http://img113.imageshack.us/img113/6683/dscf3380tp0.jpg It's really confusing, and the teacher didn't really go too much indepth on how to work this, so far i plotted the data, i used interpolation to estimate the data for 0.03 cm and 0.06 cm,

how do i write the proportionality statement? it just starts getting really confusing and the work that I did is just a guess, can someone PLS PLS PLS help me!

Hi Lawcheehung! Welcome to PF!

Sorry, but you photos are blurred, and hurting my eyes.

Can you type the question, please?

I understand that analyzing experimental data can be challenging, but it is an important part of the scientific process. Looking at the provided images, it seems that you have accurately plotted the data and used interpolation to estimate the data for 0.03 cm and 0.06 cm. This is a good start!

To write the proportionality statement, you will need to look at the relationship between the independent variable (thickness of the aluminum foil) and the dependent variable (current). From the graph, it appears that as the thickness of the foil decreases, the current increases. This suggests an inverse relationship between the two variables.

A possible proportionality statement could be: "The current is inversely proportional to the thickness of the aluminum foil." This means that as one variable increases, the other decreases in a predictable manner. You could also add in a constant of proportionality, if you are able to determine it from the data.

It is also important to note any trends or patterns in the data. For example, in this experiment, the current seems to increase at a decreasing rate as the thickness of the foil decreases. This could be due to factors such as resistance in the circuit or limitations in the measurement equipment.

In conclusion, your work so far is a good start, but it would be helpful to have more information about the experiment and the specific instructions for the analysis. It may be helpful to consult with your teacher or a peer to clarify any confusion and ensure that you are on the right track. Keep in mind that as a scientist, it is important to carefully analyze and interpret your data in order to draw accurate conclusions.
