Ashley hypothesizes that adding coffee grounds to the soil will help the plants grow faster. She designs a controlled experiment to determine if this hypothesis is supported.She grows one group of soybean seedlings under normal conditions. She mixes three tablespoons of coffee grounds into the soil of the second group and grows the seedlings under the same light, temperature, and watering regimen. After three weeks, she measures the height of the seedlings and compares the two groups.Identify the parts of the experiment. Place only one term in each category. You will not place all the terms.

The purpose of this study is to determine theexperimental group,thecontrol group,thedependent variable,and theindependent variable.Designing and carryingout anexperimentis the best approach to prove whether ahypothesisistrue or incorrect.To ensure that anexperimentexamines exactly what thehypothesis claims, scientistsmust be cautious in how they construct it.To ensure that only one factor is being altered in an experiment, the independent variables are therefore divided into two groups.The control groupThe experimental groupThecontrol groupdoes not experience any changing variable.The experimental groupreceives all of the experiment's circumstances, changes as well as the one variable that the experiment is testing.In Ashley's experiment:The experimental group:Seedlings grown with coffee grounds.The control group:Seedlings grown without coffee grounds.The dependent variable:Seedling heightThe independent variable:SoilTherefore, we can conclude that we understand theconcept of the experimentcarried out by Ashley.Learn more about thehypothesishere:brainly.com/question/23056080?referrer=searchResults...
