This lesson is made to use along with BrainPop Jr.'s video on fossils. However, it could be somewhat modified to use with another resource about fossils, such as a non-fiction text or another video resource.
This lesson includes discussion and writing prompts. It also provides examples for anchor charts: a vocabulary chart and a tree chart to create with your students while watching the video. These resources are then used to create an informational piece of writing about fossils.
This includes a 70-minute lesson that you could adapt as needed to make longer or shorter. It can be done throughout a day or spread out over multiple days.
Please note that I used this for my kindergarten class, but it could easily be adapted for up to 2nd grade, so CCSS are not in the lesson plan.
