2. Make several comparison statements in regards to the caffeine concentrations between types of coffee. For example, how many ounces of Dunkin' Donuts coffee need to be consumed to get the same amount of caffeine that I would get in a Starbucks coffee?

3. How many mg per ounce of caffeine is the whole circle worth? How do you know?

Let's look at how soda and energy drinks compare in caffeine content:

4. Make your own circle model of at least four of the drinks below. The whole circle should represent the same mg of caffeine per ounce as used in the graphic. Make sure to label each graphic and draw in the handle.

5. Is there a drink that has so much caffeine per ounce that it can't be represented with one circle? If so, how can you represent it using this same model? Or how might you manipulate the original model to accommodate this drink? How many ounces of McDonalds Coffee do you need to drink to take in the same amount of caffeine as one serving of this drink?

6. What other type of graph could be used to compare the amount of caffeine per ounce in drinks? Discuss this as a class or in small groups. Select a type of graph and use it to graph the caffeine per ounce of at least six of the drinks mentioned in this activity. Make sure to have a mix of coffee, soda and energy drinks.
