Answer 1

The independent variable in this experiment is the type of liquid used to clean the shower. The dependent variable is the appearance of the green slime on the shower. Neither lemonade juice nor water had any effect on the appearance of the green slime on the shower.

Step-by-step explanation:

The independent variable in this experiment is the type of liquid used to clean the shower (lemonade juice or water). The dependent variable is the appearance of the green slime on the shower. The control in this experiment would be a section of the shower that is not sprayed with either lemonade juice or water. The conclusion would be that neither lemonade juice nor water had any effect on the appearance of the green slime on the shower.

Answer 2

The correct answer is :

Independent Variable: side of the shower with lemon juice

Dependent Variable: cleanliness of shower

Control: spray of water

Conclusion: lemonade juice have no effect on slime

Step-by-step explanation:

Independent variable in any experiment is the variable that is changed or manipulated as here side of the shower that is sprayed with lemonade juice is manipulated to see if there is any effect on the cleanliness of shower.

Dependent variable is the variable that is observed or measured to check if manipulated variable or independent variable have any effect on it, like the cleanliness is measured to check if lemonade juice clean the slime of the side or not.

The control is something that remains the same to check the condition or effect that is not changed or can be compared to it. Water spray is control in this case.

The conclusion of this experiment is that there is no effect of lemonade juice on the cleanliness of slime present in the shower
