Step-by-step solution for: Nature of Science Assessment - Multiple Choice Worksheet ...
It looks like you've uploaded a page from a "Nature of Science Assessment" worksheet, which contains multiple-choice questions about scientific methodology. Since I can't view images directly, I’ll help you solve the problems based on the text you've provided.
Here’s the full set of questions and answers with explanations:
---
1. Changeable factor that is being tested in an experiment (what is being changed):
a. Independent variable
b. Dependent variable
c. Controlled variable
✔ Correct answer: a. Independent variable
Explanation: The independent variable is the factor that the experimenter deliberately changes or manipulates to observe its effect. For example, if you're testing how light affects plant growth, the amount of light is the independent variable.
---
2. The variable that we do not change in an experiment:
a. Constant
b. Conclusion
c. Model
✔ Correct answer: a. Constant
Explanation: A constant (or controlled variable) is anything kept the same throughout the experiment so that it doesn’t affect the outcome. For instance, keeping temperature and water amount constant when testing plant growth.
---
3. To draw a conclusion based on what you observe:
a. Experiment
b. Infer
c. Hypothesis
✔ Correct answer: b. Infer
Explanation: Inferring means drawing logical conclusions based on observations. For example, if a plant grows taller under red light, you might infer that red light promotes growth.
---
4. A rule that describes patterns in nature:
a. Scientific method
b. Scientific law
c. Scientific theory
✔ Correct answer: b. Scientific law
Explanation: A scientific law describes a consistent pattern observed in nature (e.g., Newton's Law of Gravity). It does not explain *why* it happens—just *what* happens.
---
5. A collection of ideas, models, and processes that explains natural events:
a. Experiment
b. Science
c. Model
✔ Correct answer: c. Model
Explanation: A model is a representation (conceptual, physical, or mathematical) used to explain or predict natural phenomena. For example, the Bohr model of the atom.
> Note: This question may be ambiguous. If the intent was to ask for a broader explanation of science, “Science” could be tempting—but since it asks for a "collection of ideas," model fits best in context.
---
6. The variable that is changed in an experiment:
a. Constant
b. Independent variable
c. Dependent variable
✔ Correct answer: b. Independent variable
Explanation: Again, this is the variable the experimenter changes. See #1 for more detail.
---
7. A tool or procedure used to test a hypothesis:
a. Experiment
b. System
c. Model
✔ Correct answer: a. Experiment
Explanation: An experiment is a structured process designed to test a hypothesis by manipulating variables and observing outcomes.
---
8. A way to learn about the natural world:
a. Experiment
b. Science
c. System
✔ Correct answer: b. Science
Explanation: Science is the overall process of acquiring knowledge through observation, experimentation, and analysis.
---
9. Variable that changes as a result of a change in the independent variable:
a. Model
b. Dependent variable
c. Constant
✔ Correct answer: b. Dependent variable
Explanation: The dependent variable is what is measured or observed in response to changes in the independent variable. For example, plant height depends on light exposure.
---
10. Factors that can be changed in an experiment:
a. Variable
b. Hypothesis
c. Analysis
✔ Correct answer: a. Variable
Explanation: Variables are factors that can be changed or measured in an experiment. There are three main types: independent, dependent, and controlled.
