Bests & Worsts Reviews from Amazon

While I am not a chemist nor a volcano expert, I am a certified teacher. This kit provided hours and hours of quality time for my 4 year old, my six year old and myself. We measured ingredients, mixed solutions, made predictions, learned vocabulary, and discussed results. Can you think of many toys that can offer all of that? I thought the booklet that contained instructions was well-sequenced, with simple experiments followed by complex ones and with a helpful parent script. There were two drawbacks: the activities required direct parent involvement and sometimes a 2 hour wait time was required for "reactions" to happen
