Year 3 Science worksheets
Cut along the dashed lines and assemble the skeleton. Use string and sticky tape to connect the bones, then hang the puppet pieces from a hanger
Look at these different word cards. Can you sort them into types of plant and into functions? Now shuffle the cards and see if you can match the different plants with possible functions.
Can you remember what transparent means? What about opaque? Use a torch to investigate different materials you can find around your house. Which ones allow light to pass through them (transparent)? Which ones block light (opaque)?
Look at this diagram of a skeleton. Can you name the different bones? How quickly can you label some of the key bones in the human body? Now see if you can colour code them.
Think about the different joints in your body and how they work. We often refer to your body as having 3 main types of joint – hinge, universal and ball and socket. Have you learnt about these before? If not, why not research these joints to see how they work. Now see if you can identify these different joints needed for each of these actions to be carried out by the human body.
Look at these picture cards. Can you sort them into two groups – those that are sources of light and those that are not?
Let's investigate which conditions affect seed germination!
Seeds disperse in different ways – through explosion, thanks to animals carrying them and via the wind. Use what you have learned about seed dispersal and your research skills to sort these seed cards using the sorting sheet on the next page.
Look at these picture cards. Can you identify the different types of rocks? What might these different types of rocks be used for? Can you match the different types of rocks to the correct name cards? Now shuffle the cards and have a game of matching pairs with a friend or adult. The person with the most cards at the end of the game wins!
Look at each of these cards and read the description. Can you draw a picture to match? Now cut out the cards and make your own plant cycle diagram. How would these pictures be different if you chose a different plant?
What foods you have eaten in the last 24 hours? Write them down in the table below. Can you identify the type of food you have eaten and the role it plays in your diet?
A sundial tells the time by using the position of the sun. This is how it works: the sun casts a shadow onto a surface marked with lines indicating the hours of the day. As the sun moves across the sky the shadow aligns with different hour-lines. Do you think you can make your own sundial?
Magnets come in all shapes and sizes; they also vary in strength. This experiment will test the magnetic force of a variety of different magnets.
How do you find your way around? Do you use maps? A satellite navigation system? Could you use a compass to direct you instead? A compass works using magnetism – the needle in the compass points towards the magnetic north. This helps us to find our way around. In this activity you are going to make your own simple compass!
Mix some paper clips up with some rice and put them in a closed, see-through plastic container. Using a magnet, how long does it take you to separate the paper clips from the rice without opening the container? Now set up a maze made of cardboard. Can you guide a magnetic ball or marble through the maze from the outside of box, using your magnet?
Find a glass jar. Put a selection of magnetic and non-magnetic materials inside. Close the jar and then, using your magnet, see if you can separate the magnetic materials without opening the jar.
Look at these statements about light and shadows. Can you sort them into those that are true and those that are false?
Be a shadow detective! Place an object outside and record how the height and width of the shadow cast by the object changes throughout the day. Record them on this sheet.
Boneyard Bill has fallen to bits! Can you help him by cutting out his different parts and putting him back together? Can you use the skeleton at the bottom to correctly identify the different bones Boneyard Bill is made up of?
The Earth has a weak magnetic field caused by the movement of molten iron in its core. The Earth’s magnetic field acts on a magnetised needle, pulling one end towards the north and the other towards the south magnetic pole. Understand more about magnets by making your very own magnetic compass from a polystyrene pizza base, a needle, a pin and a strong magnet.
