Ответ:

Sure, I'd be happy to help you identify the independent and dependent variables in each scenario:

1. Independent variable: Amount of time playing video games

Dependent variable: Student's reaction time

2. Independent variable: Amount of light the plant gets

Dependent variable: Height of the plant

3. Independent variable: Amount of vegetables eaten

Dependent variable: Performance in sports

4. Independent variable: Grade of middle school students (6th, 7th, or 8th grade)

Dependent variable: Jump height of the students

If you have any more questions or need further assistance, feel free to ask!

Answer 2

Certainly, I can help you identify the independent and dependent variables in each of the scenarios you provided:

1. Ms. Holstein wanted to see if the amount of time playing video games affects a student's reaction time. a. Independent variable: The amount of time playing video games. b. Dependent variable: The student's reaction time.

2. Nick wanted to see how much light a plant gets helps it to grow taller. a. Independent variable: The amount of light the plant receives. b. Dependent variable: The height of the plant.

3. Bre wants to know if eating more vegetables makes you better at sports. a. Independent variable: The amount of vegetables eaten (diet). b. Dependent variable: Performance in sports (skill, ability).

4. Von wondered which grade of middle school students (6th, 7th, or 8th grade) could jump the highest. a. Independent variable: The grade of middle school students (6th, 7th, or 8th grade). b. Dependent variable: The height of their jump.

In each scenario, the independent variable is what is being manipulated or tested, while the dependent variable is what is being measured or observed as a result of changes in the independent variable.
