Topic: The Heart

Objectives & Outcomes

• Students will understand how the heart works and the role it plays in the body.

Materials

• Colored pencils or crayons
• Construction paper
• Scissors
• Glue
• Cardboard
• Small pebbles or sand
• Markers or crayons

Warm-up

• Ask students if they know what the heart is and what it does.
• Ask them to raise their hand if they have ever had their heart checked by a doctor.
• Write down their responses on the board.

Direct Instruction

• Show students a picture of a heart and explain that it is a muscle that pumps blood through the body.
• Ask students if they know what blood is and what it does.
• Explain that blood carries oxygen and nutrients to the body's cells, and removes waste products from them.
• Ask students if they know how the heart works to pump blood through the body.
• Explain that the heart is made up of four chambers - two upper chambers called atria and two lower chambers called ventricles.
• The blood enters the heart through the right atrium, then passes through the right ventricle and is pumped out of the heart through the pulmonary artery and aorta to the rest of the body.
• Ask students to repeat the steps of blood flow through the heart with you.

Guided Practice

• Show students a diagram of a heart and label the four chambers and the main blood vessels.
• Ask students to work in pairs and match the names of the chambers and vessels to the correct parts of the heart.
• Have students use their knowledge of blood flow through the heart to answer questions on a quiz/worksheet.
• Ask students to share their answers with a partner to check for accuracy.

Independent Practice

• Give students a diagram of a heart with the four chambers labeled.
• Ask students to color in the chambers as they hear them mentioned during a short speech or presentation.
• Encourage students to pay attention and take notes on any additional information they hear about the heart.

Closure

• Ask students to share one thing they learned about the heart during the lesson.
• Review the functions of the heart and ask students to give examples of each.

Assessment:

• Observe students during the guided and independent practice activities to assess their understanding of the functions of the heart.
• Collect and review the drawings and explanations produced during the independent practice activity to assess their understanding of the functions of the heart.
