Wow! Captivation, Inc. sent us their intriguing Teaching Tank and three "how-to-do-it" books (called Discovery books), absolutely full of science experiments. To me, science is somewhat difficult to teach. Unless you do something hands-on, it seems a struggle to get children to learn scientific principles. I don't care for the idea of referring to a science experiments book only. The Teaching Tank is different. It draws you in immediately. The experiments you can do with it are phenomenal - children get wide-eyed, as they see, smell, hear and feel chemistry, physics, and biology. You must check this out! My husband and our kids easily put the tank together and then got busy browsing through the Discovery books that come with this to joyfully figure out just which experiment to do first. They could not decide! Teaching Tank has so much to offer! Grow plants in crystals right inside the tank. Observe wiggly little living creatures in the tank - ew, ew, ew (but so fun!)! I could go on and on and on, but go see it for yourself! For sure, kids of all ages will get excited about this huge kit. Get your homeschooler a Teaching Tank, and watch them gain a whole new love (and understanding!) for science!
