-Work Division
Everyone will plant the green bean and make a deep investigation about a 10 days experiment.
-Jasper have divide us in to different jobs and give us the method to achieve our aims and goals

TimeLine
28/11 10days observation-> 10/12 Collect data-> 11/12 Doing report-> 13/12 Deadline

1. Objective
We will strive to discover the difference of the plant which is using different type water to plant.
Besides, we will also discover the reason why the difference will change the growth rate

2. Hypothesis
Using tap water to plant will have faster growth rate instead of salt water
3. Materials
1 cup, 3 green beans, 30g of cottons

4. Table of variables
Control
variables
Dependent variables
Independent
variables
Amount and kind of cottons
Growth rates of each plants
Type of water
Amount of water
Height of each plant

Amount and kind of beans

Same size of cup

Same environment

5. Experiment procedures
-SETUP
1. Put 20g of cotton to the bottom of the two cups
2. Put two beans at the top of the cottons in both cups
3. Sprinkle them with salt water in the first cup, and sprinkle the others one with tap water
-MEASURE
Our measuring Units is the height which is centimeter
We will use the ruler to measure the growth

-TIMES
We will grow the beans for 10 days and we will observe them by taking photo and we finally got 5 days data for both plants

6. Result
What I observe-
1. I can observe that those green bean which is sprinkle by tap water will be looking greener and they grow faster and stronger, their leaves is sharp.
2. I can observe that the green beans which is sprinkle by salt water couldn’t grow or even have their skin off and grow high
