NEED HELP I preformed a science project to try and produce weathering on rocks by freezing them and then baking them to see if they would break them into pieces. After preforming the experiment several times I was unable to produce any measurable results. NO change in any of the rocks. My question is how do I show NO change on a data table and graph for a science project board. I need to complete this project soon and do not know what to do if you can not produce measurable results.

What an interesting project! Did you try freezing the rocks with water present? Often it is the expansion of water during freezing that causes rocks to break apart.
If you do not have time to repeat your experiment with and without water, you can still present what you have done. Did you make any measurements (like the length, width, and height of each rock) before and after freezing and baking? If so, you can graph these measurements to show that there was no difference in the measurements before and after your treatment. Something like a grouped bar graph could work well here.
Let me know if this makes sense, and please post again (in this same thread) if you have more questions.
