Experimental DesignOUT OF THE 100 BEAN SEEDSI PLANTED IN MY GARDEN, ONLY 35 GERMINATED INTOHEALTHY PLANTS? HOW CAN I INCREASE THE PERCENT OFBEAN SEEDS THAT GERMINATE?

Seed Germination

Variables in Seed Germination

Temperature of Soil

Amount of Light Amount of Water

Percent of seeds that germinate

Amount of Time

Type of Seed

THE HYPOTHESIS

• CHANGE ONLY ONE INDEPENDENT VARIABLE,

• WHICH SHALL IT BE? oC, H2O, Light, Time

IF ___(independent variable)_____ IS __(describe change)___

IF THE IS INCREASED

THEN __(dependent variable)___ will __(describe change)__

THEN THE WILL INCREASE

THE EXPERIMENT

Levels of the IV (Drops per hour)

Number of Trials

IV: Amount of Water

DV: Percent of Seed Germination

Constants:1. 2.

3. 4.
