Finish Half-Life Analysis
Goal:
Use a spreadsheet to analyze half-lives to answer the following questions:
- The Fermi nuclear power plant melts down. What generation of your descendants will be able to move back to Detroit? Prove it with data from a spreadsheet?
- You're building a sand castle on the shores of Lake Michigan. Digging in the sand, you find the charred wood left from a campfire. Analysis shows that the charring is 93.75% Carbon 12. Approximately how long ago was the campfire made? Who made it?
Steps:
- Create a spreadsheet to calculate half-lives. WE WILL HELP!
- What categories of data do you have?
- What question(s) do you need to be able to answer?
- What math will you need to perform?
- relative cell references
- absolute cell references
- Create a slideshow to present your results. Embed your data from your spreadsheet.
- Include the following slides:
- Title slide (include the names of the people who worked on this)
- The question
- Your data
- Your analysis
- Your conclusion (the answer to the question)
- Each question should be answered in its own slideshow

Assignment 2: Shopping!
Pretend you have been given $300 to spend with only two conditions: you must purchase at least 5 items and you lose any money you don’t spend (so spend as much as possible without going over!). Working by yourself or with a partner, plan how to spend it by creating a spreadsheet that allows you add up the purchase prices and quantities so that you can use as much of your money as possible. Your spreadsheet must:
Hint #1: set up your table(s) and formulas first and then go shopping; it will be easier to stay within your price range.
Hint #2: use colors, borders, and formatting to make it easier to see how your table is organized.
To turn it in:
- Go to View>All Formulas
- Take a screenshot (Part of a page: Crtl + Shift + Switch window
- Import into a Google Slide
- In Google, use shapes and lines to identify a formula, a function, and a range on the screenshot of your spreadsheet.
- Name the slide with your name(s)
- Download as a JPEG.
- Submit the JPEG and your original spreadsheet to Google Classroom.
