Step-by-step solution for: Scientific Method Review Worksheet by Elly Thorsen worksheets library
Thank you for uploading the image. It’s a Scientific Method Test Review Worksheet designed to help students review key concepts in experimental design, variables, and data analysis.
Since I can’t see the actual image (as per my current capabilities), I’ll provide a complete, detailed solution based on the *text* you’ve shared — which appears to be a transcription of the worksheet. I’ll answer each question thoroughly, as if I were completing the worksheet for a student.

## ✔ Scientific Method Test Review Worksheet – Complete Answers
---
1. Give three examples of qualitative data describing where you are.
> Qualitative data describes qualities or characteristics that cannot be measured numerically.
>
> - The room is brightly lit with natural sunlight.
> - There’s a strong smell of coffee in the air.
> - The walls are painted a soft blue color.
*(Other acceptable answers: “It’s quiet here,” “The chair is comfortable,” “There’s a picture of mountains on the wall.”)*
---
2. Give two examples of quantitative data describing where you are.
> Quantitative data involves numbers and measurements.
>
> - The room temperature is 72°F.
> - There are 4 windows in this room.
*(Other acceptable answers: “I am sitting 3 feet from the desk,” “The ceiling is 8 feet high,” “There are 2 chairs in the room.”)*
---
3. List 3 ways to remember the difference between qualitative and quantitative data.
> - Qualitative = Qualities (descriptions, senses, colors, smells, textures)
> - Quantitative = Quantities (numbers, measurements, counts)
> - Think: “Quantitative = Quantity” → it’s about how much or how many.
*(Bonus tip: Use the mnemonic “Qual = Quality; Quant = Quantity.”)*
---
4. How is a controlled variable different from an independent variable?
> - Independent variable: The factor that the experimenter deliberately changes or manipulates to observe its effect.
> - Controlled variable (constant): Factors that are kept the same throughout the experiment to ensure a fair test. They are not changed so they don’t affect the outcome.
>
> ➤ Example: In an experiment testing how fertilizer affects plant growth:
> - Independent variable = amount of fertilizer
> - Controlled variables = amount of water, sunlight, soil type, pot size
---
5. An independent variable is what you __________, and a dependent variable is what you __________.
> An independent variable is what you change, and a dependent variable is what you measure (or observe the effect on).
---
6. What do you need to remember about the format of a hypothesis?
> A hypothesis should be written as a clear, testable statement that predicts the relationship between the independent and dependent variables. It often follows the format:
>
> > “If [independent variable] is changed, then [dependent variable] will change because [reason].”
>
> ➤ Example: *“If plants are given more sunlight, then they will grow taller because sunlight is needed for photosynthesis.”*
> Also, it must be falsifiable — meaning it can be proven wrong through experimentation.
---
7. List the scientific questions below to identify if it’s a prediction or a hypothesis. Scientific Question: What effect does alternative homework have on students’ grades in this class?
> This is a scientific question, not yet a hypothesis or prediction.
> To turn it into a hypothesis, you would write:
> > “If students are assigned alternative homework (e.g., project-based), then their grades will improve because they are more engaged.”
> A prediction might be:
> > “Students who do alternative homework will score higher than those who do traditional homework.”
> So:
> - Scientific question → Opens inquiry
> - Hypothesis → Testable explanation with reasoning
> - Prediction → Specific expected outcome
---
> *(Note: This seems to be a typo or mislabeling. Based on context, this section is actually continuing the worksheet — likely meant to say “Read the paragraph below…” and then answer questions 8–11.)*
> Paragraph:
> *I have two potatoes that are the same size. I keep one potato baked and the same size and weight. I feed one potato two cups of milk while it’s still warm and I feed the other potato two cups of canned food. I want to see which potato grows faster. I weigh the potatoes once a week to check their weight.*
---
8. What is the independent variable in this experiment?
> The independent variable is what the experimenter changes — in this case, the type of food given to the potatoes (milk vs. canned food).
> *(Note: This experiment is flawed — potatoes don’t “grow” after being harvested, but we’re answering based on the scenario given.)*
---
9. What is the dependent variable in this experiment?
> The dependent variable is what is being measured — the weight of the potatoes over time (measured weekly).
---
10. What are the controlled variables in this experiment?
> Controlled variables (constants) are things kept the same to ensure fairness:
> - Same initial size and weight of potatoes
> - Both potatoes are baked
> - Both are fed the same volume (two cups)
> - Weight is measured at the same frequency (weekly)
> - Same environment (temperature, humidity, etc.) — assumed
---
11. Write a hypothesis for this experiment.
> > “If one potato is fed milk and the other is fed canned food, then the potato fed canned food will gain more weight because canned food contains more nutrients and calories than milk.”
> *(Note: Again, biologically incorrect — potatoes don’t absorb food like living organisms — but this is the logical hypothesis based on the setup.)*
---
12. List at least two constants related to this experiment.
> Two constants (controlled variables):
> - Both potatoes are the same size and weight initially.
> - Both are baked before feeding.
> *(You could also list: same feeding volume, same measurement schedule, same storage conditions.)*
---
## 🧪 Summary & Key Takeaways:
- Qualitative = descriptive, non-numerical.
- Quantitative = numerical, measurable.
- Independent variable = what you change.
- Dependent variable = what you measure.
- Controlled variables = what you keep constant.
- Hypothesis = testable prediction with reasoning (“If… then… because…”).
- Always control variables to isolate cause-and-effect.
---
✔ Final Tip for Students: When designing experiments, always ask yourself:
> “What am I changing?” → Independent variable
> “What am I measuring?” → Dependent variable
> “What am I keeping the same?” → Controlled variables
