critical thinking
use the table below to answer the following questions.
plant amount of water given amount of fertilizer given height
1 10 ml none 6 cm
2 20 ml 5 g 8 cm
3 30 ml 10 g 7 cm
4 40 ml 15 g 12 cm
10 evaluate the table above shows the data collected during an experiment about plant height. based on the data collected, is this a controlled experiment? why or why not?
11 describe how would you experiment to find out how much water this plant type needs for optimal growth?
12 recommend write a checklist with at least three entries for how you can evaluate whether scientific information is reliable.

# Brief Explanations:
A controlled experiment has only one independent variable while keeping others constant. Here, both water and fertilizer amounts change, so multiple variables are altered simultaneously.
# Answer:
No, this is not a controlled experiment because both the amount of water and the amount of fertilizer are being changed at the same time, so it's impossible to determine which variable (or combination of variables) is affecting the plant height.

# Brief Explanations:
Keep fertilizer amount and other factors constant. Vary water amounts and measure plant growth over time.
# Answer:
1. Select a group of identical plants of the same type.
2. Keep the amount of fertilizer, sunlight exposure, soil type, and temperature the same for all plants.
3. Give different amounts of water (e.g., 10 mL, 20 mL, 30 mL, etc.) to each plant in the group.
4. Measure the height or other growth - related metrics (such as number of leaves) of the plants at regular intervals (e.g., daily or weekly) and record the data.
5. Analyze the data to determine which water amount leads to the best growth.

### 12
# Brief Explanations:
Consider source credibility, experimental design, and reproducibility.
# Answer:
1. Check the source: Determine if the source of the scientific information is a reputable institution, scientist, or peer - reviewed journal.
2. Examine the experimental design: Look for proper controls, a sufficient sample size, and appropriate variable manipulation in the experiments that generated the information.
3. Consider reproducibility: See if the experiments or studies can be replicated by other researchers to obtain similar results.
