2. what effect does studying with music have on student test scores? hypothesis: independent variable: dependent variable: 3. what effect does food color have on the amount of food fish eat? hypothesis: independent variable: dependent variable: 4. what effect does light have on plant growth? hypothesis: independent variable: dependent variable:
Answer
Explanation:
Step1: Define hypothesis for studying with music
A possible hypothesis could be "Studying with music will either increase or decrease student test - scores compared to studying without music".
Step2: Identify independent variable for studying with music
The independent variable is whether or not music is present during studying.
Step3: Identify dependent variable for studying with music
The dependent variable is the student test - scores.
Step4: Define hypothesis for food color and fish food intake
A possible hypothesis could be "The color of the food will affect the amount of food fish eat, with brighter colors leading to more or less consumption".
Step5: Identify independent variable for food color and fish food intake
The independent variable is the color of the food.
Step6: Identify dependent variable for food color and fish food intake
The dependent variable is the amount of food the fish eat.
Step7: Define hypothesis for light and plant growth
A possible hypothesis could be "Increasing or decreasing light availability will affect plant growth positively or negatively".
Step8: Identify independent variable for light and plant growth
The independent variable is the amount or intensity of light.
Step9: Identify dependent variable for light and plant growth
The dependent variable is the plant growth (which could be measured by height, number of leaves etc.).
Answer:
- Hypothesis: Studying with music will either increase or decrease student test - scores compared to studying without music. Independent variable: Whether or not music is present during studying. Dependent variable: Student test - scores.
- Hypothesis: The color of the food will affect the amount of food fish eat, with brighter colors leading to more or less consumption. Independent variable: The color of the food. Dependent variable: The amount of food the fish eat.
- Hypothesis: Increasing or decreasing light availability will affect plant growth positively or negatively. Independent variable: The amount or intensity of light. Dependent variable: Plant growth.
