After studying the Nervous System and the Circulatory System, we continued our journey through the human body by heading to the Respiratory System. We began by viewing... ...the "Once Upon a Time..." videos about breathing. Part 1 Part 2 Part 3 (I love the visual notes Baby Girl created while we watched the videos!) *** On another day during our study about the Respiratory System, we completed the Breathe In, Breathe Out activity found in our From Head to Toe AIMS Science Book. We created a model of the lungs using a few simple materials from around the house... *2 liter bottle (cleaned out and label removed) *Duct tape *2 balloons *2 bendable straws *Modeling clay 1. Take the straws and bend the ends of them at an angle. 2. Stretch out the balloons. 3. Attach the balloons to the ends of the straws with duct tape. 4. Place the straws back to back to form a "Y" shape. 5. Tape the straws together. 6. Place a good sized ball of clay towards the straight ends of the straws, leaving the the holes open. 7. Carefully place the straws into the bottle and secure the clay around the opening of the bottle. Then give the model a test drive... We tried our model out a couple of different ways. First the kiddos blew into the straws... ...and then they squeezed the outside of the bottle. Totally-cool. *** Finally, we recreated a visual image of the lungs following the instructions and printables from Relentlessly Fun Deceptively Educational. What a breath of fresh air these activities were! ;0) *** Up next in our Human Body study- the Digestive System... *** Linking up with Science Sunday...
