Life Cycle - Organisms (6A)
- You are going to make a "sorting machine" on paper to organize (classify) your buttons. You may have seen a similar "machine" at a bank or a fair which separates coins poured into the top. This machine organizes coins by size.
- You are going to draw a picture of your machine on the back of this worksheet. It will be a classification tree for buttons.
- First you must make a list of the key characteristics for the buttons. Size might be one. List some other characteristics, but be specific. For example, buttons that are greater than 6 mm but less than or equal than 6 mm. Make sure you are realistic with your buttons. If you don't have any buttons that are less than 6 mm, you should not separate them. You need more than just size.
- Your tree might look like this to start with.
Each time you separate a group of buttons they can be divided into two more groups based on one characteristic (such as "blue and not blue") for the third branch.
CONCLUSIONS: Why is it important to organize information? Does classification help identify an object? How?
- Continue branching until each button (or group of identical buttons) has its own box.
- Your instructor will test your machine with one button to see if it can find its home box when dropped in the top of your machine.
