Lesson Plan of Bones as well as Muscles create Movement

General Science Grade IV

Students’ Learning Outcomes

·         Describe how bones as well as muscles operate together to create movement.

Information for Teachers

·         Muscles are exceptional parts of our trunk that tin post away contract as well as relax

·         When muscles contract they endure shorter as well as when muscles relax they endure longer.

·         When muscles (attached amongst our bones) contract, they clit bones as well as movements occur.

·         Different bones bring together together through joints.

·         Muscles must operate together inward coordinated groups.

·         Muscles groups create movements inward reverse direction.

·         A muscles contracts as well as shortens-it exerts a force

·         Counterpart relaxes.

·         Which muscles operate together to curvature as well as extend to your leg?

·         There are 3 types of muscles:

1.       Skeletal muscles are voluntary muscles, pregnant you lot accept to consciously displace them.

2.       Cardiac muscles as well as smoothen are involuntary muscles, pregnant you lot don’t accept to shout back close using them.

Charts/pictures of elbow articulation movements, textbook

Worm upwards Activity

·         Recall students’ previous noesis close bones as well as muscles.

·         Ask the students close the unlike movements inward their bodies.

·         Ask the students to stand upwards up as well as shout back close which bones as well as muscles were used inward this movement.

·         Ask the students to touching on toes, jump, run, touching on their ears as well as clap hands. Each fourth dimension inquire them to position the muscles as well as bones, responsible of the movement.

·         Explain that all the trunk movements are due to the movements of bones.

Development

Activity 1

·         Ask the students to experience the bones inward their arms as well as count how many bones brand total arm of human body?

·         Explain yesteryear making a unproblematic drawing on board, that in that location are 3 master copy bones inward arm; i inward the upper arm as well as ii inward the lower arm.

·         Ask the students to experience their ain arms as well as reckon if they tin post away experience ii bones inward their lower arms.

Activity 2

·         Ask the students to stand upwards up, as well as thence sit down down, as well as thence stand upwards up again. Ask them to moving ridge hands to state “Khuda Hafiz” allow them sit down down.

·         Ask: if bones couldn’t bend, how could nosotros move? (Accept all answer)

·         Ask the students to locate that expanse where ii bones bring together each other (i.e. joints). Point out that the 3 bones inward the arm come across at the elbow joint.

·         Show to the students the hinge inward the classroom door as well as window. Ask them to explicate its movements. Ask what would accept happened if in that location was no hinge.

·         Inform the students that the elbow articulation displace similar a hinge.

·         Ask few students to “walk” amongst stiff-legs as well as stiff-arms to a greater extent than or less the classroom trying non to curvature at whatever joint. Now inquire them what would hand off if nosotros don’t accept joints.

·         Ask them to do some tasks without bending the arm at the joint; similar writing on the board, drinking water, picking upwards their bags etc. thence inquire them how did they feel?

Activity 3

·         Ask the students to curvature their lower arms upwards as well as experience the front end side of the upper arm.

·         Explain that muscles contract for bending lower arm as well as thence motion occurs.

·         Ask the students how the upper arm muscles clit the bones of lower arm.

(Expected response:  muscles contract)

·         Ask them to curvature downward (straighten) their lower arms. Ask: what happens when you lot curvature downward your lower arm? What happens to the muscles?

(Expected response: Muscles stretch).

·         Inform the students that muscles operate inward pairs. The muscles on the front end side of the upper arm clit the lower arm bones thence the lower arm is bent up. The other muscles are acquaint beneath the upper arm. When they contract, they clit dorsum the lower arm bones thence the lower arm is straightened.

·         Ask the students to reckon the photograph of the muscles working at elbow articulation from the book.

Sum upwards / Conclusion

·         Bones as well as muscles operate together as well as are responsible for unlike movements inward our body.

·         Tell the students that inward adjacent lesson they volition acquire the mutual disorders of diverse parts of body.

Assessment

·         To assess the agreement of the students inquire next type of questions.

1.       Identify the contracted as well as the relaxed muscles inward a diagram of elbow articulation movements (show whatever flick of elbow articulation movement)

2.       Explain how muscles create movements at the genu joint.

3.       Describe the movements of your daily life inward which muscles as well as bones work.

Follow up

·         As the students to break the motion of their ain arms at abode or do this do amongst their sis or brother

·         Ask them to write their observations inward notebooks.

·         Ask them to displace their / other person’s arm at shoulder as well as elbow as well as write how much liberty of motion is in that location at each of these joints.
