Objective

Students will learn that the muscles in the human body help the body move all of our body parts by ....

Big Idea

Students understand that muscles help our body move.

Introduction

10 minutes

I ask students to meet me at our meeting place rug so that we can learn about one more part of our bodies, the muscles.

We review our K-W-L chart from the unit.  We go over what we've learned and what questions we still have.  If we can answer any questions we fill in the chart as needed.

After reviewing, I ask the students to "show me their muscles". Then I ask if anyone can tell me what happened to their arm when the did that.

I listen for responses.

I explain to students that we have muscles in our body that lay on top of our bones.  Working together with our bones and or muscles, they all work together to help our body move.

Having students physically showing their muscles gets them to understand that muscles are really under their skin.  Being able to see for themselves that muscles are there makes the connection more apparent.

 

Guided Practice - whole group

20 minutes

I ask students to go to their seats quietly so that I can demonstrate how muscles work.

While the students are sitting at their seats, I show them a raw (but fresh) whole, chicken leg.  The skin should be peeled off already to see the tendons and muscles. 

I will explain the parts of the chicken leg so that students can make the connection to the human body.

I bend the chicken leg and have the students observe what is happening.  I ask the students to flex their arm again as I bend the chicken leg again. (When you bend the chicken leg, the muscle contract just as if you were watching/feeling your own arm muscle contract)

After doing this a couple of times, I ask the students to talk to their table partner, the student sitting across from them, about what they think is happening and how the muscles in their body are working.

As the students are talking, I walk around the room to help guide any students who may need help talking to their partner.

 

Closing

10 minutes

After listening to the conversations of the students, I ask them to freeze in order to gain back their attention. 

We close the lesson by talking about what things we can do to keep our muscles strong.  While we brainstorm a list, I record them on chart paper.  We talk about healthy foods and getting exercise.

This conversation will connect their learning from our lesson as well as what they have been learning in P.E. and Health classes.

After everyone has had a chance to contribute to the list, we go back to the K-W-L chart to fill in any information that we have learned in the lesson.  Since this is our last lesson for this unit, we make sure to complete the chart.

If there are unanswered questions on the chart, we will use time during our afternoon to do some research and answer them.  I feel that students deserve to have all of their questions answered.  It validates them as students.
