IMSA Week 2 "Natural Selection- What it Takes to Survive"

IMSA Week 2 "Natural Selection- What it Takes to Survive"
 
We began with discussion about what "natural selection" & survival of the fittest" means. From there we made some predictions about what might happen to a population of bean seeds under some special conditions. Students were then given trays with different sized holes in the bottom and a bag of 4 different types of bean seeds. They were asked to place a certain population of each type of bean in their "environment" and shake it 15 times and then record what happened to their bean population. They then recorded data and doubled the surviving bean population and repeated the shaking and data recording. They repeated the doubling process for 6 "generations" and observed what happened to their bean population. From here we analyzed data using line graphs. We also had a nice deep discussion about natural selection and genetically engineering plants for survival.
