1Question

What is one reason a robot might be used to study plants in a greenhouse?

2Question

Name one plant part that a robot could measure when monitoring plant growth.

3Question

What sensor could a robot use to check how much light a plant is receiving?

4Question

Why is watering plants automatically with a robot useful in a classroom or greenhouse?

5Question

If a robot is programmed to water a plant every 2 days, how many times will it water the plant in 10 days?

6Question

What is one difference between a plant’s needs and a robot’s needs?

7Question

A soil moisture sensor reads 20% in one pot and 65% in another. Which plant likely needs water more urgently?

8Question

What does a robot’s program do when it controls a plant-care system?

9Question

Why might a robot use a temperature sensor near plants?

10Question

A robot records plant height as 8 cm on Monday and 11 cm on Friday. How much did the plant grow?

11Question

What is one advantage of using a robot to collect plant data instead of a person?

12Question

A robot checks three plants. Their heights are 10 cm, 12 cm, and 15 cm. What is the tallest plant height?

13Question

What plant response might a robot observe if a plant is receiving too little light?

14Question

A robot gives 50 mL of water to each of 4 plants. How much water does it give in all?

15Question

Why should a robot’s watering system be tested before use on real plants?

16Question

If a robot collects plant data every day for 2 weeks, how many days of data will it collect?

17Question

Describe one way a robot could help with pollination in agriculture or a science project.

18Question

A robot measures the following leaf lengths: 4 cm, 5 cm, 6 cm, and 5 cm. What is the average leaf length?

19Question

What is one reason plants in a greenhouse may need a robot-controlled system instead of manual care only?

20Question

A plant needs water when the soil moisture is below 30%. The sensor reads 28%. Should the robot water the plant? Explain briefly.

21Question

How could a robot use both a light sensor and a moisture sensor to help a plant grow better?

22Question

A robot is programmed to water plants only if the soil moisture is below 25% and the temperature is above 20°C. The moisture is 22% and the temperature is 19°C. Should the robot water the plant?

23Question

What is one possible problem if a robot waters a plant too often?

24Question

A robot monitors 6 pots. It finds that 2 pots need water, 3 pots need more light, and 1 pot is healthy. What fraction of the pots need water?

25Question

Design a simple robot system for plant care. Name two sensors it should use and explain what each sensor helps the robot do.

Answer Key

#	Answer
1	A robot can collect data consistently and help study many plants without getting tired.
2	A robot could measure stem height, leaf size, or leaf count.
3	A light sensor.
4	It helps plants get the right amount of water on a regular schedule.
5	5 times.
6	Plants need water, light, and nutrients to grow, while robots need power and programming to operate.
7	The plant in the pot with 20% moisture likely needs water more urgently.
8	It tells the robot what actions to take and when to take them.
9	To make sure the plants stay in a safe temperature range for growth.
10	3 cm.
11	A robot can collect data the same way each time and reduce human error.
12	15 cm.
13	The plant may grow toward the light or become weak and slow-growing.
14	200 mL.
15	So it can be checked for mistakes and avoid overwatering or underwatering.
16	14 days.
17	A robot could move pollen from one flower to another to help plants reproduce.
18	5 cm.
19	A robot-controlled system can keep conditions more consistent and save time.
20	Yes, because 28% is below 30%.
21	It can check light and water levels and adjust care to match the plant’s needs.
22	No, because the temperature condition is not met.
23	The roots may get too wet, which can harm the plant.
24	2/6, which simplifies to 1/3.
25	Example answer: Use a soil moisture sensor to decide when to water and a light sensor to check if the plant gets enough light.
