Magnifiers Students experiment with the basic properties of lenses in this first activity. During discussion, they learn how magnifiers work, and attach names to the concepts they encountered during their investigation. The student use scientific methods during field and laboratory investigations. Collect information by observing and measuring.
Students examine an object through each of the hand held lenses.
After observing, they draw what they saw through the lens. During discussion, the teacher and students review the observations. They conclude with an explanation for the observed images through each lens. B. This curvature property is explored further with the demonstration using a jug of water. The jug and water together magnify along the curved surface of the jug.
