Question

Please read the two scnarious and answer the questions:

Scenario #1
Ten pea plant seeds were planted in each of 5 pots that contained 500g of “Peat’s Potting Soil.” The pots were given the following amounts of distilled water each day: Pot 1, 50ml; Pot 2, 100ml; Pot 3, 150ml; Pot 4, 200ml; Pot 5, 250ml. According to the pea seed package, the recommended of water for the pea plants was 150ml of water daily. After 40 days, the height of each plant was measured in centimeters.

Scenario #2
Sandy wanted to find out if the color of food would affect whether or not kindergarten children would select it for lunch. She put food coloring into 4 identical bowls of mashed potatoes. The colors were red, green, yellow, blue. One bowl of mashed potatoes was left as the regular white color. Each child was given the choice to choose the bowl of mashed potatoes of the color of their choice. Each day she recorded the choice of 100 different students. She did this for five days.

Repeat or scenario 2

Answer 1

Scenario 1

• Title: ​Effect of water content on the growth of potted pea plant.
• Hypothesis: Provided with same soil condition, Water content play important role in determining the physical growth of plant. Abundance of water (that is, amount above the critical daily requirement) as well as scarcity of water (that is, amount below the critical daily requirement) affects the growth of water in different ways.
• Independent Variable: It is the condition that we are changing in the experimental scenario. Here, it is the Amount of water supply to the potted plant.
• Description of Groups

Pot	No. of seeds	Amount of water (ml)	Height of plant (cm),after 40 days.
1.	10	50	-
2.	10	100	-
3.	10	150	-
4.	10	200	-
5.	10	250	-

• Repeated no. of trials: 10 for each sets of experiment.
• Dependent Variable: It is the condition that we are going to observe in different conditions of independent variable. Here it is the Height of potted pea plant.
• Control: The pot with water quantity 150ml will be taken as control.
• Constants: These are the conditions which are kept similar for every set of experiments. In this scenario, these may be taken as constant:

1. Amount of light exposure 2. Temperature 3. Volume of pot 4. Variety of seed.

Scenario 2

• Title: Effect of colour on food preferences by children.
• Hypothesis: Children prefer coloured dishes for their lunch. Different colours imposes different sorts of attraction and platability for children.
• Independent variable: Various colours put in bowls of mashed potato.
• Description of groups:

Bowl	Colour	No. of students preferred for Days 1 2 3 4 5
1.	regular white
2.	Red
3.	Green
4.	Yellow
5.	Blue

• Repeated no. of trials: 500 times.
• Dependent Variable: selection of bowls by children.
• Control: Bowl with mashed potato of regular white colour.
• Constants:

1. Age of children. 2. Time of previous feeding 3. Type of food previously taken 4. Type of dish in each bowl.
