Learning Resources Pumping Heart Model

excellent teaching tool. The dye for blood is very realistic and easy to use. The 5 year old kids in class loved pressing the pump to fill heart with blood. Just wish the lungs didn't fill with blood!

Highly recommended

Great learning project for every age.

We bought this for my son’s project on the cardiovascular system. It worked perfectly to start, but started leaking after 20 kids tried pumping the blood.

This MIGHT be something for a classroom to use, but the red liquid does not "pump" anything, it just squirts around. You have to carefully mix red dye powder and add it (without staining anything) and add it to the toy. Then you have to be SUPER careful to not let children actually play with it or they will get the red dye all over your house. Then, to put it away, you have to take the tiny parts all apart with a tiny screwdriver, drain and rinse the red dye out of all the nooks and crannies and let it dry out for several days before you can put it back together. Totally not worth the hassle. Kids did not learn anything.

Love this! My children couldn’t stop playing with it. They began to ask more questions and looked at the veins in their firearms asking if the blood in their veins comes from their heart.

I'm not sure why this gets such terrible reviews. It's not entirely accurate but it's designed to give a simplified explanation of the circulatory system for children. My husband is a firefighter and my daughter (4 years old) is fascinated with his work especially during his EMT course. This provides a visual for her to see the blood coming into and out of the heart and to provide a gateway to questions she might not know to ask. She knows a heart pumps blood and has something to do with a pulse this provides her something to experience to link those ideas together. It has a small activity booklet. I have no idea if there are instructions in it as filling it is pretty self explanatory, just take the pump off fill it and pump the fluid in. If the dye packs are empty or dry, I haven't checked mine, some red flood coloring will suffice. I think people might be expecting a bit much of a toy.

Hard to squeeze that pump, and it's really hard to determine exactly how much liquid to put into the heart to make it right for kids to squeeze. That said, it is a great demonstration of the way the heart works and the 4 different chambers - just make sure you tell the kids that blood doesn't "pool up" in the lungs and heart chambers like it does in this demo. The kids really can't stay away from it.

Buenas calidad lo recomiendo

Great way to demonstrate how blood flows. Using it my first aid courses.

It's alright(ish) but quality isn't good. There's no spare or replacement blood and although its says don't use food colouring, the manufacturer replied to my request for spares and instructed me to use food colouring

Bello

The model work very well. My 4 year old son already know how the heart works in general.
