Muscle Contraction WebQuest
Introduction
Welcome: Skeletal Muscle Contraction-Spinach Connection
Description: Learn the anatomy and physiology of a muscle contraction using
animations. Project-based assessment concludes the WebQuest.
Grade Level: 9-12
Curriculum: Anatomy
Task 1: Review of muscle contraction concepts.
Watch the following animations in order and then answer the questions that follow.
Neuromuscular junction
1.
What causes voltage-gated calcium ion channels to open?
2. Calcium moving into the neuron causes vesicles to release a neurotransmitter. What’s the name of this
neurotransmitter?
3. What is the name of the enzyme that breaks down Ach?
Action Potentials and Muscle Contractions
4.
Explain what you think a neuromuscular junction is.
5.
What is the name of the protein that covers up the myosin binding sites on actin?
6.
Create an analogy that describes the role of troponin & tropomyosin.
7.
How would you describe a cross-bridge?
Breakdown of ATP and Cross-Bridge Movement during Muscle Contraction
Muscular System, Sliding Filament Theory 1
8.
What is the connective tissue that connects muscle to bone called?
9. What is the connective tissue that separates bundles of muscle fibers?
10. What is the connective tissue that separates individual muscle fibers?
Muscular System, Sliding Filament Theory 2
11. Why do you think the mechanism of muscle contraction is referred to as the “Sliding Filament Theory”?
12. Do muscles get longer or shorter when they contract?
Task 2: Summary animation with self-quizzes.
Watch the following animation and answer the three questions below by completing the quiz part of the tutorial.
Muscle Contraction Summary & Quiz
13. The sliding filament theory states that, during muscle contraction and relaxation,
a. Actin & myosin filaments shorten, then lengthen
b. Actin & myosin filaments change positions relative to one another
c. Troponin & Tropomyosin slide past one another
14. During muscle contraction, calcium ions bind to
a. Troponin
b. Tropomyosin
c. Actin
d. Myosin
15. After a myosin head has performed a power stroke, it must first bind to ________ in order to perform another
power stroke.
a. Actin
b. Troponin
c. Tropomyosin
d. ATP

Popeye Cartoon -theme song
Using your knowledge of muscles and how they work,
explain in 250 words or less the reason for Popeye's
obsession with spinach. This should be typed using
12 pt Arial font, double-spaced, printed and stapled to
your WebQuest questions which will be turned in with your presentation.
Task 4: Project/Evaluation
In this WebQuest project, you will choose one of the following projects to complete.
Option 1: (1 to 2 members in a group) Construct a working model to demonstrate the sliding filament theory and be
able to identify the parts and demonstrate your model to the class without notes or cue cards.
Option 2: (3-5 members in a group) As a group, act out a play demonstrating what happens at the neuromuscular
junction. Include up to the creation of an action potential that initiates muscle contraction. You may use props and
costumes but no notes or cue cards.
Option 3: (1-2 members in a group) Write a graphic novel (comic book) with the target audience being students in
grades 5-8. Explain how the muscles are put together and how they work. Make sure to include illustrations with your
story.
Option 4: (1-2 members in a group) Create a poster, Prezi, PowerPoint, or some other presentation that shows the
steps of muscle contraction. You will be presenting this information to the class without notes or cue cards.
