an experiment with only two products used which are yest and sugar what are the outcomes? the procedure to conduct this experiment?
To conduct an experiment using only yeast and sugar, you can explore the process of fermentation. The outcome of this experiment would be the production of carbon dioxide gas.
Here's a step-by-step procedure to conduct this experiment:
1. Gather materials:
- Active dry yeast
- Granulated sugar
- Warm water
- Measuring spoons
- Balloon or a rubber glove
- Plastic bottle or jar with a narrow opening
2. Prepare the yeast mixture:
- Start by activating the yeast. Dissolve 1 teaspoon of sugar in ½ cup of warm water (around 100-110°F or 37-43°C).
- Add one packet of active dry yeast (7-9 grams) to the sugar-water mixture.
- Stir gently to dissolve the yeast.
- Allow the mixture to sit undisturbed for about 10 minutes, or until it becomes frothy. This indicates that the yeast is active.
3. Prepare the fermentation setup:
- Take a plastic bottle or jar and place a couple of teaspoons of sugar into it.
- Pour the frothy yeast mixture into the bottle containing the sugar.
- Leave some space at the top of the bottle for the gas to collect.
4. Observe the fermentation:
- Place a balloon or a rubber glove over the opening of the bottle and secure it tightly.
- As the yeast reacts with sugar, it produces carbon dioxide gas as a byproduct of fermentation.
- Over time, the gas will inflate the balloon or cause the glove to inflate.
5. Record and analyze the results:
- Observe the balloon or glove for any changes in size over several hours or days.
- Note the time and record any significant changes in the size of the balloon or glove.
- You can compare different conditions by altering the amount of sugar or yeast used and noting any variations in the speed or extent of the gas production.
Keep in mind that this experiment focuses on the fermentation process and the production of carbon dioxide. It is a straightforward investigation using only yeast and sugar, so the outcomes are limited to the observable gas production.
