Levers in the Human Body

The human body is built around a sturdy frame called the skeleton. Muscles are attached to the skeleton and generate movement. Many levers exist within the skeletal structure.
There are 3 types of levers; first order levers, second order levers and third order levers.
Using iMovie or Explain everything;
           1.  Explain each type of lever and give an example of where that lever is found in the human body.
            2. Film the following actions; a) kicking a ball
                                                                b) lifting a weight using a bicep curl
                                                               c) leg lift on bench with weight
            3.  Explain and label the simple machine used to perform the actions. Make sure you use labelling on the images.
