Experiment 1
Auxins: How do auxins affect plant growth?

Purpose/Hypothesis

In this experiment, you will try to produce new plants from stem and leaf cuttings. You will treat half of the cuttings with the plant hormone auxin, while the other half will not be treated. The difference between the two groups of cuttings in root, leaf, and stem growth will tell you whether auxin makes any difference. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of plant propagation. This educated guess, or prediction, is your hypothesisAn idea in the form of a statement that can be tested by observation and/or experiment.. A hypothesis should explain these things:

• the topic of the experiment
• the variable you will change
• the variable you will measure
