1. karen 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.
a. independent variable (iv):
b. dependent variable (dv):
c. constants:
d. experimental group:
e. control group:

IV: liquids

DV: beans

Constants: none (?)

Experimental Group: coca-cola and lemonade watered beans

Control Group: beans with water

Explanation:

i'm almost certain there are no constants in the scenario

The various variables and their examples  are :

a) Independent variable : Liquids

b) Dependent Variable : Beans growth

c) Constant : Beans

d) Experimental Group : Beans watered with Coca-Cola and lemonade

e) Control Group : Beans watered with water

An independent variable in an experiment is the variable that has a direct effect on the dependent variables in an experiment, and in this experiment the type of liquid has a direct effect on the dependent variable ( Beans growth ).

The dependent variable in this experiment it is the beans growth because is dependent on the type of liquid used

The amount of beans used in the experiment is constant in this experiment

The control group in an experiment is the group not subjected tot the experimental process but serves as a measuring/reference group in the experiment. ( i.e. beans watered with clean water )

Experimental group : The experimental group is the group exposed to the independent variable ( beans watered with Coca-Cola and Lemonade )

Hence the various variables associated with the experiment are as listed above.
