Generating Experimental IdeasThe Four Question Strategy
Cothron, Giese, & Rezba. Students and Research. Kendall/Hunt 1989
1. What materials are readily available for conducting experiments on (plants)?Soils, Water, Radish Plants & Seeds, Light, Carbon Dioxide, Containers, …
2. How do (plants) act?Plants grow.
The Four Question Strategy3. How can you change the set of (plant) materials
to affect the action?Earth —type
—compaction
Air —composition
—temperature
4. How can you measure or describe the response of (plants) to the change?
Measure the height, Number that germinate, Count the number of leaves, Health of plant
Water —method of application—amount—acidity
Fire —amount of light—intensity of light
5. How does your experiment model the environment?
