The main reason I did this was to assess how well they understand heart rate ranges when exercising at different levels of intensity. I felt that they had great practice during the last few weeks learning about and recording their heart rates while exercising, but until now, I haven’t really given them the opportunity to predict their HR and then compare their predictions to what their heart rate actually was.
For the most part, the students demonstrated a fairly solid understanding that heart beats per minute increases with level of intensity. However, some students either predicted heart rates per minute that were much too low or much too high which was an indication that I must review what heart rate ranges should be. I will provide the classroom teacher, Marina Gijzen, with the results from today to help initiate further discussion related to the circulatory system and heart rate.
As well, the blog post will serve to model what needs to be done with the other two grade 3 classes (John Rinker and Georgia Perry's classes) which will do the same lesson on Thursday. The video below will be seen by those grade 3 students and a discussion will take place after viewing this video. We hope that this serves to deepen their understanding of heart rate ranges and exercise. To see a few examples of student record sheets please view slide show below. All in all a very good lesson and a good indicator of what needs to be reviewed regarding the circulatory system and heart rate.
