We are all familiar with the the distinctive shape of the human heart, that wondrous organ at the center of our bodies. In fact, the standard image of the pumping human heart (let alone the simple cartoon version found on valentine's cards) as seen in media, advertising, and pop culture, is so ubiquitous that it's easy to forget that hearts come in a stunning diversity of shapes, sizes, and capacities. This set of classroom-quality comparative heart specimens helps to demonstrate nature's incredible variety while still showing that regardless of the size or species of animals, each heart shares a similar general structure with fascinating variations in the details.
As students pass this sturdy clear acrylic block around the classroom, they'll be able to observe 5 different animal hearts, and make note of differences and similarities between their structures. The block features a carp, frog, snake, pigeon, and rabbit, and each of these species thus serves as a representative for a different class of animal (fish, amphibian, reptile, bird, and mammal, respectively). The block can also be closely examined under microscope or magnifying glass to get a closer look. Excellent for collectors, or for use in the biology or anatomy classroom. Includes a numbered key to help identify specimens, and comes in a sturdy blue display box.
Note: Actual size of block is 6.4in x 3in x 1in
