Table 1.
Sample hypotheses, experiments, and predictions for plasticine model caterpillar experiments.
HypothesisPredictionExperiment
Caterpillar color affects predation. Camouflaged caterpillars will suffer higher predation than aposematically colored caterpillars. Set out green and red caterpillars. 
Plant type affects predation. Caterpillars on shrubs will have higher predation than caterpillars on trees. Place caterpillars on trees and shrubs. 
Predation differs between habitats. Caterpillars in an open area will have higher predation than those placed in the forest. Deploy some caterpillars in a forested area and others in an open area. 
Predation is different for caterpillars placed at different heights. Caterpillars located 0.5 m above ground will experience greater predation than caterpillars located 1 m above ground. Place caterpillars 0.5 m and 1 m above ground.
