Question

7 apply suppose you want to test the hypothesis that plants grow taller when they receive more sunlight. identify an independent variable and a dependent variable for this investigation.
there is no single correct way to conduct a scientific investigation. some methods include making and testing hypotheses, collecting data, analyzing data and drawing conclusions.
17 a(n) is either supported or unsupported by the results of an investigation.
18 the results of an investigation are the
19 an investigation that has been done by more than one scientist with similar findings has been
20 the most reliable scientific information is published in
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?

Explanation:

1. A hypothesis is a statement that can be supported or not by investigation results.
2. The results of an investigation are data.
3. When multiple scientists get similar findings, the investigation is replicated.
4. The most reliable scientific information is published in peer - reviewed scientific journals as they have a rigorous review process. For the initial question about plant growth, the independent variable is the amount of sunlight plants receive, and the dependent variable is the height of the plants.

Answer:

1. Hypothesis
2. Data
3. Replicated
4. Peer - reviewed scientific journals

Initial question: Independent variable: Amount of sunlight; Dependent variable: Plant height
