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!
What is evaporation?
In this investigation you are going to see if water can move – or does it just change?
Food webs
When we look at habitats we often look at food chains to see the feeding relationships within them. Sometimes, though, more than one animal feeds off others. This is when we make food webs. Look at these cards. Can you cut them out and arrange them on the table with the arrows to show which animals feed off each other?
I hear with my little ear
Sit in a quiet place and close your eyes and listen really carefully. What can you hear inside the room? What can you hear inside yourself? Record the sounds you hear.
Condensation investigation
There is water in air! This simple experiment will help you to quickly see this.
Complete the water cycle
Look at this diagram. Where does the water come from? Where does it go? Can you complete the diagram using the labels below?
Changing states: solid, liquid or gas?
Materials usually exist as either a solid, a liquid or a gas. Look at the pictures on the next page. Can you cut them out and place them in the correct column to show whether they are a solid, liquid or gas?
Changing sounds: how does string length affect sound?
Sound is made by vibrations in the air. Many musical instruments use different length strings to make different sounds. This investigation will examine how the length of string changes the sounds made.
Changing liquids and solids investigation
Complete this investigation about changing liquids and solids and record your observations.
All about teeth
Human adults have up to 32 permanent teeth, which start to emerge when we are about 6 years old. Most people have all their adult teeth (apart from wisdom teeth) in place by the age of 12. Can you label this diagram of the different kinds of teeth?
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.
Using different sources to answer questions
A worksheet with prompts to encourage children to research different aspects of the topics they cover over the course of Year 5.
Make a telephone
Have fun with your child whilst they learn more about sound and its properties.
Changing sounds: vibrations
An activity sheet with ideas for things to do at home that demonstrate the connection between sound and vibrations.
Understand sound and hearing
Your child will have tons of fun doing this experiment whilst learning all about sound and hearing.
Changing state: condensation
A worksheet with activities your child can try at home to demonstrate the process of condensation.
Find facts about teeth
A worksheet listing questions for children to research about teeth.
Changing state: evaporation
A worksheet with pictures of the process of evaporation. Children need to write in the boxes what they think is happening in each picture.
Types of teeth
A cut-out and stick activity that will help your child to think about different types of teeth, how they are shaped and what they do.
Experimenting with pitch
Suggestions for activities to try at home to help your child investigate factors that affect pitch.
Circuits and conductors
A cutting out and re-ordering activity, where your child needs to match vocabulary on electricity with the correct definition.
