This is a 10 page printable lesson. It has several pages of reading about the muscular system and it is not too technical so a middle school student between 5th and 7th grade should be able to understand it quite well with little help from a parent or teacher.
The lesson covers:
Skeletal Muscle Tissue
Cardiac Muscle Tissue
Smooth Muscle Tissue
The Names of some of the Skeletal Muscles.
Then there are 22 questions mostly open ended questions to answer.
The lesson should take about an hour to complete.
