re-writing the method.

AIM: To determine weather water temperature affects plant growth .

HYPOTHESIS: When water is too hot or too cold, the growth rate will decrease.

EQUIPMENT:
- 16 violas (flowers)
- fertilised soil
- 4 rectangle pots
- thermometre
- tap water
- ice cubes
- 20mL measuring cup.
- sink hole blocker.

METHOD:
Steps taken:

1. 6 holes were poked through the 4 pots to allow excessive water to escape the pot.

2. 4 pots were filled up with fertilised soil.

3. 16 violas were planted in the pots - 4 in each pot.

4. Pots were placed in an atmosphere with a temperature or 20 degrees Celsius.

5. First pot was named number 45; second pot was named number 35; third pot was named number 25 and the fourth pot was named number 15.

5. Using the thermometre to measure the temperature, tap water of 45 degrees celsius was obtained.

6. 20mL of 45 degrees celsius tap water was taken using the 20mL measuring cup, and one plant in pot number 45 was watered.

7. Step 6 was repeated with all four of the plants in pot number 45.

8. Using the thermometre to measure the temperature, tap water of 35 degrees celsius was obtained.

9. 20mL of 35 degrees celsius tap water was taken using the 20mL measuring cup, and one plant in pot number 35 was watered.

10. Step 9 was repeated with all four of the plants in pot number 35.

11. Using the thermometre to measure the temperature, tap water of 25 degrees celsius was obtained.

12. 20mL of 25 degrees celsius tap water was taken using the 20mL measuring cup, and one plant in pot number 25 was watered.

13. Step 12 was repeated with all four plants in pot number 25.

14. USing the thermometre to measure the temperature, tape water of 15 degrees celsius was obtained (N.B. since the tap water used had a minimum temperature of 17 degrees celsius, ice cubes were used to lower the temperature in order to obtain water of 15 degrees)

13. 20mL of 15 degrees water temperature was taken using the 20mL measuring cup, and one plaint in pot number 15 was watered.

14. Step number 13 was repeated with four plants in pot number 15.

15. Steps 5-14 were repeated everyday for one week.

16. Plants were observed and results were recorded.
