Plant growth line graph worksheet for students to plot data and answer questions.

Let’s go step by step using the data from the table:

Table Data:
- Week 1 → Height = 2 cm
- Week 2 → Height = 5 cm
- Week 3 → Height = 8 cm
- Week 4 → Height = 11 cm
- Week 5 → Height = 14 cm

---

Question 1: How tall was the plant in week 2?
Look at the table — Week 2 height is 5 cm.

✔ Answer: 5 cm

---

Question 2: How much had the plant grown from week 1 to week 2?
Week 1: 2 cm
Week 2: 5 cm
Growth = 5 - 2 = 3 cm

✔ Answer: 3 cm

---

Question 3: How much had the plant grown from week 2 to week 4?
Week 2: 5 cm
Week 4: 11 cm
Growth = 11 - 5 = 6 cm

✔ Answer: 6 cm

---

Question 4: How much had the plant grown from week 1 to week 5?
Week 1: 2 cm
Week 5: 14 cm
Growth = 14 - 2 = 12 cm

✔ Answer: 12 cm

Question 5: On week 6, do you think the plant would be around 21 cm or 17 cm?

Let’s look at the pattern of growth each week:

- Week 1 to 2: +3 cm (2 → 5)
- Week 2 to 3: +3 cm (5 → 8)
- Week 3 to 4: +3 cm (8 → 11)
- Week 4 to 5: +3 cm (11 → 14)

The plant grows 3 cm every week.

So, if this pattern continues:

→ Week 6 = Week 5 + 3 cm = 14 + 3 = 17 cm

21 cm would mean it grew 7 cm in one week — that breaks the pattern.

✔ So, the best guess is 17 cm

Final Answer:
1. 5 cm
2. 3 cm
3. 6 cm
4. 12 cm
5. 17 cm
