Fourth graders explore, analyze and identify the structures and order the process of the excretory system through a model or a diagram. They assess the names and locations of the organs involved in the excretory process, as well as...

Students investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry...

Students examine organisms that are composed of tissues, organs, and systems. They dissect a fetal pig and explore the assigned organs systems such as the skeletal, muscular, and circulatory organs. Students identify and explain their...

Students examine the energy dependence of active transport as well as te properties of specificity, competition, saturation, and inhibition. They anesthetize an insect and inject saline into the abdomen.

High schoolers describe and explain the function of each part of the excretory system. They discuss how the body uses the excretory system and identify diseases of the system.

Students identify bones off a skeleton during quizzes; assemble disarticulated skeletons; bird, frog and rat. They dissect frogs, remove the muscle tissue, and identify of bones.

Students use the internet to introduce themselves to the anatomy of a fetal pig. In pairs or individually, they work their way through a virtual dissection of a fetal pig while completing questions on a study guide. They also develop...

Students investigate friction between different surfaces. In this physics lesson plan, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.
