Scientific Evidence: Reliable or Not? – Grade Nine
This lesson engages students in recognizing some of the concepts of scientific evidence (e.g., reliability and validity). Students will be given the opportunity to read an article and determine if it provides reliable scientific evidence. Students will be given the opportunity to apply concepts of scientific evidence to exemplar student lab reports and to demonstrate whether data generated by their scientific inquiries are, or are not, reliable and valid (e.g., make multiple measurements, select appropriate instruments, use instruments correctly, compare data, treat data respectfully, control variables, measure the right variable). The lesson also provides an opportunity for students to research and report on information regarding other concepts of scientific evidence (e.g., ethical processes, critical scientific peer review) that help scientists ensure that scientific processes construct effective and dependable knowledge about the physical universe.
