This 3rd grade science curriculum has everything you need to cover science for the year! The units align with the NC Essential standards (3.P.1 - Forces and Motion, 3.P.2 - Matter, 3.P.3 - Energy Transfer, 3.E.1 - Earth in the Universe, 3.E.2 - Earth Systems, 3.L.1 - Living Organisms, 3.L.2 - Ecosystems), but I have added a little more to some units that I thought were lacking. Therefore, even if you don't live in NC, this bundle, or at least some of the individual units may suit your needs very
