During a science unit on light and how it affects things in our world, eighth-grade students created diagrams of mammal eyes identifying the parts and detailing how each part works to help us see. At the conclusion of the unit, students dissected a sheep eye and a cow eye. During the dissections, students were challenged to identify as many of the eye structures and tissues as possible. Many of the students were surprised by the large size of the cow eye. Lab experiences like these develop problem-solving and critical thinking skills as well as provide important exposure to reactions, materials, and real-world problems which makes hands-on learning experiences in science critical to the learning process.
