Reflection (2)

=** After embedding your graph into your wikispace, answer the following questions: **= = = =** How does the number of beans being passed change as your finger combinations change? The number of beans being passed changed because the finger combination changed. Depending on which fingers we were asked to use, the difficulty to pass the bean changed. For example, when Maryam and I used the fingers UR1 and UR2, we were able to pass the bean 86 times because it was our pointer finger and our thumb. But when we used the fingers UR2 and UR5, we were only able to pass the bean 23 times because it was our pinky and our pointy. We were able to pass the bean faster using our pointer and thumb because it was easier to hold the bean. **= =**What are some conclusions you can develop from looking at this data? **= =** When we used our opposable thumbs, we were able to pass the bean more because it was easier to hold the bean. When we used our pointer and middle finger, it was harder to hold the bean. Maryam and I tried different techniques to grab the bean. **= = = =**What might 2 or 3 sources of error that occurred during this experiment? **= =** Some errors that might have occurred in this experiment might be that we switched fingers when passing the bean, dropping the bean, and maybe forgetting the time limit. **= = = =** HOW DOES THIS LAB DEMONSTRATE “ADAPTATIONS”? **= = = =** This lab shows us how opposable thumbs are adaptations. It showed us that without opposable thumbs, we wouldn't be able to do the normal life things we do now as easy as we would if we dint have them. **=
