Remind students they will be able to identify and describe 3 types of rocks and why they are important.

Review & Ask if they have any new information to add to their Alpha Box Chart.

Explain to students that they are going to watch the Rocks & Minerals video from BrainPOP Jr..  Create Google Doc.  titled, Video Notes, so students can keep track of new info learned while watching the video.

Review the shared Google Document, Video Notes, with the class to see if they need to add any new key words to their Alpha Box Chart.

Optional: Take the BrainPOP Jr. quizzes with the class at the end of the video
