A new school is being built in a field of wildflowers. A class wanted to develop a research project to predict the effects of the new school on wildflower species. When would be the best time for the class to conduct the study?
The best time would be as soon as the school is built. When it is finished, they should begin and then measure how it has changed over a chosen time span.
The best time for the class to do the study would be right after the school is built, giving some data on how the school effected the flowers so far. This would help in predicting the future effect on the flower species.
