The Life and Death of Spontaneous Generation is a 20 page PowerPoint with embedded teacher notes that begins with Aristotle and concludes with Pasteur.
This section is designed to strengthen several standards within Scientific Method and Inquiry. As it leads students through the advancement of technology, specifically the microscope, it debunks the Theory of Spontaneous Generation by including the scientists and their methods that disproved a theory in existence for over 2,000 years. Four other key scientists and their contributions are included.
The included 5 terms and definitions are targeted at intermediate students and as a foundation to the scientific method. You may want to make the definitions more or less challenging, add images, or only use some of the terms. I have a column for links. These are completed by each individual student to help them remember the new term and definition. A time line project linking scientists with events found in the PP provides an anchoring activity.
Students apply the scientific method by identifying the Independent and Dependent variables, and constants of Redi’s experiment. This section identifies the importance of replicating experiments, what factors make an experiment valid, why it is important to collaborate and communicate with other scientists, and why it is often required to revise conclusions once new evidence is discovered.
This lesson is easily differentiated for the various learning styles found in the classroom. The 13 student prompts that follow the PP and keys are provided in MS Word (and PDF) formats. This allows for adjustments for differentiating to your students. You may choose to have students only write in key words, use fewer prompts, or in other cases students are given all prompts according to your teaching practices. The teacher key is helpful for absent student to use or when conducting additional research based projects.
