9 Christmas songs for starter activities for physics, biology and Chemistry

9 Christmas songs for starter activities for physics, biology and Chemistry

3 for each science. Songs that I have used for starter activities so the students to then either write their own Christmas song (KS3) or to write quiz questions on the topic (with a Christmas theme) to test their fellow students at the end of the lesson. Each song has 2 activities where the students have to sing the missing words (if they don't want to sing the whole thing) and each song has some check questions. objective: subject knowledge differentiation: all songs differentiated to at least 2 levels of difficulty; physics calculation questions come with 2 levels of hint there is a recording of each song embedded in the slides - please excuse my singing and feel free to delete this part
