Friday 24 th April – Y 3 Science Hello everyone! This Science lesson moves us into our new topic of LIGHT. We have adapted the activities to hopefully make them more manageable at home, but still to include lots of hands on activities, to maintain their Science skills! Adapted from Twinkl resources.

We are really enjoying seeing the pictures and messages sent in to our Twitter

We are really enjoying seeing the pictures and messages sent in to our Twitter Page and School emails. Please label these Y 3 so we can make sure the Y 3 staff see them. It is lovely to see so many of you learning at home, and sharing this with us – we miss you all and can’t wait to get back into school with you. Best wishes The Y 3 team @elstonhallsch @palmerscrosssch @edwardeldersch @Goldthorn. Park

What is Light? • Can you name some things that give out light? • How does light help us to see? • What is dark? • How do mirrors work? • What is reflection? • How are shadows made? Our new topic is all about light. You will find the answers to all these questions, and more!

What do you already know? Create a mind map to show what you already know about light. Can you think of any questions you would like to find out about light?

What is a light source? A light source gives us light, and can be

What is a light source? A light source gives us light, and can be natural or manmade. Can you sort the objects into those that are sources of light, and those that are not? Make a table on a sheet of paper, and list them in the right group. Can you explain your reasons? There are some in there that may trick you!

Some of the cards were tricky to sort the moon, the window and the

Some of the cards were tricky to sort the moon, the window and the mirror are some examples. These objects look like light sources, but they are not!

The moon is not a light source because it does not make its own

The moon is not a light source because it does not make its own light. We can see the moon because light from the sun reflects off it (bounces off it) back to the earth.

The window is not a light source. It is an opening that lets the

The window is not a light source. It is an opening that lets the light from the sun or other light source into the room.

The mirror is not a source of light because it does not make its

The mirror is not a source of light because it does not make its own light. It reflects light from other sources.

Dark is the absence of light. (Try to learn that sentence if you can.

Dark is the absence of light. (Try to learn that sentence if you can. It’s a key part of our Y 3 learning) If there is no light from a light source, it will be dark. Think about times when it is dark, or places where it is dark. Which sources of light are absent, or switched off? Can we see in the dark?

You could do this activity with a family member. Find a bag which is not see through. One of you needs to put 5 or 6 items inside it, without the other person seeing. It is dark inside the bags, so you can not see what is inside. You will have to feel! The guesser needs to feel each object in turn, and describe it using Science language. For example, is it soft, hard, flexible…and then guess what it is. At the end, take out everything into the light and see how accurate you were. You could repeat this game and swap roles!

Was it hard to tell what was in the bags? It is much easier

Was it hard to tell what was in the bags? It is much easier to use our eyes to see, but for this we need light. How can we get light into the bags?

Let’s move on now to looking at reflective materials. If you need a short

Let’s move on now to looking at reflective materials. If you need a short break, take it now. Maybe grab a small snack or a drink. Right, part 2 now…

Click this link to watch this ‘The use of reflective materials for safety’ short film. https: //www. bbc. co. uk/bitesize/clips/zt cg 9 j 6 It is all about materials that reflect light. While you are watching, think about: What does it look like if a material reflects light well? Which colours do you think reflect most light? What are reflective materials useful for?

Light travels in a straight line. (Try to remember this) When light hits an

Light travels in a straight line. (Try to remember this) When light hits an object, it can be reflected (bounce off). If the reflected light hits our eyes, we can see the object. Light from the torch hits the object. The light is reflected from the object.

Some surfaces and materials reflect light well. Other materials do not reflect light well.

Some surfaces and materials reflect light well. Other materials do not reflect light well. Reflective surfaces and materials can be very useful: • Reflective strips on coats or bags mean you can be seen at night. They are also useful for fire fighters or builders who may work in a dark and dangerous environment. • 'Cat's Eyes' help drivers see the road by reflecting light from headlamps. • Mirrors let us see ourselves, and are also useful in cars, to allow drivers to see behind them. • Retro reflectors are used for road signs so that drivers can see the signs from their car. Can you think of any other uses?

In order to test the materials, you will need to make a reflection tester.

In order to test the materials, you will need to make a reflection tester. Attach a piece of white card to a torch: 1. Cut a hole in the centre of the card and push the torch through so that the card fits snugly around the torch without you having to hold it. 2. Shine the torch at the material you are testing. 3. If the material reflects light well, you will see the reflected light shine through the white card and light it up.

Once you have made your reflection tester, use it to test the different materials

Once you have made your reflection tester, use it to test the different materials you have been given. Order the materials – either into two groups or even from most reflective to least reflective!

What could I test? Anything such as a blanket, different coloured paper, clothes, tin

What could I test? Anything such as a blanket, different coloured paper, clothes, tin foil, a plastic bag, a mirror, the letterbox, a spoon, a baking tray, a bin bag, a coat. What do I think will happen? Predict which materials will be the most reflective. Try to explain why you think this. Test my materials one by one. To keep this fair, use the same light source and try to hold the material the same distance away. These variables need to stay the same. The only thing changing in this fair test will be the material. Record my results: You could make a simple chart to show what you find out.

Can you explain to a family member which material you found to be the

Can you explain to a family member which material you found to be the most reflective? Which was the least reflective? Think about why.

You could continue to think about the ways in which all reflective materials are

You could continue to think about the ways in which all reflective materials are similar. How do they look similar? How do they feel similar? Write down some ideas or research reflective materials, particularly linked to road safety with clothes and signs.
