Science models are an amazing way to visually demonstrate science theories that are hard to understand using words only. This John N. Hansen 4D-Science Plant Cell Anatomy Model makes learning about plant cells both informative and fun. This science kit is also a 4-dimensional puzzle of a plant cell. It comes with 24 super-detailed colorful, plastic pieces that fit together to form the inner-workings of a plant cell. It comes with an illustrated guide book and a stand to keep this cell together to display on a desk or bookshelf. This 4-D science kit is recommended for kids ages 8 and up.
