They need photosynthesis to live and grow. They require water, co2, and enegy |
Research Question |
How does the different type of water "tap, rain/melted snow, creek water, and bottled water" effect the rate of germination. |
Predictions |
If we change the water we use to water plants "tap, rain/melted snow, creek, and bottled water" then the pea seed will grow the most in rain/melted snow, next will be creek, next will be bottled, and lastly will be tap. |
Experimental Design |
Step 1: Collect all materials
Step 2: Place a paper towel in each of the 4 petri dishes
Step 3: Place 3 pea seeds in each of the 4 petri dishes
step 4: measure ph level of each water
Step 5: Add 5mL of each type of water- Tap, Bottled, Melted Snow/Rain, Creek- to each correspondingly labeled petri dish.
Step 6: Leave seeds at school overnight
Step 7: Observe and record data. Also measure the length of the root/sprout
Step 8: Repeat steps 5-7 each day for six days |
Conclusion |
Claim: If you water a Pea seed for 5 days with tap, rain/melted snow, creek, and bottled water then the seed watered by the bottled water will grow the most, and tap seed grew the worst.
Evidence: My evidence supports my claim because bottled water had an average root length of 4.4 cm, tap had only an average of 1.5 cm, and rain/snow, had a normal average of 4.14 cm, while creek had also a normal average of 4 cm. By the 5th day.
Reasoning: This happens because Bottled water Has vitamins and minerals in it like,like iron and zinc, that helped the seed grow and germinate. Tap did the worst because it is very unnatural, has different chemicals in it like fluorine, and even has metals in it like aluminum, copper, and lead which is poisonous. Rain and creek water we expected to do alright because that is what plants out in the wild usually use to germinate and perform photosynthesis. We did not expect for bottled to do the best, but we did think tap would not do to hot. This was a fair test because we used the same amount of water on the same days for the same amount of time with the same seeds in the same environment. |
