Dark is the absence of light. We cannot see anything in complete darkness. Some objects, for example, the sun, light bulbs and candles are sources of light. Objects are easier to see if there is more light. Some surfaces reflect light. Objects are easier to see when there is less light if they are reflective. The light from the sun can damage our eyes and therefore we should not look directly at the sun and can protect our eyes by wearing sunglasses or sunhats in bright light. Shadows are formed on a surface when an opaque or translucent object is between a light source and the surface and blocks some of the light. The size of the shadow depends on the position of the source, object and surface.  \nOpportunities for science capital:  \nPotential for a class trip to for a ‘Light and shadow workshop’ at We are the Curious.  \nPart of science capital includes scientific media consumption-documentaries, reports etc. So, I have added a couple of links which give daily science news for children. Checking in on these every now and then would be beneficial to help children see science in the wider world.  \n[https://](https://)  \n[www.sciencenewsforstudents.org/](www.sciencenewsforstudents.org/)[ ](www.sciencenewsforstudents.org/)[https://](https://)[ ](https://)[www.sciencejournalforkids.org/](www.sciencejournalforkids.org/)  \nAssessment:  \nBy the end of this topic, pupils will be able to recognise that we need light in order to see things and explain that dark is the absence of light; explain that light is reflected from surfaces, explain why light from the sun can be dangerous and how we can protect our eyes; explain how shadows are formed and describe patterns in the way that the size of shadows change.  \nWhen working scientifically, pupils will be able to use straightforward scientific evidence to answer questions; record findings using tables, drawings and bar graphs; gather and record data to answer questions and use results to draw simple conclusions.  \n\n| Year 3: Light |\n| --- |\n| SCIENTIFIC CONTEXT: Physics |\n\n|  |\n| --- |\n| Theme 1: The dark |\n\nStarter:  \nKWL grid  \nClass discussion: W","cbCaibutvSVBGOS9","https://ap.wps.com/l/cbCaibutvSVBGOS9","pdf",1367458,"English","# Year 3: Light\n## Scientific context: Physics\n## Key vocabulary and working scientifically\n## Key questions\n## What I need to know\n## Theme 1: The dark\n## Theme 2: Reflector or light source?","[{\"question\":\"Why can we see objects in light but not in complete darkness?\",\"answer\":\"We see objects because our eyes can sense light.
