Yesterday we had visitors from Medtronic. Marcia and John were engineers.
They were so nice and the things we did with them were so interesting.
They showed us a model of a heart and explained different things about it. They make devices to keep the valves of the heart open. We held the device and saw how they were able to shrink it with cold ice from a can.
We then made a cube using marshmallows and cocktail sticks. We tested then to see if they were strong, then we introduced triangles to see if they were stronger with this. It was so much fun!
Thank you John, Marcia and Medtronic!!
