WebUsing Google forms, students answer questions about experimental background, procedure and lab safety that correlate with published BASIL experiments. Using a mix of multiple choice, free response, and video/ image-based questions, students engage with the material at a deeper level despite not being physically present in the lab. You should begin with a specific research question. We will work with two research question examples, one from health sciences and one from ecology: To translate your research question into an experimental hypothesis, you need to define the main variables and make predictions about how they are related.
