So far, since we started the Human Body System unit in October, we've covered these system:
Nervous, Respiratory, Circulatory, Skeletal, Muscular. Bones as Levers was a short lesson on where levers can be found in the skeletal/muscular system.
Digestive System/Nutrition is what we are currently covering.
Systems we will cover in the near future:
Reproductive/Endocrine, Integumentary, Excretory.
Once we are done with the body systems and had a test over the above systems, including Digestive, frog dissections will be done. More info to come on frog dissections.
