Science Arm post
Not too long ago my class were learning about the muscle and bones in the arm.
My hypothesis was that it would work because there is a guide telling how to make it and if there is a guide i think they would have tested it so I have confidence.
What I learned was that the Radius is connected to the Bicep the Ulna is connected to the Tricep and the Humerus is connected to both the Tricep and the Bicep.
The materials I used where: cardboard, scissors, tape, paperclip, elastic band and balloons.
The steps I used where here.
The arm worked! The Ulna and the radius (aka the two smaller tubes) and the humerus were able to move the bicep and tricep (the balloons).
