Sugar: This condition will be your positive control because it will have the sugar that yeasts need to eat and carry out fermentation. Adjust the temperature of the hot water coming from the tap until it is almost too hot to hold your hands under. Use this temperature water to fill the pot. Using the water from the pot will help you make sure that the water in each bottle is the same temperature.

Repeat steps 16.a. to 16.e. until you have done the water displacement test for each of the five balloons. Sugar and salt: The salt in this condition will increase the salinity (or amount of salt) that is in the yeasts' environment. Calculate the average water displaced for each condition over the three trials. Record the results in your data table. In what environment(s) did the yeast produce the most CO 2 gas? What does this say about the ideal conditions needed for yeast fermentation to take place? Now you are ready to measure the amount of CO 2 gas inside each balloon with a water displacement test. To do this, do the following:Not only does the Bestie Bottle offer practicality, but it also promotes sustainability. By investing in this eco-friendly water bottle, you’re reducing single-use plastic waste that harms our planet. Join us in taking small steps towards a greener future! Introducing the Bestie Bottle – The Ultimate Solution for Your Best Friend’s Hydration and Nourishment Needs! Sugar and baking soda: The baking soda in this condition will increase the environment's pH, making it more basic.

In what environment(s) did the yeast produce the least CO 2? What does this tell you about the conditions that yeast do not prefer for carrying out fermentation? Plastic 2 L bottles (5). If you do not want to clean out and reuse the same bottles after each trial, you will need 10 additional bottles.So why wait? Say goodbye to cumbersome containers and hello to simplicity with the Bestie Bottle. Treat yourself and your bestie to the best bottle out! Repeat steps 3–17 two more times so that you have done a total of three trials. Each time be sure to record your results in your data table for the correct trial number.

Table 1. In your lab notebook, make a data table like this one to record your observations and results in. You will be recording how much water is displaced in milliliters (mL). With its durable stainless steel construction, the Bestie Bottle ensures optimal insulation, keeping your dog’s water cool and refreshing even during scorching summer days. Additionally, it guarantees a safe and healthy mealtime experience as it is free from harmful chemicals commonly found in plastic alternatives.

Latex balloons, around 9 to 12 inches inflated size (5). These may be found at discount and/or party-supply stores, or through online suppliers such as Take one of the balloons and slowly dunk it into the large pot of water. Water should spill out and go into the pan that the large pot is sitting in. Dunk the balloon until it is completely submerged. If the pan becomes full of water before the balloon is completely submerged, go on to step 16.d. and then repeat steps 16.b. to 16.d. until you can completely submerge the balloon.
