Let me teach your students for you! The Flipped Science Classroom is all about the short videos that come with my products! I sell the activity on tpt and always include the Youtube link with every activity. Each video, on average, is 3-6 mins long and briefly covers how to complete each activity, with examples. The intent is for the students to watch the video and complete the assignment with minimal extra effort for you. You can always expand on assignments but my students complete the work entirely from the videos.
