Activity #20: Circulatory System

Today students participated in activity 20 which was an introduction to the circulatory system. Students learned how the respiratory and circulatory system work together to provide oxygen to our muscles and our body. Students watched a movie about working out which explored how our muscles need oxygen and how lactic acid can build up. Students then answered six questions that were covered in the movie. Finally, students wrote a summary about main idea of the movie.
