Research

35. Find out whether you have a smoke detector in your home, where it is located, if it has ever gone off, whether there have been any false alarms, and if so, what caused them. Check with an adult to find out whether the battery is checked regularly. If you do not have a smoke detector, go to a friend's house and find out the answer to these questions. 5 pts

36. Research isotopes and how they are used for medical purposes. Oral defense 15 pts

37. Research the contributions of the following scientists: Henri Becquerel and Marie and Pierre Curie. In relation to the contributions they made to the discovery and understanding of radioactivity. Your research must include a bibliography of at least 3 sources and be at least 2 pages in length. Papers may be typed or written. 15 pts

39. Find out how many different forms a hydrogen atom exists in (in reference to isotopes) oral defense 15 pts

Various/Miscellaneous

40. PAGE 39/ Figures 2-6à How did Crookes know that the beam was not light? Figures 2-7à How are television tubes and computer display screens related to the cathode-ray tube that Crookes used? oral defense 5 pts

41. The Roman poet Lucretius wrote these words about atoms in his poem De Rerum Nature (On

The Nature of Things). "Their nature lies beyond our range of sense. Far, far beyond. Think about

what he meant and write a paragraph about his idea of the nature of atoms. oral defense 10 pts

42. Use the phrase radioactive decay and the word transmutation in a labeled illustration of a decay process. Examples could be in the for m of a comic strip 10 pts

43. Using page 47 of your textbook, count the number of nuclear particles in the diagrams of the three carbon atoms. How are the carbon atoms the same? How are they different? Oral defense 5 pts.

49. Problem solving on page 53. Design a container to transport radioactive waste. A whole raw egg will represent the waste. Your container will be dropped from a height of approximately 7-10 meters onto a hard surface. Your container will also be struck by a bottle of sand suspended from a door frame.

Along with your container, research how radioactive waste containers operate. How much impact Can containers which contain nuclear waste take? What are these containers made of? Why do these containers need to be made out of such a substance? 10 pts

50. Write a report comparing the scientific views from the past about the nature of matter i.e.. Atomic Theory. Your report should span from the Greeks to modern wave theory 10 pts
