As a result of USING this product, I found that it made science lessons more engaging and interactive for students. The United Scientific ELBM01 Electric Model is an excellent tool for demonstrating the inner workings of specimens to classrooms... While it is a bit on the pricey side for educators on a budget the investment is worth it for its durability and quality components. As an Industrial and Scientific product, it is a no-brainer for any science teacher looking to enhance their curriculum..
