Yeast and sugar study

Ask Custom Question

I have just finished doing a science project with my son (8th grade). We tested the best conditions for growing yeast. We used four empty water bottles-one with only yeast and warm water, one with yeast and 1/2 teaspoon sugar and warm water, one with yeast and 1 tablespoon sugar and warm water, and the last bottle was only yeast with no water or sugar as our control. Immediately after adding the ingredients we put balloons over the top of the water bottles and watched them grow (or not). We measured the height of the balloons. We wrote down the results and made nice graphs to go with our data. The sugar really reacted with the yeast.

The last part of our project is to write a small paper (a few paragraphs) that would include the following:

Tell exactly what you did, how you did it, and what you discovered. Be sure to write about your plan and your experiment. Be sure to also include some of the background information you learned.

Could you please helpe me out and answer the questions listed above for our report.

I do not know much about science and I have no idea what we really discovered. I also do not know what our plan or experiment even was.

Thanks
