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

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.
Understanding light and dark
A worksheet designed to help your child investigate and understand light and dark.
Plan a scientific investigation
This worksheet encourages children to read through a plan of an investigation and decide where the problems might be.
Designing for a purpose
Let your child use their imagination to create a camouflage outfit, helping them explore ideas about designing for a purpose.
Planning healthy meals
Encourage your child to plan three healthy meals and then to do the opposite and plan three unhealthy meals.
Experimenting with forces
Develop your child's understanding of forces with an experiment to demonstrate the workings of a jet engine whilst encouraging scientific discussion.
Rocks and soil facts
This worksheet encourages children to read through the list of statements about rocks and soils and then decide whether they are true or false.
Understanding magnetic objects
Fun experiments to help your child learn about magnetism and magnets.
Select material properties
A worksheet to help your child think about the properties of different materials, with prompt words at the bottom.
Build a metal detector and learn about magnetism
Extend your child's understanding of magnetism by helping them build a metal detector.
Step-by-step investigation
Use this worksheet to help your child plan an investigation into the amount of light different materials will allow through.
A balanced shopping list
On this worksheet, children need to sort different foods into their groups.
Using scientific equipment
Use this worksheet to help your child plan an investigation into rock permeability.
All about rocks
A worksheet encouraging children to match types of rock (igneous, sedimentary, metamorphic) with their descriptions.
