Seed germination investigation
Let's investigate which conditions affect seed germination!
Magnetic maze
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?
Investigate shadows
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.
Understanding physical processes
This worksheet will help your child to use first-hand experience to answer questions and to recognise that when things speed up, slow down or change direction, there is a cause.
Investigate shadows
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: build your own skeleton
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?
Understanding magnets: Make your own magnetic compass
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.
Understanding light reflection: Build your own periscope
Mirrors change the direction of light and reflect it. We can demonstrate this practically by making a periscope. Light is reflected from one object into a mirror and then onto the other mirror before reaching your eyes. Collect your materials and find out for yourself!
Understanding friction: Build your own balloon hovercraft
When a moving surface slides on a stationary surface it rubs against it, which slows it down. This is due to friction, a force which resists the movement of one object sliding past another. Understand more about friction with a fantastic practical project: make your own balloon hovercraft!
Experiments and science fun for KS1 and KS2
Beans, gingerbread men, ice, washing-up bottles and cocoa powder – that's all you need to demonstrate key KS1 and KS2 science concepts to your child at the kitchen table. Packed with simple experiments, fun games (Muffled Chinese Whispers, anyone?) and parent-friendly science explanations, our Experiments and science fun for KS1 and KS2 learning pack is all you need to make primary science come to life for your child.
Shadow puppet theatre
Cut out these dragon, fairy and owl shadow puppets to use in storytelling, while also learning about the properties of light and dark when a light source is blocked by an object.
Good and bad scientists
A list of statements for children to look through and decide which are true of good scientists.
Muscles and skeletons facts
A list of statements about muscles and bones that children need to cut out and then sort into 'true' and 'false' piles.
Growing diary data
A worksheet showing results of an investigation into how different soils affect the growth of plants.
Using information sources
A worksheet with spaces for children to research skeletons using various sources.
How are magnets used
A worksheet to encourage children to think about objects and whether they use magnets.
Pollination and fertilisation
A worksheet demonstrating the male and female parts of a flower and then explaining the process of pollination and fertilisation. Children draw pictures to show their understanding.
Investigate rock properties
Worksheet encouraging children to think about the properties of different rocks.
Predictions and conclusions: life cycles
A worksheet showing the predictions and conclusions of an experiment into life cycles. Includes questions to encourage children to use their investigative skills.
Light and dark vocabulary
On this worksheet, children need to match the words 'transparent', 'translucent', 'opaque' and 'shadow' with the correct definitions.
Seed dispersal
An activity to encourage your child to look for plants and think about the way the seeds are dispersed.
Light and shadows facts
This worksheet gives facts about light and shadows that children need to read and then work out whether they think they are true or false.
Investigate the principles of forces
This worksheet will help your child experience the basic principles of forces such as pushing/pulling, gravity, and friction.
Shadow spotting
This activity is a fantastic opportunity to introduce your child to the concept of light and dark.
