I spent a lot of time evaluating the best educational subscriptions for my kids, 5 and 8, as a supplement to their education. I really loved the idea behind Scikids and decided to spring for the price along with the cheaper kiwi box. I am a professional scientist with a doctorate in pharmacology and this box blew me away! I loved the variety in the welcome box, amazing experiments from hatching and studying brine shrimp, growing plants to study roots to building a small moving toothbrush bug robot that lights loup to getting to polish and examine millions of years! In addition, there were petrified dishes, pipettes, everything you could need for all the experiments, education content, a great scientist journal and lab notebook with terrific formulas and other treats, there was even a cool robot eraser, crystal. The kids and I loved all of it.
