The following are the experiments listed in Activity 6.2, list down at least 2 quantitative and 2 qualitative variables in these studies. 1. A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly. 2. Green pea plants are given different amounts of water for a three-week period. The first pea plant receives 400 milliliters. The second pea plant receives 200 milliliters. The third pea plant receives 100 milliliters. Fourth pea plant does not receive any extra water, the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. 3. The amount of pollution produced by cars was measured for cars using gasoline containing different amounts of lead. 4. Four groups of rats are first massed and then fed identical diets except for the amount of vitamin A they receive. Each group gets a different amount. After 3 weeks on the diet, the rats' masses are measured again to see if there has been a decrease. 5. An experiment was performed to determine how the number of coffee grounds could affect the taste of the coffee. The same kind of coffee, the same percolator, the same amount and type of water, the same perking time, and the same electrical sources were used.
