Science Buddies: "Ask an Expert"

Can you please provide me the experimental observation and graph for the above mentioned experiment in order to check my results on this experiment ?

Hi Rohit,

We don't have the data for the project ideas, and even if we did, we wouldn't give it out because too many students would cheat and use that data as their own. Though, if you do want to make sure you are on the right track, take a look at the equation for specific rotation (which you should already have in your background research paper). This will give you an idea of what the results should look like if you did the experiment correctly.

I would suggest looking at the following pages in order to analyze your data:

Data Analysis and Graphs: https://www.sciencebuddies.org/science- ... ysis.shtml
Conclusions: https://www.sciencebuddies.org/science- ... ions.shtml

Go back to your background research and make sure you understand all relevant terms and other information. This will help you analyze your results and understand what they mean.

I assume you used this project idea? https://www.sciencebuddies.org/science- ... p073.shtml

If so, look at the "analyzing your data" part to get started. Then take a look at your graphs and look for trends. How does the concentration affect the angle? Why do you think that is? What do you think is happening?

Good luck and let us know if you have other questions.
