Title: Locating the Skeleton

Grade Level: 2nd Grade

Duration: 45 minutes

Subject: Science

Objective: Students will be able to identify and locate major bones in the human skeleton.

Materials: - Large poster or diagram of the human skeleton - Small skeleton models or pictures of skeletons - Sticky notes or labels - Whiteboard or chart paper - Markers - Worksheets or activity sheets (optional)

Engage (5 minutes): 1. Begin the lesson by asking students if they know what a skeleton is and why it is important. 2. Show them a picture or model of a skeleton and ask them to share what they notice about it. 3. Write down their observations on the whiteboard or chart paper.

Explore (10 minutes): 1. Divide the class into small groups and provide each group with a small skeleton model or picture. 2. Instruct the students to examine the skeleton and identify any bones they can recognize. 3. Encourage them to discuss and compare their findings within their groups. 4. After a few minutes, bring the class back together and ask each group to share one bone they identified.

Explain (10 minutes): 1. Introduce the concept of major bones in the human skeleton. 2. Show the students a large poster or diagram of the human skeleton. 3. Explain that the human skeleton is made up of many bones, and some of the major bones include the skull, spine, ribs, arms, and legs. 4. Point to each major bone on the poster and briefly explain its function. 5. Use sticky notes or labels to mark the major bones on the poster.

Elaborate (15 minutes): 1. Distribute worksheets or activity sheets (if available) that require students to label the major bones on a human skeleton diagram. 2. Alternatively, you can create a class activity where students take turns coming up to the front and labeling the major bones on the large poster. 3. Walk around the classroom to provide assistance and guidance as needed.

Evaluate (5 minutes): 1. To assess student understanding, ask a few questions about the major bones in the human skeleton. 2. For example, you can ask, “What is the function of the skull?” or “Which bones make up the arms?” 3. Listen to students’ responses and provide feedback as necessary.

Extend: 1. To extend the lesson, you can have students research and create their own mini-books or posters about the human skeleton. 2. They can include additional information about the functions of each bone and any interesting facts they discover.

Note: Adjust the lesson duration and activities based on the needs and abilities of your students.
