The Muscular System
Muscular System Intro Lab
Do not do any of the labs that you feel physically unable to do. We don't want anyone hurting themselves!
Learning Target
Form a conclusion about how muscles work in the muscular system
Success Criteria
diagram the muscular system
compare and contrast a flexed muscle vs. a relaxed muscle
assess different ways in which our muscles
Station 1 - Static Flex Observation
Station Directions: Observe muscles in a flexed position. Sit on lab table and hold a stack of 2-6 books on legs straight out.
Q: How did your legs feel when books were first added?
Q: How did your legs feel the longer you held the books?
Q: Why do you think your muscles felt like that?
Station 2 - Tendon Count
Station Directions: Flex different muscles in your body and count how many tendons we have.
Q: What is a tendon?
Q: How many tendons are in your body?
Q: What do tendons feel like?
Station 3 - Static Flex Test
Prediction: Does Oxygen play a role in muscle function? Why or Why not?
Station Directions: Do 3 different Wall Sits and time how long you could hold the exercise.
Trial 1 - breathe normally then do a wall sit.
Trial 2 - hold your breath while doing a wall sit.
Trial 3 - breathe excessively for 30 seconds to oxygenate blood then do a wall sit.
Station 4 -Dynamic Flex
Station Direction: Curl the dumbbell as many time as possible in 30 seconds. Do this 3 times and record how many you could do each time.
Q: How did your muscles feel after each trial?
Q: What bones were moving when you did the exercise?
Q: Was one muscle working more than any other?
Station 5 - Muscles Background Review
Station Direction: Read and answer the following questions. Base your answers on the various systems that we have studied.
Are there muscles in the Digestive System? If so where and what do they do?
Are there muscles in the Respiratory System? If so where and what do they do?
Are there muscles in the Circulatory System? If so where and what do they do?
What do the muscles do in all of these systems? Where are they and what do they do?
Station 6 - Interactive Muscular System

Pectorals
Deltoid
Trapezius
Biceps
Triceps
Quadriceps
