Educator Guide: Types of Reproduction and Climate-Helping Bark Microbes

In atmospheric chemistry, an equilibrium will develop as the system balances gains and losses in important molecules. Calculate the role of bark-dwelling microbes on the overall concentrations of atmospheric methane, all while answering questions about how a new understanding of microbial diets might suggest paths to a more sustainable future.

In this lesson, students will compare asexual and sexual reproduction while analyzing the rate that offspring are created. Then, they’ll explore how the elm zigzag sawfly is spreading across North America, the threat this poses, why this case is different from other insect invasions and what concerned citizens can do.
