“The best part was reading what the students wrote about afterwards...very impressed with what they learned!”

“My students loved this lesson! They enjoyed learning what the human heart actually looks like compared to the heart shape they usually see. By the end of the day, my students were explaining to other students (who missed the lesson) what it means when the heart beats--blood is being pushed through the arteries. Amazing lesson!”
· Leanne · Teacher
“The best part was the class pumping the paper heart and then getting tired. They really understood how hard their heart works and talked about how important it is to take care of it. They loved making the Valentine to their heart after that. It was very powerful motivation to be healthy for them. Thank you!”

Thanks so much and Happy Valentines Day Doug!!”
