeatedly. It stands ______ someone makes observations that do ______ follow the ____. ________— An attempt to ______ a ______ observed __________ in the natural world. __________— A __________ and _________ possible answer based on what you ________.

24. Eventually, sailors like Christopher Columbus sailed past the horizon and did not fall off the Earth. This convinced almost everyone that the Earth was indeed round.

25. After years of proof and support with no one being able to disprove the theory, the theory of the Earth being round became a In modern times, we have sent astronauts into space who have taken pictures of the Earth. It is indeed round.

26. There are people in recent history who still believe that the Earth is flat. Since they are unable to disprove the Law, it remains. If they discover evidence that proves the Earth is not round, then the Law of the Earth being round will drop back to the level of a theory.

27. Heliocentrism (The Earth revolves around the sun.) Hypothesis, Theory, or Law?

28. Evolution Hypothesis, Theory, or Law?

29. Gravity Hypothesis, Theory, or Law?

30. Students perform better on tests while chewing gum. Hypothesis, Theory, or Law?

31. How can you observe liquids passing through a cell membrane?

32. How does air resistance affect the velocity of falling objects?

33. Is the ability to roll your tongue dominate or recessive?

34. Can the stem cell of a plant reproduce root cells for a new plant?

35. Liquids will pass into the cell through the cell membrane.

36. Air resistance will slowdown all falling objects, but gravity will continue to pull them down.

37. The ability to roll your tongue will show up as a recessive trait.

38. Stem cells from the plant will produce root cells for a new plant 80% of the time.

39. The water in the vinegar passes through the cell membrane. The particles inside the egg are too large to move out through the membrane.

40. Air resistance slows down all falling objects. Lightweight objects with more exposed surface areas are more greatly affected.

41. The ability to roll the tongue is a dominate trait. If both parents have the recessive trait, their child will not be able to roll their tongue.

42. The cells in a plant have the necessary material to become any other type of plant cell.
