Question

for each experiment, write down the independent variable (iv), dependent variable (dv), and what controls should be used.

1. katiana wanted to figure out what type of liquid worked best for growing beans. she watered one with coca - cola, one with lemonade, and one with just water. after one week, she measured how high they had grown.

independent variable (iv):
dependent variable (dv):
control:

Explanation:

The independent variable is what is changed in an experiment. Here, the type of liquid is being changed. The dependent variable is what is measured as a result of the change in the independent variable, which is the height of the beans. Controls are factors kept the same to ensure a fair test. In this case, factors like the type of bean, amount of sunlight, temperature, and pot size should be the same.

Answer:

Independent Variable (IV): Type of liquid (coca - cola, lemonade, water)
Dependent Variable (DV): Height of the beans
Control: Type of bean, amount of sunlight, temperature, pot size
