I ordered this to go along with Apologia Science Zoology 2. It was just what we needed - not too much, not to little. The sand was clean and worked perfectly for the activity.
I ordered 2 of these. One for each of my children. Can be used on many different science projects. Saves time having it here at home on hand and not having to go search for sand or dirt the last minute.
The sand was clean, A+ all the way. This was so convenient to just add to my order for future school projects. Home Science Tools is the best!!
