4 Best Friends Forever Water Bottle, Gift for Bestie, Best Friend Ever, Funny Friend Gift, Water Bottle

Product Information

Water only: This condition will be your negative control because it will not have the food (i.e., sugar) that yeasts need to eat and grow. The yeasts should remain inactive. Figure 1. This image shows what individual yeasts look like using a powerful microscope. These are specifically baker's yeast ( Saccharomyces cerevisiae). 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. 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 R. Fogel. (November 13, 2006).

The Bestie Bottle also keeps hot contents hot for up to 12 hours. So soups, teas, coffee and any other hot liquids will be good to go in your Bestie Bottle. 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). Using the water from the pot will help you make sure that the water in each bottle is the same temperature. 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.

How do you think increasing the salinity will affect the ability of yeasts to carry out fermentation? What about making the environment more basic or more acidic? To measure how well the yeasts carry out fermentation, you will use balloons to trap the CO 2 gas released by the yeasts during fermentation. To measure how much CO 2 is in each balloon you will then submerge each under water and use water displacement to measure how much space each balloon takes up. Which condition(s) will cause the formation of the most CO 2 gas and the most active fermentation? Terms and Concepts 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?Add 2 tbsp. of salt to bottle #3. How do you think increasing the environment's salinity will affect yeast fermentation? 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.

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. After removing each balloon from its bottle, carefully tie a knot at the bottom of each balloon (where the string is) so that you can be sure no air will escape the balloons while you collect your data. This science project is based on a classic science demonstration, nicely described by the Exploratorium, a hands-on science museum in San Francisco: Figure 3. Fill the large pot completely full of water and place it inside of the pan, as shown here.

Another environmental condition that can affect the activity of yeast and the process of fermentation is temperature. Prepare several bottles using the same conditions. Now place each bottle in a different place with a different temperature. After one hour, measure the amount of gas produced and compare. Sugar and vinegar: The vinegar in this condition will decrease the environment's pH, making it more acidic. 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 Exploratorium Staff. (n.d.). The Science of Bread: Yeast-Air Balloons Activity. The Exploratorium. Retrieved February 27, 2014. 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.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. 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!
