1 S&S 3.1 Bubble Blowing Fungi Designing your own Investigation GLEs 1.2.1; 1.2.3; 2.1.2; 2.1.3; 2.1.5

2 VOCABULARY ENERGY - the capacity for movement or the ability to cause movement HEAT- energy transferred between substances of different temperatures TEMPERATURE - a measure of the average kinetic energy of the molecules of a substance

3 VOCABULARY Yeast - a single-celled fungi that obtains energy to live and reproduce by digesting sugar

4

5

6 Fermentation - the process of digesting sugar and producing CO 2 Sucrose + WaterEthanol + Carbon dioxide + Energy

7 VOCAB cont. Qualitative Data - general observations that can be best described using words or drawings Quantitative Data - consists of numerical values for quantities being measured

8 INVESTIGATIVE/TESTABLE QUESTION What is the effect of temperature on [manipulated variable] yeast growth? [responding variable]

9 HYPOTHESIS If_______________________________ then____________________________, because__________________________ _________________________________

10 PROCEDURE Work with 1 other person at your Table to design an Investigation to answer the Investigative/Testable Question.

11 HINTS… The more active the Yeast, the more CO 2 produced. The production of CO 2 results in the formation of a layer of foam on top of the yeast solution.

12 HINTS… Some variables to consider: Temperature(s) used Amount of sugar used Length of time allowed for yeast fermentation Method used to measure activity level of yeast

13 Procedure cont. Write the procedures for your Investigation. They must be specific and detailed. Review your procedure with your teacher.
