Description
Two mirrors in one! This compact and easily stored mirror is convex on one side and concave on the other. The concave side is front-surface - perfect for a physics unit on light and reflection. Curved mirrors are all around us - in stores, telescopes and even in rear view mirrors. Ask your students to explain exactly why "Objects in mirror are closer than they appear", then, use our mirror to explore, experimentally, light ray diagrams and the science behind magnification. This mirror features reflective coatings on the outside for exceptionally true reflections as well as beveled glass edges, for safety, which are NOT sharp to the touch. The mirror is 75 mm in diameter with a focal length of 200 mm.Reviews

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.| Elementary | Middle School | High School | ||
| 1-PS4-3 Students can use Convex-Concave Mirrors to conduct an investigation of how different materials affect the path of light. 2-PS1-2Students can use these in an investigation where Convex-Concave Mirrors and other different materials are tested with analyze data and determine which materials have the properties that are best suited for an intended purpose. 5-PS1-3Students can use Convex-Concave Mirrors to make observations and measurements to identify materials based on their properties. | MS-PS4-2 Students can use Convex-Concave Mirrors to develop and use a model to describe how waves are reflected, absorbed, or transmitted through various materials. | HS-PS4-1 Students can use Convex-Concave Mirrors to conduct investigations and use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media. HS-PS4-5Students can use this Mirror to conduct investigations about technological devices use the principles of wave behavior and wave interactions with matter to transmit. |
Students can experiment with a variety of materials to determine which ones are best suited for an intended purpose such as seeing around a corner. Concave mirrors narrow the scope of vision, whereas convex mirrors broaden the scope of vision.
5-PS1-3Students can use Convex-Concave Mirrors to test for reflectivity when shinning it with a light or laser.
1-PS4-3 andHS-PS4-1
Students use Convex-Concave Mirrors to test the Law of Reflection by using a flashlight or laser pointed at the mirror and measuring the angles off the mirror. Placing a concave and a convex mirror side by side with an item to be reflected shows how the light or reflection can be bent due to the surface shape.
MS-PS4-2Students can use Convex-Concave Mirrors and other objects during investigations about what materials allow the light from a laser to pass through, be absorbed or reflected.
