Question

jenny loves to chew gum, but hates losing the flavor. she normally chews juicy fruit, but she wants to know if there is another type of gum that holds the flavor longer. she buys 4 different packs of gum, one of them being her normal juicy fruit. every day after lunch she picks one piece of gum and chews it until it loses flavor. she times how long it takes for the gum to lose flavor, and records the time. she chews the same type of gum every day until she has used up the pack, and finds an average time for how long the flavor lasted. then she starts chewing a new type of gum, and continues until all 4 types have been used.

1. independent variable
2. dependent variable:
3. hypothesis:
4. control group:
5. experimental group:
6. constants:
7. possible threats to accuracy of results?

Explanation:

1. The independent variable is the type of gum as it is the factor being changed.
2. The dependent variable is the time it takes for the gum to lose flavor as it depends on the type of gum.
3. A possible hypothesis could be: A different type of gum will hold flavor longer than Juicy Fruit.
4. The control group is the Juicy Fruit gum since it is the baseline for comparison.
5. The experimental groups are the other 3 types of gum being tested.
6. Constants could include chewing after lunch each day, same person chewing, same method of timing.
7. Possible threats to accuracy could be differences in chewing intensity, diet on different days affecting taste - perception, or inconsistent timing.

Answer:

1. Type of gum
2. Time for gum to lose flavor
3. A different type of gum will hold flavor longer than Juicy Fruit.
4. Juicy Fruit gum
5. The other 3 types of gum
6. Chewing after lunch each day, same person chewing, same method of timing
7. Differences in chewing intensity, diet on different days affecting taste - perception, inconsistent timing
