I teach 7th grade science and I use PBS LearningMedia because it’s easy to find videos and they have good supplementary materials, like good questions to ask the children to help improve the lesson.
Today I used a video on sound. The kids really liked it. They were able to get engaged with the video a lot more easily than if I were speaking at the board or if I were just using PowerPoints. They were able to see other kids in the video and understand what was going on with the sound better than if I were just explaining it.
