C Layer- Part I

All assignments in this list are REQUIRED.  Complete each row.

 Assignment Description Point Value Points Earned Initial R Lecture: Ernest Rutherford and Nuclear Radiation Mystery Box Activity 5 5 R Lecture: Atoms & Isotopes Isotopic Pennies Lab 5 10 R Lecture: Types of Radiation Calculating your personal radiation dose Based on your notes, make a list of 10 uses of radiation (good & bad). 5 5 5 R Lecture: Geologic Time Relative Dating Worksheet 5 5 R Activity: Pennium-123 Complete Radiation & Radioactivity Survey 5 5 TOTAL 60

C Layer – Part II

The following assignment choices are optional.  You must complete 19 points worth of these assignments.  These are to be done mostly on your own, as we are limited on class time.

 Assignment Description Point Value Points Earned Initial Based on the lecture notes, create a 10-question quiz and provide an answer key.  Have someone take your quiz without the key, then correct their answers. 10 Take someone else’s 10-question quiz.  Have them correct it.  Each answer is worth ˝ a point. 5 max Use the key terms to create a crossword puzzle.  Exchange with a buddy and correct the puzzle when they are done. 10 Complete someone else’s crossword puzzle.  Have them correct it for you. 5 Using adding machine paper, create a large-scale electromagnetic spectrum.  Be sure to include color and a scale (similar to what a map would have). 5 Complete the Counting Atoms Worksheet. 10

B Layer

Choose ONE of the following to work on outside of class:

 Assignment Description Point Value Points Earned Initial Complete the TOPES writing assignment.  Pick up a copy of the guidelines. 10 Write a song/rap that includes 10 (or more) facts from this unit. Perform your song/rap for three peers and the teacher.  Your song must have a rhythm, words & music that go together, auditory appeal and NO PROFANITY! 10 Create a 6-panel informational brochure about what you’ve learned about radiation.  Include the following: What is radiation? What are some different types of radiation? What are some uses of radiation in our world? Which ones are harmful? 3 graphics (drawings, charts, diagrams, etc.) How do atoms and isotopes fit into the definition of radiation? How is radiation useful in helping to determine the age of Earth? 10

A Layer

 Topic/Question Point Value Points Earned Stamp Should New Mexico have agreed to host the Waste Isolation Pilot Plant (WIPP)? 11 Our lives are filled with objects that are made up of natural resources.  Should we worry about using up our supply of natural resources? 11 Scientists say that the Earth is 4.6 billion years old.  This is a point of controversy between scientists and some religious groups.  Is the evidence that supports the age of the Earth valid? 11 There is a current debate about building a uranium enrichment facility in Eunice, NM.  Supporters say that it will provide economic advantages.  Opponents are concerned about the lack of a disposal plan for radioactive waste.  Should this facility be built in NM? 11
