I made a lung model!! Usually this time of the year, the kids make lung models with cups, straws and balloons. I demonstrated it in a video quite a long time ago. This year I decided to build also a big one!! This model demonstrates the functioning of lungs. Pulling out the plastic sheet (diaphragm) makes the pressure inside the jar (chest cavity) low down. This will cause the balloons (lungs) to expand and take in air. When the plastic sheet is released the balloons deflate again. #Chemistry #biology #physics #scientist #science #stem #techniciansofinstagram #Sciencetechnicians #Teachersofinstagram #Scienceteachers
