- Draw a picture of the experiment. Label the important variables. Show your procedure.
- Time a few bubbles. Will you need to bin your data?
- You will make a bar graph of the life spans of soap bubbles. Use what you have learned from Question 5 to predict what your bar graph will look like. Make a sketch or write a description for your prediction. Use these questions to help you:
- Will all the bars be about the same height or will some bars be much taller than others?
- Where will the tallest bars be—at the beginning, middle, or end of the graph?
- Will your graph look like one of those shown for humans, robins, or oysters?
- Draw a data table like the one that follows or use the Soap Bubbles Data Table page from the Student Activity Book. Choose time intervals such as 5 or 10 seconds to bin the data. Fill in the first column of the data table with the intervals. Be sure the intervals do not overlap and are the same size.
- Collect and organize the data in your data table.
