Slime Lab Viscous Adventure Kit (Explorer-U)

You can't beat these little kits for the value; there's a lot packed in each one for very little money! Every kit includes a project booklet, tools and equipment for several activities. While the booklet's activities are pretty basic, my favorite feature is that you'll be able to use the equipment for many other science experiments and demonstrations in the future! For example, the volcano kit includes a nice molded plastic volcano, a syringe, and plastic tubing. While you'll use up the baking soda and vinegar included right away, that volcano will last though many eruptions and will be a big time-saver if you really didn't have time to build or sculpt your own beforehand. Likewise, the Force Science kit includes a sturdy plastic track and a little cart which you could even use at the high school level to study friction, acceleration and force! It also includes a Newton's cradle to assemble, which is another nice bonus. The Geo Science kit includes a tiny divided rock box and specimens, plus a nice plastic model of the earth's crust. We also love Weather Science, with its included thermometer, evaporation chamber, blank weather charts, the parts to build a wind speed instrument and more! We think you'll be just as pleased at the quality and reusability of the components as we are! - Jess
