Microorganisms on the Move
In this activity, students will learn how to prepare deep well slides for observing two types of microorganisms called Paramecium (a group of protozoa, or single-celled organisms, which move with cilia, so they are called “ciliates”) and Euglena (microorganisms which move with flagella, so they are known as “flagellates”).
Cool Craniums
In this activity, students will observe three “mystery” mammal skulls and compare and contrast the features of each skull. Students will learn the anatomical terms for skull features such as orbits, nasal passages, and foramen magnum. Students will learn how these features relate to physical characteristics or behaviors of each animal. Students will use their observations and recordings to attempt to identify each skull, and will discuss how these physical characteristics helped the animal survive in its environment.
