After having done several years of Apologia science, I discovered these kits. They have made all the difference in the world for us completing each experiment. Supplies are packaged neatly and orderly. Module supplies are in their own labeled, ziplock bag. It tells you which products will be reused for later experiments. I now look forward to helping my children with their experiments because I know we'll have all the supplies. Too many times in the past we were missing an item or two and experiments failed more often than not.
This is our second time using this product. It is very convenient having everything you need right at your fingertips. The supplies are pre-packaged and labeled with the module number. The label even lists what to keep (if necessary) for future modules. I love the fact that I didn't have to pre-plan my lessons to make sure I had the right supplies on hand. I"m sure it would have cost more money to try to purchase these items individually, not the mention the aggravation of trying to find everything you need. I would definitely recommend this product to anyone who wants to save time and money.
I am very pleased with this kit. There are less expensive ones out there, but this one was worth the additional money. All the components are divided into modules, and even instructs the student when to pull things from different module bags. The time and effort it has saved us has been immeasurable. For us, it made the difference between science getting done or not!
