Curated OER
Anatomy- Excretory System
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...
Curated OER
Kidney Filtering
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...
Curated OER
Organ Systems
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...
Curated OER
Why is Excretion Necessary for Life?
Students 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.
Curated OER
The Skeletal 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.
Curated OER
Active Transport in Malpighian Tubules
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.
Curated OER
Virtual Fetal Pig Dissection
Learners 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...
Curated OER
Properties of Matter (Biomaterial Through Nanotechnology)
Students investigate friction between different surfaces. In this physics lesson, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.
