Investigating Spontaneous Generation Lab
Your students will:
|Can life arise from non-life? In 1864, noted French
scientist Louis Pasteur dispelled this concept, termed
"spontaneous generation", through one of science's most
famous experiments. Pasteur showed that microorganisms in a
sterilized nutrient broth did not develop spontaneously. Now
your students can recreate Pasteur's findings. They'll
compare the growth of organisms in flasks exposed to particles in
the atmosphere to those grown in flasks with special s-shaped
necks, exposed to air but not particulate matter.
- Study Louis Pasteur's classic experiment on spontaneous generation
- Investigate whether spontaneous generation can occur on earth today
- Define and recognize the characteristics of "life"
