For a lesson about what is energy I have found some videos that could help to explain to grade four students the concept of energy. The link below will show the playlist that I have compiled:
https://youtube.com/playlist?list=PLA3Tl5K9OMv-pDyD2X4ssDc1Ofohm7NUi&si=7VLCsFDbqbdb_rrrAfter engaging students in a discussion about evidences of energy in the classroom and guiding them to the
concept of energy have them explore the above playlist to explain what really is energy and to clear up some misconceptions they may have about energy.
Students will then apply this concept of energy to evidences of energy they see in the environment. After which they will record their understanding of energy in their science journal.
