Bean Passing Lab - Reflection

//** 1. How does the number of beans being passed change as your finger combinations change? **// The number of times the bean was passed changed dramatically for the last three finger combinations. The finger combinations UR1-UR2, UR1-UR3, and UR1-UR5 have similar results of passing the bean between 80-85 times. The finger combination UR2-UR3 had the result of passing the bean about 55 times. The finger combination UR2-UR5 had the result of passing the bean barely 25 times. The last finger combination which was UR3-UR4 had the result of passing the bean a little more than 40 times.

//** 2.What are some conclusions you can develop from looking at this data? **// By looking at this data I can conclude that the results were affected because in some finger combinations we used our thumb(UR1) and sometimes we didn't. The first three finger combinations included using our thumb and the last three finger combinations we didn't use our thumb. Our thumb is an important phalange because it helps us grab or pick up stuff like beans.

Sources of error in this experiment is our rate of passing the bean. The bean might have been passed faster or slower at times. Another error in our experiment is that we might have used our thumb by mistake while passing the bean and that could affect the results.
 * // 3 . What might 2 or 3 sources of error that occurred during this experiment? //**

//** 4. HOW DOES THIS LAB DEMONSTRATE “ADAPTATIONS”? **// This lab shows us that if we use our thumb we can do things faster or more accurately. In this case we were able to pass the bean easier while using our thumb. This adaption helps us do everyday things.
