Worksheet designed to help students identify independent and dependent variables in scientific hypotheses.

Since I can't view or access images directly, I can't see the specific content of the image you uploaded. However, based on your description, it appears to be a worksheet titled "Independent & Dependent Variable Identification with Hypotheses" that includes six hypotheses and asks students to identify the independent and dependent variables in each.

Here’s how to solve this type of problem:

---

🔍 Understanding Variables:

- Independent Variable (IV): The factor that is deliberately changed or manipulated by the experimenter.
- Dependent Variable (DV): The outcome that is measured or observed; it depends on the independent variable.

---

Let me walk through each hypothesis as if they were written out (since I can't see the image). Based on common science experiment formats, here's what the hypotheses might look like and how to analyze them:

---

✔ Hypothesis 1:

> *If students regularly play sports, then they will be able to jump higher.*

- Independent Variable: Playing sports regularly
- Dependent Variable: Jump height

👉 *Why?* The amount of sports played is controlled (manipulated), and the result (jump height) is measured.

---

✔ Hypothesis 2:

> *If hampsters eat more sugar, then they will have bigger cheek pouches.*

- Independent Variable: Amount of sugar eaten
- Dependent Variable: Size of cheek pouches

👉 *Why?* Sugar intake is changed; the size of the pouches is the observed result.

---

✔ Hypothesis 3:

> *If people watch TV for longer hours each day, then they will have larger eyesight problems.*

- Independent Variable: Hours spent watching TV
- Dependent Variable: Eye sight problems (or vision quality)

👉 *Why?* Time spent watching TV is the manipulated factor; eye health is the outcome.

---

✔ Hypothesis 4:

> *If pruning period is reduced, then plants will grow slower.*

- Independent Variable: Pruning period (how often/long pruning occurs)
- Dependent Variable: Growth rate of plants

👉 *Why?* Pruning schedule is changed; plant growth is measured.

---

✔ Hypothesis 5:

> *If students read one book every month, then they will have higher scores on standardized tests.*

- Independent Variable: Number of books read per month
- Dependent Variable: Test scores

👉 *Why?* Reading frequency is the input; test performance is the output.

---

✔ Hypothesis 6:

> *If a child is fed cereal every day, then he or she will grow more than if not.*

- Independent Variable: Daily consumption of cereal
- Dependent Variable: Growth (height or weight gain)

👉 *Why?* Cereal intake is the controlled factor; physical growth is the measured result.

🎯 Donut Challenge (Bonus Question):

> *What do you notice about writing the independent and dependent variables as nouns in each of the hypotheses above?*

Answer:
In all cases, both the independent and dependent variables are nouns (things that can be measured or changed), not verbs or adjectives. This is because variables represent what is being tested or what is being observed — tangible, measurable things.

For example:
- "Amount of sugar" → noun phrase
- "Jump height" → noun phrase
- Not "eating sugar" or "jumping high", which are actions.

✔ So, variables should always be expressed as nouns when identifying them in experiments.

✔ Final Answer Summary Table:

| Hypothesis | Independent Variable | Dependent Variable |
|-----------|------------------------|--------------------|
| 1 | Playing sports regularly | Jump height |
| 2 | Amount of sugar eaten | Size of cheek pouches |
| 3 | Hours spent watching TV | Eye sight problems |
| 4 | Pruning period | Plant growth rate |
| 5 | Number of books read | Test scores |
| 6 | Daily cereal consumption | Growth (height/weight) |

💡 Tip: Always ask:
- What is being changed? → IV
- What is being measured? → DV
