Figure 2. Stretch the balloon completely over the bottle's opening, going over all of the bottle's ridges, as shown here.

You could try this science project again but instead of comparing salt, baking soda, and vinegar, you could try comparing different types of sugars or sugars from different sources, such as from various juices. Using the water from the pot, to each bottle add 600 milliliters (mL) (about 2.5 C, or 1/3 full) of warm water, replace the lid, and shake thoroughly to dissolve all of the ingredients. 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! 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).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. Sugar and salt: The salt in this condition will increase the salinity (or amount of salt) that is in the yeasts' environment. Are you tired of carrying separate water bottles and food bowls for your beloved dog during your outdoor adventures? Look no further! We have the perfect solution for you – the Bestie Bottle. Exploratorium Staff. (n.d.). The Science of Bread: Yeast-Air Balloons Activity. The Exploratorium. Retrieved February 27, 2014.

Make a bar graph of the average water displaced for each environmental condition. You can make your graph by hand or use a program like On the x-axis (horizontal axis), put the name of the condition tested, such as "Water only," "Sugar and baking soda," etc. Make a bar for each condition tested. Introducing the Bestie Bottle – The Ultimate Solution for Your Best Friend’s Hydration and Nourishment Needs! Once you have submerged the balloon, carefully lift the pot off of the pan. Pour the water from the pan into the graduated, metric beaker. 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?

Calculate the average water displaced for each condition over the three trials. Record the results in your data table.

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.Add 2 tbsp. of vinegar to bottle #5. How do you think being in an acidic environment will affect yeast fermentation? Using the water from the pot will help you make sure that the water in each bottle is the same temperature.

After 1 hour, look at the balloons. Which ones have become inflated? How big are they compared to each other? Write your observations in your lab notebook. 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 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: 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?In the data table in your lab notebook, record how much water was displaced (how much water is in the beaker) by the balloon, in milliliters. This should be recorded in the column for Trial 1. Then empty the measuring cup. Carefully tie a length of string tightly around the base of each balloon to seal the balloon so that any gas inside cannot escape. When the balloon is tightly sealed, remove it from the bottle top, being very careful not to loosen the string or allow any air to escape from the balloon.
