Please answer the following questions in your comprehension notebook (you do not need to write the paragraph, but please write out A-G.
1.
Scenarios:
1. Compost and Bean Plants
After learning about recycling, members of John’s biology class investigated the effect of various recycled products on plant growth. John’s lab group compared the effect of different-aged grass compost on bean plants. Because decomposition is necessary for release of nutrients, the group hypothesized that older grass compost would produce taller bean plants. Three flats of bean plants (25 plants/flat) were grown for 5 days. The plants were then fertilized as follows: (a) Flat A: 450 g of 3-month-old compost, (b) Flat B: 450 g of 6 month-old compost, and (c) Flat C: 0 g compost. The plants received the same amount of sunlight and water each day. At the end of 30 days the group recorded the height of the plants (cm).
A. Testable question: The effect of various recycled products (compost) on plant growth
B. Hypothesis: If the compost is 6 months old then the plant will grow taller
C. IV: Compost (recycled products)
D. DV: Plant growth
E. Control: Normal soil
F. Constants: Sunlight, amount of compost, same time of plant, water
G. Does the independent variable graph on the o xr y axis? X axis
2. Color of Mashed Potatoes
Gloria wanted to find out if the color of food would affect whether kindergarten children would select it for lunch. She put food coloring into 5 identical bowls of mashed potatoes. The colors were plain, red, green, yellow, and blue. Each child chose a scoop of potatoes of the color of their choice. Gloria did this experiment using 100 students. She recorded the number of students that chose each color.
A. testable question: Does the color of food affect whether the kindergarten children would select for lunch
B. Hypothesis: If the potatoes are blue then the student will select more.
C. IV: Color of food
D. DV: how much the students select
E. Control: The plain potato
F. Constants: Amount of potatoes, same children
G. Does the independent variable graph on the x or y axis? X axis
