Subject: Human Biology; Skeletal System – Connecting Joints
http://www.eduref.org/cgi-bin/printlessons.cgi/Virtual/Lessons/Science/Anatomy/ANA0004.htm
Overview:
It is very important for students to understand the important of joints and cartilage in the human skeletal system. Without joints and cartilage humans would not be able to walk or move. Imagine trying to bend your arm and you could because it was bone on bone. It would feel like someone was rubbing two rocks together and trying to start a fire in your elbow. OOHHH!!!! Students will see the importance of cartilage and the purpose of joints in the skeletal system. Students will have hands on activity with clay and toothpicks to see how joints functions in the body.
NCSCOS
Competency Goal 4: The learner will conduct investigations, use models, simulations, and appropriate technologies and information systems to build an understanding of the complementary nature of the human body system.
Objectives
4.01 Analyze how human body systems interact to provide for the needs of the human organism:
- Musculoskeletal.
- Cardiovascular.
- Endocrine and Nervous.
- Digestive and Circulatory.
- Excretory.
- Reproductive.
- Respiratory.
- Immune.
- Nervous system.
4.02 Describe how systems within the human body are defined by the functions it performs.
Purpose: Students will name the different joints and understand how they work in the skeletal system.
Objectives:
- Students will be able to identify, list and locate five different joint types of the skeletal system.
- Students will use their communication skills to “teach” fellow students about the joints.
- Students will construct a clay and toothpick “skeleton” and label the joints.
Resources & Materials:
1-2 boxes of toothpicks
palm-sized piece of clay for each student
oversized drawing paper
markers/pencils
Day 1 Procedure:
- Discuss joints.
A. What is a joint? B. What do they let us do? C. Briefly discuss different kinds of joints – have students move their own joints as teacher points them out.
-
- Ball and socket – hips and shoulders
- Hinge – elbow and knee
- Sliding – vertebrae
- Pivot – neck, elbow, wrist
- Fixed – skull, pelvis
- Divide students into groups of four or five.
A. Each group pick a joint and order of presentation out of a hat.
-
- Each member write name on slip with joint name on it and return to teacher.
B. Choose a president, speaker, artist, note taker, and runner.
-
- the president will be in charge of the whole group and make sure that what needs to be done is done
- the speaker will be the main speaker during the presentation
- the artist will draw a picture or construct a model of the joint
- the note taker will write the outline and make the chart
- the runner will make sure the group has all the supplies needed
C. Discuss possible ways to find information – internet, Encarta, encyclopedia, library, books. D. Each group will organize information and present their findings to the rest of the class the following day.
-
- The presentation should be 5-7 minutes.
- Must include an outline (for the teacher) and a picture/chart of the joint and/or where it is in the body.
- Allow time for group work.
Day 2 Procedure:
- Break into groups and prepare for presentations.
- Presentations in order picked on previous day.
A. Outline should be given to teacher.
B. Instruct students to take notes during presentations.
C. Chart and pictures/models should be visible to all.
D. Leave time for question and answer segment after each presentation.
- Homework/Assessment
A. Construct toothpick and clay skeleton.
-
- Toothpicks can be broken into different lengths to represent the various bone sizes (about 10 per student)
- Clay will give the skeletons mobility and should be placed where the joints would be located (a palm- sized ball to each student)
- Give each student white construction paper and shoebox top to build skeleton on (easier mobility)
- Label ball and socket, pivot, hinge, fixed and sliding joints on skeleton.
