Review: A good purchase. - Purchased for a four year old, but also enjoyed by an 11 year old.
Review: Excellent intro into science for young kids, but you'll need to buy consumable ingredients yourself - My daughters loved this science kit, and introduced the word "experiments" to my 4-year old daughter's vocabulary. Inside is a set of child-friendly science equipment (three large plastic test tubes, a 250ml beaker, a spoon, a child-friendly pipette, two test-tube stoppers, a funnel, three coloured lenses and a plastic base to hold it all). Also included is a booklet which outlines a series of experiments that you can try. These range from creating a baking soda volcano to making coloured "rain" in the test tubes. My children were a little too young to run the experiments themselves, so I happily stepped in to guide them through it. Note, that you will need to supply the consumable materials (generally household items that you have a good chance of having in your home, such as different food colourings, shaving foam, baking soda, vinegar, milk etc). The experiments are repeatable, and my daughters loved experimenting to get reactions. Even the neighbours kids watched over the fence in amazement. This is a fun introduction into simple to do science experiments and reactions that young children will enjoy whilst they're learning at the same time.
