Step-by-step solution for: Scientific Method Worksheet and Answers (Word) by Woods Wacky Science
It looks like you've uploaded a document titled "Scientific Method / Experimental Design" that contains a set of multiple-choice questions related to the scientific method and experimental design. Since I can't view images directly, I'll help you solve the problems based on the text you provided.
Here is the content of the worksheet with explanations and correct answers:
---
#### Directions: Use the terms in the following multiple-choice question to write the correct answer.
1. The step in the hypothesis model that comes after forming a hypothesis is:
- a. conclusion
- b. experiment
- c. observation
- d. theory
✔ Correct Answer: b. experiment
👉 After forming a hypothesis, the next step is to test it through an experiment.
---
2. When a scientist conducts an experiment, the variable that is changed is called the:
- a. control
- b. dependent variable
- c. independent variable
- d. constant
✔ Correct Answer: c. independent variable
👉 The independent variable is what the experimenter deliberately changes or manipulates.
---
3. In an experiment, the variable that is measured or observed is called the:
- a. control
- b. dependent variable
- c. independent variable
- d. constant
✔ Correct Answer: b. dependent variable
👉 This is the outcome that responds to changes in the independent variable.
---
4. A group of organisms that are not exposed to the experimental condition is called the:
- a. control group
- b. experimental group
- c. independent variable
- d. dependent variable
✔ Correct Answer: a. control group
👉 The control group helps provide a baseline for comparison by not receiving the experimental treatment.
---
5. A statement that explains why something happens is called a(n):
- a. theory
- b. hypothesis
- c. experiment
- d. observation
✔ Correct Answer: a. theory
👉 A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence.
---
6. A possible explanation for a phenomenon that can be tested is called a(n):
- a. theory
- b. hypothesis
- c. observation
- d. experiment
✔ Correct Answer: b. hypothesis
👉 A hypothesis is a testable prediction made before conducting an experiment.
---
7. Information gathered from observing a phenomenon is called:
- a. data
- b. theory
- c. hypothesis
- d. experiment
✔ Correct Answer: a. data
👉 Data refers to the raw facts and measurements collected during observations or experiments.
---
8. When designing an experiment, scientists must ensure that only one variable is changed at a time. This is known as:
- a. control of variables
- b. replication
- c. randomization
- d. correlation
✔ Correct Answer: a. control of variables
👉 This ensures that any observed effects are due to the independent variable and not other factors.
---
9. In an experiment, which of the following is NOT a variable?
- a. independent variable
- b. dependent variable
- c. control
- d. constant
✔ Correct Answer: d. constant
👉 Constants are kept the same throughout the experiment; they are not variables.
---
10. Which of the following best describes a controlled experiment?
- a. An experiment where all variables are changed
- b. An experiment where only one variable is changed
- c. An experiment where no variables are changed
- d. An experiment where the results are unpredictable
✔ Correct Answer: b. An experiment where only one variable is changed
👉 This allows scientists to determine cause-and-effect relationships.
---
11. What is the purpose of repeating an experiment multiple times?
- a. To increase the number of variables
- b. To make the results more reliable
- c. To reduce the need for controls
- d. To avoid using a hypothesis
✔ Correct Answer: b. To make the results more reliable
👉 Repetition helps confirm results and reduces the impact of chance or error.
---
12. In an experiment, if the independent variable is temperature and the dependent variable is plant growth, what would be a good hypothesis?
- a. If temperature increases, then plant growth will increase.
- b. If plant growth increases, then temperature will increase.
- c. Temperature does not affect plant growth.
- d. Plant growth is unrelated to temperature.
✔ Correct Answer: a. If temperature increases, then plant growth will increase.
👉 This is a clear, testable hypothesis stating a cause-and-effect relationship.
---
13. Which of the following is NOT a step in the scientific method?
- a. Make a hypothesis
- b. Conduct an experiment
- c. Draw a conclusion
- d. Create a law
✔ Correct Answer: d. Create a law
👉 While laws may result from repeated observations, "creating a law" is not a standard step in the scientific method. Steps typically include: observe, ask a question, form a hypothesis, experiment, analyze data, draw conclusions.
---
14. If a scientist wants to test whether fertilizer affects plant growth, what should the independent variable be?
- a. Type of plant
- b. Amount of sunlight
- c. Amount of fertilizer
- d. Soil type
✔ Correct Answer: c. Amount of fertilizer
👉 This is the variable being manipulated to see its effect on plant growth.
---
15. Which of the following is an example of a dependent variable?
- a. Time of day
- b. Type of soil
- c. Height of a plant
- d. Temperature of room
✔ Correct Answer: c. Height of a plant
👉 This is what is being measured in response to changes in other variables (e.g., fertilizer).
