Tips From Teachers

“I used the video Lizards in an Evolutionary Tree paired with The Lizard Evolution Virtual Lab as we researched the concepts of evolution and natural selection in my 10th grade biology class. Both are excellent resources to apply major content topics and critical thinking skills that are needed on the Ohio state tests. They made evolution come alive and reinforced the idea that these processes really do occur in our world today.” -- Amy Kochensparger (Eaton High School, OH)
