Resource. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.
- Go on a Light Hunt. Students look around the room to find examples of items (mediums) that transmit, reflect, refract, and absorb light. With small groups, I’ve also reviewed reflection and refraction with a light hunt.
- Hands-On Vocabulary Lessons. I adore these 2 lessons from my Hands-On Science Vocabulary. The first lesson is on transparency so that students can use those terms when discussing whether objects can reflect or refract light.
- Small Group Science. Sometimes, students need a little more support to understand what types of objects reflect light and which refract light. That’s where Small Group Science lessons come in!
- MUST-HAVE Observation Stations. These are an absolute must to help students master this standard! Observations Stations are activities that allow students hands-on experiences through 6 centers all focusing on a very specific concept.
- Transparent, Translucent, or Opaque? In the Can You See Through Me? lesson, students experiment with materials to see how they absorb, scatter, transmit, or reflect light.
- Casting Shadows. What happens when you walk down the street and the sun is in front of you? A shadow appears behind you! Objects that block light cast shadows.
- Reflections in a Mirror. In the Mirror, Mirror on the Wall... lesson, students experiment to see how reflective surfaces like mirrors change the direction of light.
- Colors of a Rainbow. In the How Many Colors in a Rainbow? activity, students use a pan of water, the sun, and sheets of colored paper to create rainbows.
Apr 29, 2020 · Learning Objectives After this activity, students should be able to: Explain the properties of light as related to security systems. Describe which objects reflect, absorb or transmit light. Explain light refraction as applied to rainbows that appear in nature. Identify a number of applications of radiation to science and technology today.
Feb 3, 2020 · Unlike reflection, the angle of incidence is not equal to the angle of refraction. This relationship between the angle of incidence and angle of refraction are known as Snell’s Law. Converging and Diverging Light. We can make light go in different directions using lenses. A lens is an optical device made of plastic or glass. When light passes ...
A magical idea for refraction: Place students into groups of 2 or 4. Provide each group with a coin, an opaque shallow bowl, and a container of water. Have one student place the coin in the center of the bowl and then step back until the coin in just out of sight. The other student then slowly, without splashing, pours water into the bowl.
