Think about the various factor shown in the experiment in the video for each factor, determine whether the factor was independent variable, changed on purpose, the dependent variable might have changed as the result of experiment, or a controlled factor, kept the same on purpose
1. Type of Music Played:
- Independent variable: Changed on purpose as different types of music were played to see how it affected the plants.
- Dependent variable: Might have changed as a result of the experiment, as the different types of music could have influenced the growth of the plants.
- Controlled factor: Kept the same on purpose for all plants except for the type of music playing.
2. Watering Schedule:
- Independent variable: Changed on purpose as the watering schedule was varied between the plants.
- Dependent variable: Might have changed as a result of the experiment, as the frequency of watering could have affected the growth of the plants.
- Controlled factor: Kept the same on purpose for all other conditions except for the watering schedule.
3. Amount of Light:
- Independent variable: Changed on purpose as the amount of light was varied for different plants.
- Dependent variable: Might have changed as a result of the experiment, as light exposure can affect plant growth.
- Controlled factor: Kept the same on purpose for all other conditions except for the amount of light.
4. Type of Plant:
- Independent variable: Not explicitly mentioned in the video, but it can be assumed that different types of plants were used in the experiment.
- Dependent variable: Might have changed as a result of the experiment, as different types of plants may respond differently to the other factors.
- Controlled factor: Not explicitly addressed in the video, but it can be assumed that all other conditions were kept the same for the different types of plants to isolate the effects of the other factors.
