Question

science scenario 2-
your little brother really likes to eat tomatoes. you decide to grow your own for him and want to start with planting cherry tomato seeds. you want to grow your plants as fast as possible, so you are going to test different amounts of fertilizer and water mixture.
you decide to measure the amount of growth after 8 weeks. you test 4 groups of plants- group #1 gets just water, group #2 gets 10% fertilizer water, group #3 gets 50% fertilizer water and group #4 gets 75% fertilizer water.
you put the data you gather into a chart:

group	week 1	week 2	week 3	week 4	week 5	week 6	week 7	week 8
2	1\	2.5\	3.5\	4\	4.5\	5.5\	6\	7\
3	1\	3\	4.5\	6\	7.5\	8\	9\	9.5\
4	1\	3\	5\	7\	8.5\	9.5\	10\	10.5\

questions-

1. what would be a good question for this investigation?
2. what would be a possible hypothesis to the question?
3. what is the independent variable?
4. what is the dependent variable?
5. what type of data did you collect (quantitative or qualitative)?
6. what is the conclusion? (include evidence to prove it)

Explanation:

1. A good question could investigate the impact of different fertilizer - water mixtures on cherry tomato plant growth. For example, "How does the percentage of fertilizer in the water affect the growth of cherry tomato plants over 8 weeks?"
2. A possible hypothesis is that as the percentage of fertilizer in the water increases, the growth of cherry tomato plants will increase. This is based on the common understanding that fertilizers provide nutrients for plant growth.
3. The independent variable is the percentage of fertilizer in the water for each group of plants (0% for Group 1, 10% for Group 2, 50% for Group 3, 75% for Group 4). It is the variable that the experimenter changes.
4. The dependent variable is the amount of growth of the cherry tomato plants, measured in inches. It is the variable that is affected by the independent variable.
5. The data collected is quantitative as it is numerical (the growth in inches).
6. Conclusion: The higher the percentage of fertilizer in the water, the greater the growth of the cherry tomato plants. Evidence: Group 4 (75% fertilizer water) had the most growth (10.5 inches at week 8), followed by Group 3 (50% fertilizer water) with 9.5 inches at week 8, then Group 2 (10% fertilizer water) with 7 inches at week 8, and Group 1 (just water) with 8 inches at week 8.

Answer:

1. How does the percentage of fertilizer in the water affect the growth of cherry tomato plants over 8 weeks?
2. As the percentage of fertilizer in the water increases, the growth of cherry tomato plants will increase.
3. The percentage of fertilizer in the water.
4. The amount of growth of the cherry tomato plants.
5. Quantitative.
6. The higher the percentage of fertilizer in the water, the greater the growth of the cherry tomato plants. Evidence: Group 4 (75% fertilizer water) had the most growth (10.5 inches at week 8), followed by Group 3 (50% fertilizer water) with 9.5 inches at week 8, then Group 2 (10% fertilizer water) with 7 inches at week 8, and Group 1 (just water) with 8 inches at week 8.
