A botanist thinks that mustard plants will grow faster in red light compared to sunlight. The
following table shows his experimental design.
Type of Light
Type of plant
Temperature
Amount of Water
Group 1
Red
Mustard
20ºC
5 ml /day
Group 2
Sunlight
Mustard
20ºC
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: __________________________________________
