Product Information

use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them. Extra context can be provided with these What’s Going On videos: Seasons and Falling into place, which show the effect of the seasons on plants. With older children, you could take this discussion further with the Big Question Can you see the sunrise in space? and What if there were two suns? Shiny things is a useful Odd One Out activity to help explain how smoother surfaces reflect more light and are therefore brighter. What if we didn’t have mirrors? can help get your children thinking about the plus, minus and interesting of having to use less reflective surfaces in their everyday tasks. See round the bend is an excellent Problem Solver activity for children to try and apply their knowledge of light in a hands-on, collaborative and creative way. Children need to understand that we can see things because light travels from a source to our eyes or from a source to an object and is then reflected into our eyes. They should explore this by observing how light reflects differently from a variety of surfaces (including mirrors) and comparing the effect of each material’s properties. The hands-on nature of this topic continues when learning about shadows. Children should experiment with creating shadows using different light sources, objects of different shapes and sizes and changing the distance between the light source and object. It is also valuable to include objects that are opaque, translucent and transparent in this investigation so that children can compare the differences in any shadows created.

explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyesLearning about light begins with younger children thinking about the Sun as a natural source of light and learning how to safely observe and describe how it changes across a day and through the seasons. Older children will develop this further when learning about the Earth’s position within the solar system and why we have day and night and the seasons (see our Earth and space topic guide). Why not try going outside at different times on a sunny day and seeing how the Sun’s position has changed? This is also a great way to begin the conversation about sun safety. When doing any science related to the Sun, please refer to CLEAPSS or SSERC for advice on health and safety, and ensure children never look directly at the Sun.

use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye Exploring different sources of light and whether they are natural or man-made can be done through observation and discussion. Odd One Out activities, such as Shine a light and Sources of light, are a great way to get the conversation going with your class. The effect of daily and seasonal changes in light on how living organisms behave can be explored with the Odd One Out activity Spooky animals and the Big Question Who is overwintering in our school and why?. We recommend keeping it really practical when investigating this. You can focus on developing scientific skills of careful observation, comparison and identifying the properties of the materials that are the most/least reflective. Building on their earlier observations of the changing position of the sun, they can now develop this into an investigation by measuring the changing length and position of the shadows created by the sun’s movement. This is an excellent opportunity to focus on developing your children’s scientific skills of taking accurate measurements and recording data. If you are feeling particularly adventurous, you can even repeat this experiment at different times of the year to explore the seasonal changes in the position and strength of the sun’s rays.It can be valuable for children to identify and safely handle everyday light sources, as well as identifying sources found in less familiar contexts. For older children, exploring artificial light sources also provides an opportunity to link your learning about light with their understanding of electricity. Shadow shapes, Find your focus and Lightproof your secret den are good examples of how children can have fun exploring the relationship between light, shadows and the properties of materials. Light and time is another good video for helping children to understand how the position of the sun in the sky changes throughout a day, as well as for exploring the way shadows caused by the sun change.
