- Chart paper or notebook
Activities
-
Start by introducing the digestive system using the anatomy poster or diagram. Explain the different parts of the system and their functions.
-
Draw a large diagram of the digestive system on the whiteboard or paper. Ask the student to come up and label the different parts while explaining their functions.
-
Discuss the process of digestion step-by-step. Use the chart paper or notebook to create a flowchart or timeline of the digestive process. Encourage the student to actively participate in creating the visual representation.
-
Play a fun game of "Digestive System Match-Up". Prepare small cards with different parts of the digestive system and their corresponding functions. Shuffle the cards and ask the student to match them correctly.
-
Conclude the lesson by reviewing the main concepts and allowing the student to ask any questions they may have.
Third Grade Talking Points
- "The digestive system helps our body break down food into smaller parts."
- "The mouth is where digestion begins. We use our teeth to chew food and our tongue helps move it around."
- "The esophagus is like a tube that carries food from the mouth to the stomach."
- "The stomach is like a bag that churns and mixes the food with digestive juices."
- "The small intestine absorbs nutrients from the food we eat, while the large intestine absorbs water and forms solid waste."
- "The waste is then eliminated from our body through the rectum and anus."
