Title: Locating the Skeleton

Grade Level: 2nd Grade

Duration: 45 minutes

Subject: Science

Objective: - Students will be able to identify and locate the major bones in the human skeleton. - Students will understand the functions of the skeleton in the human body.

Materials: - Large poster or diagram of the human skeleton - Small skeleton models or pictures of bones - Whiteboard or chart paper - Markers - Worksheets or handouts with a skeleton diagram for each student - Pencils

Procedure:

1. Engage (10 minutes):
   • Begin the lesson by asking students if they know what a skeleton is and why it is important.
   • Facilitate a class discussion to elicit prior knowledge about the skeleton.
   • Show the students a large poster or diagram of the human skeleton and ask them to identify any bones they recognize.
2. Explore (10 minutes):
   • Divide the students into small groups.
   • Provide each group with a small skeleton model or pictures of bones.
   • Instruct the groups to examine the skeleton model or pictures and discuss what they notice about the bones.
   • Encourage them to identify any familiar bones and discuss their functions.
3. Explain (10 minutes):
   • Bring the students back together as a whole class.
   • Ask each group to share their observations and findings about the skeleton.
   • Write down the names of the major bones on the whiteboard or chart paper as the students mention them.
   • Explain the functions of the skeleton, such as providing support, protecting organs, and allowing movement.
4. Elaborate (10 minutes):
   • Distribute worksheets or handouts with a skeleton diagram to each student.
   • Instruct the students to label the major bones they have learned about on the diagram.
   • Encourage them to use the large poster or chart paper with the names of the bones as a reference.
   • Circulate around the classroom to provide assistance and answer any questions.
5. Evaluate (5 minutes):
   • Collect the completed worksheets or handouts for assessment.
   • Review the labeled diagrams to check for understanding.
   • Ask a few students to share their labeled diagrams with the class, explaining the functions of the bones they have identified.

Extensions: - For advanced students, provide additional information about the different types of joints in the human body and how they allow movement. - Have students create their own skeleton models using art supplies or recycled materials. - Encourage students to research and present information about the skeletal systems of other animals.

Note: Adjust the duration of each section according to the pace of your class.
