Ask A Biologist: Manduca Growth Experiment

The experiment can be used with students to assist them in uncovering how changes in temperature can affect the size and growth of organisms on Earth.

Global climate change is something that you have probably heard about. The temperature on Earth is always changing – it changes daily, seasonally, and over longer time scales, and it impacts not only the weather on Earth, but the climate as well.

Dr. Biology thinkingScientists want to know how these changes are going to affect life on earth. How will organisms and communities respond to these changes? Will changes in temperature cause these animals to shrink or get larger and even become GIANTS?

To study how temperature can affect how an animal grows, Dr. Biology has teamed up with the scientists in the laboratory of Dr.’s Jon Harrison and John VandenBrooks. Together, they started an experiment to see how warm and cool environments affect the growth of the Manduca caterpillar. In the end, you may find that some of these Manduca become GIANTS. Think you know which ones they are? Explore what the scientists found in their lab, or do it yourself! Click now to Enter the Lab.
