It looks like you've uploaded an image of a worksheet titled
"Let's Learn What We Know!" which is designed to assess students' understanding of the
scientific method and related concepts. The worksheet includes several questions and diagrams, but since I can't view images directly, I'll guide you on how to solve it based on typical content for such worksheets.
Here’s a breakdown of what the worksheet likely contains and how to answer each section:
---
Section 1: Complete the Sentences with the Correct Vocabulary
This section probably asks you to fill in blanks using scientific method terms like:
- Hypothesis
- Experiment
- Observation
- Conclusion
- Variable
- Control group
- Independent variable
- Dependent variable
Example Question:
*"A ________ is a possible explanation for an observation."*
✔ Answer: *Hypothesis*
> 🔍 Tip: Review the steps of the scientific method:
> 1. Ask a question
> 2. Do background research
> 3. Construct a hypothesis
> 4. Test with an experiment
> 5. Analyze data
> 6. Draw a conclusion
> 7. Communicate results
---
Section 2: Match the Terms with Their Definitions
You might be asked to match words like:
-
Control group → Group that does not receive the experimental treatment
-
Independent variable → The factor changed by the experimenter
-
Dependent variable → The outcome measured
-
Constant → Factors kept the same throughout the experiment
Example:
Match "the thing being tested" →
✔ Independent variable

Section 3: Look at the Pictures and Answer the Following Questions
There are usually two or three small diagrams showing experiments (e.g., plants under different conditions, a test with liquids, etc.).
####
Example Scenario:
Two plants — one in sunlight, one in darkness.
Questions:
1.
What is the problem?
➤ *"How does light affect plant growth?"*
2.
What is the hypothesis?
➤ *"Plants grow better in sunlight than in darkness."*
3.
What is the independent variable?
➤ *"Amount of light"*
4.
What is the dependent variable?
➤ *"Plant growth (height)"*
5.
What are the constants?
➤ *"Same type of plant, same soil, same water amount, same pot size"*
6.
Which is the control group?
➤ *"The plant in darkness (or the one with normal conditions, depending on setup)"*
7.
What is the conclusion?
➤ *"Plants need light to grow properly."*

Common Diagrams You Might See:
- A scientist measuring something (observation)
- Two beakers with different liquids (experiment)
- A chart with data (analysis)

✔ How to Solve It Step-by-Step:
1.
Read each question carefully.
2.
Identify key terms (hypothesis, variable, control, etc.)
3.
Use context clues from the pictures.
4.
Apply the scientific method logic:
- What was changed?
- What was measured?
- What stayed the same?
