Date _______ Mid-Term Review Name _______________Chapter 1 – Intro to Biology
A botanist thinks that mustard plants will grow faster in red light compared to sunlight. The following table shows his experimental design.
Group 1 Group 2Type of Light Red SunlightType of plant Mustard MustardTemperature 20ºC 20ºCAmount of Water 5 ml /day 5 ml/day
The botanist measures the height of each plant daily and uses this information to calculate a growth rate after a two-week period. He concludes that his hypothesis is incorrect because the plant in sunlight showed a faster growth rate than the plant in red light. Identify each of the following:
1. Independent variable: __________________________________________2. Dependent variable: ___________________________________________3. Experimental group: ___________________________________________4. Control group: ______________________________________________5. Why is a control necessary for a good experiment? ___________________________
