Question

1. what is the responding variable or the variable that is affected and measured?(dn c1 l2 slide 11, 18 - 19, 21)
2. why is communicating such an important step in the scientific process? give two ways a scientist communicates (p. 29)
3. a scientist wants to conduct a controlled experiment to see if the amount of water affects the height of a plants growth. identify: (dn c1.l2, 11, 18 - 19, 25 - 31)

what is the independent variable?
what is the dependent variable?
what are two constants?

1. what is the purpose for scientific inquiry or what does it accomplish? (text page 23)
2. what is the difference between observation and inference? come up with an example of each. (dn c1.l1 slides 8 - 16)

Explanation:

1. The responding variable is the dependent variable. It is what is being measured and affected by other factors.
2. Communication is important in the scientific process as it allows sharing of results for verification and collaboration. Scientists communicate through publishing papers and presenting at conferences.
3. The independent variable is the amount of water as it is being changed. The dependent variable is the height of the plant's growth as it is being measured. Two constants could be the type of plant and the amount of sunlight (to keep other factors the same).
4. The purpose of scientific inquiry is to gain knowledge, understand natural phenomena, and develop explanations through evidence - based methods.
5. Observation is gathering information using senses. For example, seeing that a flower is red. Inference is a conclusion based on observations, like inferring that a flower is pollinated because there are bees around it.

Answer:

1. Dependent variable
2. Allows sharing of results for verification and collaboration; publishing papers, presenting at conferences
3. Independent variable: Amount of water; Dependent variable: Height of plant's growth; Two constants: Type of plant, amount of sunlight
4. To gain knowledge, understand natural phenomena, and develop evidence - based explanations
5. Observation: Gathering information with senses, e.g., seeing a flower is red. Inference: Conclusion based on observations, e.g., inferring a flower is pollinated as there are bees around it.
