We need to write a method on this 😭

The first glass which contains cold water has a relatively lower temperature than the other three glasses of solution. With this, the sugar molecules and enzymes possess less kinetic energy and the chance for effective collisions(the sugar binding with the active site of enzymes) is also lower.Therefore, enzymes which are required in aerobic respiration of yeast in glass 1 energy work inefficiently. With less sugar being oxidized, less energy is released for cell division or other metabolic activities per unit time. Therefore, they grow at a slower rate. The second glass of solution actually contains boiling water with its temperature near 100 degrees Celsius. The fact that the yeast does not show obvious growth is due to the denaturing of the enzymes(the changes of the shape of active site, resulting in the active site being not able to bind with sugar to form enzyme-substrate complex). Besides yeast may be killed under such a high temperature. Ultimately, no obvious growth is observed. The third glass of solution is at body temperature(~36 degrees Celsius), which favors the enzymatic reaction(aerobic respiration of yeast). As this temperature is near the optimal temperature, the enzymes can work efficiently, food is oxidized and energy is released at a more rapid rate. Cell division is favored with more energy released. Therefore, the yeast in this glass shows the fastest rate of growth. In the last glass of solution(If I haven't missed any information), the cup is covered with a plastic wrap. The type of respiration carried out by the yeast is mainly anaerobic respiration, in which sugar is oxidized less completely and as such less energy is released. Owing to this, yeast in glass 4 grows slower than that in glass 3 even both glasses of solution are at the same temperature. I hope my answer will be of help. Are these the principles of the experiment? If there are any mistakes, I am looking forward to your advice.

Nope. I’m drawing out diagrams and writing explanations. I’m learning Respiration (Year 8/ 7th Grade Science class) But I am a at home due to COVID restrictions and sent here by my wonderful science teacher :)

Ignore this it’s For school, 1. First take 4 empty glasses and place put an equal amount of sugar (one spoonful) in each one. 2. For one glass pour an amount (just roughly less then half the glass) of cold water 3. Now for the second one, pour in the same amount but with boiled water. 4. After completing 2 & 3, pour in water of body/ blood temperature into the last two remaining glasses (you may test the temperature before hand, by dipping in your finger) 5. Give all the liquids a stir (not too much that the sugar starts dissolving completely) - On a sheet of paper you can label which glass is which. 7. Now add a sachet of yeast to each glass 8. After, Mark the current level of water on the side of the glass (accurately) 9. For the last glass (4th one with blood temperature water) cover it with cling film to restrict the amount of air that the yeast has, to work with. 10. Now set the experiments to set for 5 minutes 11. After the 5 minutes have past, you will notice that the yeast has risen, just like in the way bread does. 12. Now, to keep track of this process you will need to measure the thickness of the foam and record how it changes over time (use a ruler) - writes down the result of 5 minutes on a sheet 13. Wait another 5 minutes, which makes up 10 minutes over all

Yes it may work, though it may take 2-3 days to start observable fermentation. One grain of yeast may contain several thousands of yeast cells so it takes more time to reach that level as using one teaspoon of yeast.

Why did you put a covering over the last one (the one with blood temp water)? Wouldn't that change what happened to that one compared to the other three.

It's meant to decrease the amount of oxygen for the yeast. Which if larger scale, the difference might be more prominent as yeast undergoes cellular respiration using oxygen

what is the yeast rises more in the hot glass than the room temperature glass? does that mean heat is produced during cellular respiration?

Since baking soda is injurious to health, traditional practice of using yeast for bread is more effective in leavening it. But after bread is baked, the yeast dies, leaving multiple holes in the baked dough. Yeast consumes sugar to produce carbon dioxide and ethyl alcohol. This alcohol in trace quantity present in leavened dough evaporates during baking process.
