Questions
1. Did this series of questions correctly
organize each organism? Why or why not?
2. What additional questions would you
ask to further categorize the items within
the kingdoms (Hint: think about other organisms in each of the kingdoms and
what makes them different than the examples used here)?
3.
What
questions would you have asked instead of the ones that you answered above when
classifying the organisms?
