Scientific methodology is a cornerstone of modern science. This video introduces scientific methodology by describing its development and purpose. Then, using the basic question “Do plants need light to grow?”, the viewer is given a detailed illustration of how scientific methodology is applied. This includes identifying the problem or question, gathering relevant data, formulating a hypothesis, testing the hypothesis through observation and experimentation, and acceptance, modification or rejection of the hypothesis. The concepts of theory and scientific law are also addressed.
This video is a useful tool for introducing young students to the concept of scientific method, or for refreshing the knowledge of students looking to understand more.
