A Selection Pressure is the first in a three lesson series from Innovative Technology in Science Inquiry, that leads students to make sense of evolution. This lesson is introduced in the teacher guide (this is accessible once a login has been established) using a bug population and a set of questions as the phenomena. Students then engage in discussion that leads them into gathering data on a population of sheep. Students use an interactive simulation to gather data in order to create an explanation for evolution of population growth through natural selection under different conditions. This lesson is designed to be done individually, however could be done in groups depending on device availability. The teacher has the ability to set up a class and assign the lesson through a portal on the ITSI website (requires teacher to sign up for the website for free).
