Did you ever have to twist and bend just to get it right? 3N did last week we made a muscle models.
The things we used are a rubber band, 2 paperclips. a rubber tube and 2 wooden sick.The rubber bands stand for the bicep, the 2 paperclips are the tendons, the rubber tube stands for the joint and the 2 wooden sticks are the bones and all together it is a arm model. This helps us understand how the arm contracts and relaxes.
