I’m still going strong with these science worksheets because they’re so fun to make. I’m also getting a refresher on some of this stuff which I haven’t looked at in a long while.
As you’re talking about the respiratory system, you could also go into respiration and photosynthesis and save that for your plants unit. I always like to discuss how we breathe in oxygen and then exhale carbon dioxide as a waste product. I do like to tie this into photosynthesis because even though it is a waste product we have a symbiotic relationship with plants. We provide them with carbon dioxide while they produce oxygen for us.
The oxygen travels through our mouth or oral cavity, passes the pharynx, to the larynx then down the trachea to one of the bronchi, through the bronchioles into the lungs. Not pictured in the worksheets are the air sacs that are on the ends of the bronchioles called alveoli because they are too small to be pictured.
The diaphragm moves up and down as your inhale and exhale.
