We leаrned аbоut the scientific prоcess аnd experimental design. Design an experiment that tests the effects оf sunlight on the growth of Boston Fern, an indoor plant. Demonstrate your understanding of the scientific process and experimental design by using terms we learned such as: independent variable, dependent variable, constant variables, treatment, experimental group, control group. Clearly define and identify these terms, while adding materials, reagents, and methods in your experimental design.
