Exploring Scientific Method Scenarios

The video tutorial explores three scientific method scenarios. The first scenario tests a sports drink's effectiveness compared to water in hydrating runners. The second scenario examines whether increased protein intake aids problem-solving abilities. The third scenario investigates if classical music exposure enhances plant growth. Each scenario involves identifying control and experimental groups, independent and dependent variables, and analyzing the results.

What is the normal condition in the first scenario involving runners?

• Running without hydration

• Hydrating with water

• Hydrating with sports drink

• Running less than 20 miles

In the first scenario, what is being manipulated?

• The weather conditions

• The distance run

• The type of hydration

• The number of runners

What is the independent variable in the first scenario?

• The number of miles run

• The type of beverage consumed

• The number of volunteers

• The time taken to complete the run

What data is being collected in the first scenario?

• The number of runners

• The type of beverage

• The time taken to complete the runs

• The weather conditions

In the second scenario, what is the control group?

• People fed only protein

• People fed traditional meals

• People fed double protein meals

• People not fed at all

What is the experimental group in the second scenario?

• People fed traditional meals

• People fed only protein

• People fed double protein meals

• People not fed at all

What is the independent variable in the second scenario?

• The type of meals provided

• The number of people

• The duration of the experiment

• The type of puzzles

What is being measured in the second scenario?

• The ability to solve puzzles

• The number of meals

• The number of people

• The amount of protein

In the third scenario, what is the control group?

• Plants exposed to jazz music

• Plants not exposed to music

• Plants exposed to classical music

• Plants exposed to rock music

What is the dependent variable in the third scenario?

• The amount of sunlight

• The temperature

• The type of music

• The amount of growth
