Obtain, evaluate, and communicate information about the nature of light and how light interacts with objects. a. Plan and carry out investigations to observe and record how light interacts with various materials to classify them as opaque, transparent, or translucent. b. Plan and carry out investigations to describe the path light travels from a light source to a mirror and how it is reflected by the mirror using different angles. c. Plan and carry out an investigation utilizing everyday materials to explore examples of when light is refracted.
The Georgia Standards of Excellence, Science outcome S4P1 (Physical Science) for Grade 4 says: “Obtain, evaluate, and communicate information about the nature of light and how light interacts with objects. a. Plan and carry out investigations to observe and record how light interacts with various materials to classify them as opaque, transparent, or translucent. b. Plan and carry out investigations to describe the path light travels from a light source to a mirror and how it is reflected by the mirror using different angles. c. Plan and carry out an investigation utilizing everyday materials to explore examples of when light is refracted.” These 2 Fieldbook units teach it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Georgia Standards of Excellence, Science.
Earth and Sky at Home Grades K–5 · partly supports this outcome
Make a rainbow on the kitchen floor, grow crystals on a windowsill and build a cloud in a jar. Three classic home experiments that actually work, with the real science explained for grown-ups.
- Where do rainbows come from? 45 min, plus 10 min outside on a sunny day
Children split sunlight into colours with a glass of water, test whether the water is what makes the rainbow, and make their own rainbow with a hose mist. They finish able to explain that white light is a mix of colours that water bends apart.
Bouncing Light: Mirrors, Water and Colour Grades 3–5 · partly supports this outcome
Steer a beam around a wall with mirrors, find out why a pencil looks broken in water, and split white light into the colours hiding inside it. Three hands-on lessons on reflection, refraction and colour that build on shadows and work in any climate.
- How can a mirror steer a beam of light? 55–65 min
Teams shine a slit beam at a mirror, measure the angle it arrives and the angle it leaves, and find the rule for bouncing light. Then they use the rule to steer a beam round a cardboard wall, and test with a dark box how we really see things.
- Why does a pencil look broken in water? 50–60 min
Teams look at a pencil in a cup of water, make a hidden coin appear by pouring in water, and turn a water drop into a magnifying lens. Then they explain that light changes direction when it passes from air into water.
