To learn how to build a respiratory system model, try these directions. Then add an information sheet and graphic organizer. They make teaching body systems as easy as 1-2-3!
Ms. Sneed Teaches the Respiratory System
Our favorite fourth grade teacher sat at the side table with her teaching partner. “Using models to teach science concepts is working out great in my classroom,” Ms. Sneed said.
Mr. Frank nodded. “Agreed. Let’s keep using them as we finish up our anatomy unit. We’ve already used body systems models to teach the circulatory, digestive, immune, musculoskeletal, and nervous systems. Now it’s time to plan for the respiratory system.”
Building a Model of the Respiratory System
“Let’s get started,” Ms. Sneed said. “As usual, why don’t you read over the directions. And I’ll gather the materials for the respiratory system model.”
Materials
Ms. Sneed walked to her science closet and opened the door. From it, she gathered:
- a plastic bottle
- two balloons
- scissors
- a utility knife
Steps
Next, as Mr. Frank read the directions, she built the model:
- Cut off the bottom of the plastic bottle.
- Tie the narrow end of the balloon. Then cut off the top third of that balloon.
- Feed the other balloon into the bottle top; pull the narrow end over the bottle top.
- Stretch the bottom of the cut balloon over the bottle bottom.
“Okay, let’s try it out!” Ms. Sneed exclaimed.
Mr. Frank continued with the directions: “To simulate breathing, pull down on the “diaphragm” (knot). The “lung” will inflate.
As Ms. Sneed pulled down on the knot, the inner balloon inflated. She shrieked with delight. “Wow!”
“Not the entire respiratory system,” Mr Frank said. “However, it’s a good simulation of the lungs”
Learning About the Respiratory System
He returned to the body systems unit. When he scrolled down, he found the corresponding information sheets. “This passage gives the main points about the respiratory system. Kids can read these to learn more.”
“Great,” Ms. Sneed responded. “Just like the informational texts for the other systems.”
Taking Notes
Mr. Frank scrolled further. “As they read, kids fill out graphic organizers,” he said. “Let’s use this one again. It asks them to tell about the respiratory system job and parts. Additionally, they compare it with an everyday system.”
“What do you think the respiratory system compares to?” Ms. Sneed asked.
“Good question.” Mr. Frank wrinkled his nose in thought. “Maybe an HVAC system. You know, the furnace sends air all over the building.”
“Additionally, the cold air return sends it back,” his teaching partner added.
Enjoy Teaching Body Systems
Ms. Sneed smiled. These human body activities allowed her to enjoy teaching a little more. After all, teaching the respiratory system with DIY models, information sheets, and graphic organizers made it fun and effective. Furthermore, it gave her life science curriculum a little punch.
