Name:______________________________Period:________Date:__________ One bean, two beans, three beans, four…. Scientists classify organisms into specific categories to help organize our world. Flowers are just one example of how we organize our world. For example, is a daisy the same as a rose? How do you know? 1. Today you are going to use your powers of observation to classify a mix of beans/peas into distinct groups. First though, let’s review the seven levels of classification. Most General Category Most Specific Category 2. In front of you is a mixture of dry beans/peas. Pour the beans out onto the triangle of your pie chart marked “mix”. Name:______________________________Period:________Date:__________ 3. Examine your beans/peas and separate your mix into two groups. Place one group on the “Group I” triangle. Place the second group on the “Group II” triangle on your white paper. 4. What is different about Group I and Group II? 5. Within the Group I triangle, further separate your beans/peas. What is different about your new groups? 6. How many different groups did you make for group I? 7. Within the Group II triangle, further separate your beans/peas. What is different about your new groups? 8. How many different new groups did you make? 9. How does this exercise relate to the classification system? 10. Use the dichotomous key to determine the name of the beans you have separated.
