Here are some pictures of some images that came to mind when students read the descriptions of the fossils.
They even have some scientific names!
Same species... Different Student Images
They had to guess at a time period that has no frog ancestor fossils.
As a teacher, I really like how this lesson incorporated a literacy skill, such as imagination. This project gave students motivation to really understand and picture what the article was explaining. I could also assess students' comprehension of the article by their drawings of their flipbooks. I feel that it is difficult for science teachers to constantly incorporate authentic on-topic literacy in the science classroom on a consistent basis! What do you guys think? How do you incorporate literacy in your classrooms? I know that's a verrrrry broad question!
