Answer:
independent variable: Temperature
dependent variable: Plant growth
experimental control/constants: Same type of beans
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response. According to this question, the experimenter changes the TEMPERATURE to determine the beans' growth. Hence, TEMPERATURE is the Independent variable.
The dependent variable is the variable that the experiment measures in an experiment. In this case, the measured variable, which is the PLANT GROWTH is the dependent variable.
Experimental control or constants or controlled variable is the variable that is kept unchanged by the experimenter throughout the experiment. In this case, the experimenter will use the SAME BEANS for all groups of the experiment. Therefore, the BEANS is the constant.
