FC: Muscles and Bones: Observations of our bodies while Jumping Rope By: 3rd grade researchers
1: By Sam Henry and Zachary Thomas-Kucerak Multiple joints moved up and down like hinges.
2: by Matt and Jaylen When I was jumping I noticed that my femur was bending. I noticed that my elbow was bending. I felt my patella moving when I jumped. I jumped off with my phalanges. My skull went forward when I jumped. My wrist was moving in a circle. My hand did not squeeze hard on the rope. It took a lot of bones to jump rope.
3: By Georgia and Ruthie When I was jumping I noticed that my Femur and my knee joint were working together to bend to jump over the jump rope. Also, my Radius, Ulna, and Humorous were working together with my elbow to turn the jump rope. My Carpals and my Metacarpals were twisting to turn the rope. My Phalanges were gripping the rope. My Torso didn’t work as much as my arms and legs did. My body moved a lot to turn the jump rope.
4: By Deva Holliman and Henry Green Jacks knee joint is a hinge joint so it is bending back a little bit. His tarsals and metatarsals are helping him make an aerodynamic posture.Jacks femur kept moving upward when he jumped.The carpals and metacarpals in his wrist was helping him turn the jump rope. Jacks upper arm was helping his lower arm bones because his arm needed to be straight in order for his carpals and metacarpals turn the rope. Jacks knee joint was bending to make his body have a spring position for him to jump. Jacks sternum was outward.
5: I noticed that I bent my femur when I was jumping. I also noticed that when I was jumping my phalanges were helping me swing the rope. When I jump my metatarsals pushed off the ground. My hinge joint was helping me jump rope. I noticed that my humorous was moving in a circle. My phalanges were helping me put less weight when I was jumping. My carpals were twisting. We observed that we were moving our tarsals.
7: By Madison Chandler and Isabel Seed When I was jumping, I observed I was moving two different joints at once (My ball-and-socket and my hinge joints). I also noticed that I was bending my knee (or my patella) when I was jumping. I also observed that my femur and my fibula were pushing of the ground to make me jump. My phalanges were the last thing to leave the ground and were the first thing to touch the ground.
8: By Ben and Samantha I noticed that my femur was bending when I was jumping. My phalanges were helping me swing the rope. My humorous was moving in a circular motion when I was swinging the rope. When I jumped my metatarsals pushed off the ground. While I was jumping I noticed that my tibia and fibula were joining with my femur and was bending. I observed my joints helping my bones move. My muscles were helping me hold the rope. And my rib cage was not moving.
