Product Information
Full details
The Learning Resources Pumping Heart Model (LER3535) is designed for educators and students to develop a hands-on understanding of the human heart's basic functions and blood flow. Its key benefit is providing a visual and interactive way to explore how the heart and lungs work, particularly with the inclusion of colored liquids to illustrate oxygen exchange. A potential caveat is that it's primarily an educational tool and not a medically accurate simulation.

FAQs
What age group is this model best suited for?
The Pumping Heart Model is ideal for elementary and middle school students (ages 8 and up) as an introduction to the circulatory and respiratory systems.
What kind of liquid should I use?
You can use plain water mixed with non-toxic food coloring to represent different types of blood (e.g., red for oxygenated, blue for deoxygenated).
How many dye packs are included?
The model includes 10 packs of dye.
Does the model require batteries or power?
No, the model is manually operated using a hand pump and does not require batteries or external power.
Can I use this model to explain lung function?
Yes, the model includes lungs and allows for demonstrations of how blood circulates to and from them, illustrating the basic exchange process.
Is the activity guide detailed enough for a teacher with no prior knowledge?
The activity guide provides clear instructions and explanations suitable for educators to guide students through demonstrations and learning activities.
How do I clean the model after use?
Drain all liquids, rinse internal parts with clean water, and allow the model to air dry completely. Wipe the exterior with a damp cloth.
Troubleshooting
No liquid is being pumped.
Ensure the hand pump is securely attached and being squeezed with sufficient force. Check for any kinks or blockages in the tubing. Verify that the liquid reservoirs are adequately filled.
Leaks are occurring.
Inspect all tubing connections and seals to ensure they are tight and properly seated. If a connection appears damaged, contact customer support.
Difficulty in distinguishing liquid colors.
Use highly concentrated, non-toxic dyes. Ensure adequate lighting during the demonstration. Review the activity guide for recommended color combinations.
Model feels unstable.
Place the model on a flat, stable surface. Ensure all parts are correctly assembled according to the guide.
Pros and Cons
Pros
- Facilitates kinesthetic and visual learning for complex biological concepts.
- Engaging for students, turning theoretical lessons into practical exploration.
- Provides a clear, simplified representation of heart and lung function.
- Durable construction suitable for classroom use.
- Enhances understanding of circulatory system basics.
Cons
- Not a substitute for advanced anatomical models or medical training.
- Requires supervision for younger students during use with liquids.
- Effectiveness relies on the facilitator's ability to explain concepts.
- Limited scope in demonstrating all aspects of cardiovascular health.
Setup, Compatibility & Care
Setup: The Pumping Heart Model requires minimal setup. Ensure all components are present as per the manual. Add colored liquids (water with food coloring works well) to the designated reservoirs. Connect the tubing securely as indicated in the activity guide.
Compatibility: This model is designed for educational demonstration and does not interface with other electronic or mechanical systems. It is compatible with standard water-based liquids and non-toxic dyes.
Care: After each use, drain all liquids completely. Rinse the internal chambers and tubing with clean water to prevent residue buildup. Allow the model to air dry thoroughly before storing. Clean the exterior with a slightly damp cloth. Avoid harsh chemicals or abrasive cleaners.
