Acclimation: the process of an organism adjusting to change in its environment, allowing it to survive changes in temperature, water and food availability, etc. This adjustment occurs within the span of days to weeks (within the organism’s lifetime). Adaptation: the evolutionary process whereby a population becomes better suited to its habitat. This takes place over many generations. Designing an Experiment: A: Puzzling Observation- There are two different washes of brittlebushes found at South Mountain Park. B: Causal Question- Why are there two different washes of brittlebushes found at South Mountain Park? (two feet tall with large leaves and one foot tall with small leaves) C: Hypotheses- The brittlebushes are different because they have each adapted. OR The brittlebushes are different because they have acclimated. D: Experiment- Uproot 3 of each plant and place them in the opposite area (place three large-leaf plants where the small-leaf ones are growing, etc) and test to see if, over the series of two months, the leaf size or the height of the plant is altered. Measure for both areas, recording the height and average leaf size (found by the
