Evidence - First, we found the size of the diameter of the drop which was about .5mm and that means that the radius is .25 cm. Then we had to calculate the volume by the formula length x width x height and got .035 cm^3. then we found the area and got 1.13cm^3. We eventually got the size of the molecule to be .05 cm.
Explanation - To find the size of the molecule all we had to do was make measurements and plug them into formulas.
Connection - The lab was a great way of getting used to making very precise measurements. Measuring is a great tool in life.In the medical field it is extremely important.
Communication - After completing the lab I'm much better in making precise measurements. I can calculate the volume, thickness, and area of an oil molecule.
Reflection - Almost everybody had different measurements. That can be because of the amount of oil used or how long they waited for it to spread. Also different amounts of powder also play a role. Overall, everyone had used the same formulas and got the right calculations.
