- Explore the concept of scientific inquiry.
- Practice formulating hypotheses and designing an experiment.
- Understand how data are collected and analyzed in an experiment.
- Critique a scientific investigation to determine if the right conclusions are based on results of real data.
- Gain an appreciation of science in action and how many questions arise from an experiment.
Context for Use
- Go to the website entitled "Which Pest Control is Best for Basil?" The MERLOT description and link can be found at http://www.merlot.org/merlot/viewMaterial.htm?id=232278 and the direct link can be found at http://www.mhhe.com/biosci/genbio/tlw3/virtual_labs/lab17/home.html
- Follow the steps as outlined at the website including: 1) Explore the issue being investigated, 2) Read the original paper, 3) Gain an overview of the experiment, and 4) Run a virtual experiment exploring the original paper.
- In "Explore the issue being investigated," discuss the treatments being investigated and hypothesize how different pest methods may be more or less effective in deterring herbivory. Introduce the concept of a control and how the "null" and "alternate" hypotheses may be written.
- After reading the paper, discuss which sentences in the introduction include experiments that can be tested by the null and alternate hypothesis. For instance, discuss how the sentence, "...determining the influence of harvest date and pest control treatment on yield and metabolism..." can be worded to include null and alternate hypotheses.
- Proceed briefly to the "Meet the investigator" section to learn about science in action and what types of questions lead scientists to research projects.
- Learn about how data are collected and interpreted in the section entitled, "Gain an overview of the experiment."
- Run the virtual experiment and discuss the results. Determine whether or not the experiment was properly conducted, appropriately interpreted, and what types of experiments might be planned for the future.
- Discuss whether or not good research raises more questions than those answered by specific experiments and if so, how this contributes towards scientific knowledge.
