Control Groups: Groups that serve as a standard for comparison in experimental studies. They are similar in relevant characteristics to the experimental group but do not receive the experimental intervention.
The scientific method is a detailed, empirical, problem-solving process leveraged by biologists and scientists of other disciplines. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions. Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these experiments, the original explanation may need to be refined, and new hypotheses and questions can be generated. Importantly, this illustrates that the scientific method is not a stepwise recipe. Instead, it is a continuous refinement and testing of ideas based on new observations, which is the crux of scientific inquiry. Science is mutable and continuously changes as we learn more about the world around us. For this reason, scientists avoid claiming to ‘prove’ a specific idea. Instead, they gather evidence that either supports or refutes a given hypothesis. A hypothesis is preceded by an initial observation, during which information is gathered by the senses (e.g., vision, hearing) or using scientific tools and instruments. This observation leads to a question that prompts the formation of an initial hypothesis, a (tes…
Exponential Population Growth Model
NOTE: In these experiments you will use computer software to simulate different types of growth models. HYPOTHESES: The experimental hypothesis might be that if we increase either R, the reproductive rate or the initial population size, NT, that this will increase the population size after 10 generations in an…
