A drug given to mice with Alzheimer’s quickly improved memory deficits and behavior resulting from the disease.
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.
The human eye may be only about the size of a ping-pong ball, but it is an amazingly complex sensory organ that requires all of its components to function properly in order for a person to have optimal vision. Each part of the eye works together with the others to process light rays into electrical impulses, or messages that are transmitted to the brain. The brain interprets this information and allows us to be aware of our surroundings. Our eyes and brain are able to capture and interpret millions of images a day, shaping our view of the world.
