Surface-To-Volume Ratios Predict Which Cells Might Get Rid Of Cells Faster By Diffusion

AIM: The purpose of this experiment was to see if using surface-to-volume ratios can predict which cells might get rid of waste or obtain nutrients faster by diffusion. The hypothesis was if the dimensions of the cell increases and the area of a side get bigger, then the surface-to-volume ratio will increase as well. In this experiment, the independent variable is identified as the dimensions of the cubes (cm) and the dependent variable is the surface-to-volume ratio (cm³). Variables that will remain the same throughout the experiment include the equation used to figure out the surface area for each model, the equation used to find the volume of each model, and the paper, which are what the cubes (cells) are made from.

2. Cut out the flat box with scissors and fold it into a 3-dimensional cube, taping the edges.
3. Now find the surface area of the 1 centimeter cube with the rule: Length x Width x 6.
4. Record the answer onto the data table in the “Surface Area” section with cm² as the unit.
5. Find the volume of the 1 centimeter cube by using the rule: Length x Width x Height.
6. Record the answer onto the “Volume” section with cm³ as the unit.
7. Repeat steps 1-6 for the 2 and 3 centimeters cube dimensions and record the answers on the data table.
8. After all the data have been recorded, form the “Surface Area to Volume Ratio” and reduce if necessary.
