Part II: Scientific Process:
Use the scenario below to answer questions 1-4:
For their science project, Elena and Glen decided to test the effectiveness of a new fertilizer, Super Grow. The manufacturer of the fertilizer claims Super Grow contains ammonium nitrate (NH
4
N0
3
). Super Grow is supposed to shorten the amount of time required to produce mature, pod-bearing plants from seeds and will increase the number of seeds that germinate. The manufacturer claims the plants treated with Super Grow will be mature in half the normal time and it is environmentally safe. Elena and Glen chose to test Super Grow on pea seeds. They performed the following investigation.
Question: How will adding Super Grow Fertilizer affect the number of pea seeds that germinate?
Hypothesis: _______(see question #1)______________________________________________
Procedure:
1. Put equal amounts of soil mix in containers #1 and #2.
2. Add Super Grow fertilizer to the soil mix in container #2, in a concentration recommended by the manufacturer.
3. Plant 15 pea seeds in each container.
4. Water each container equally every day.
5. Make sure that each container gets the same amount of light and stays at a temperature of 20°C.
6. Record the number of pea seeds that germinate.
_____ 1. Choose the BEST hypothesis to answer the investigative (research) question.
A. If the number of pea seeds is increased then the effect of Super Grow will decrease.
B. If the temperature increases then more pea seeds will germinate.
C. If the amount of light increases then more pea seeds will germinate.
D. If Super Grow Fertilizer is added to the soil then more pea seeds will germinate
_____ 2. Identify the manipulated (independent) variable in this investigation.
A. The amount of soil mixture
B. The number of germinated pea seeds
C. The amount of sunlight
D. The amount of Super Grow added
_____ 3. Identify the responding (dependent) variable in this investigation.
A. The height of the mature pea plants
B. The number of germinated pea seeds
C. The color of the pea plants
D. The amount of Super Grow added
_____ 4. Which of the following is the experimental control condition (control group) for Elena and Glen’s experiment?
A. The number of pea seeds germinated in container #1
B. The number of pea seeds germinated in container #2
C. The height of the germinated pea plants in container #1
D. The height of the germinated pea plants in container #2
E. The amount of sunlight
