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.
Freezing and melting
Look at the cards and diagram. Can you complete the diagram to show the reversible changes of freezing and melting? Don’t forget to label the states of water too!

Examples of evaporation
Evaporation happens all around us. Can you describe what is happening in these pictures? What conditions can make this change happen? What other examples of evaporation can you think of?
Evaporation and condensation
Look at the cards and diagram. Can you complete the diagram to show the reversible changes of condensation and evaporation?
Electricity in our homes
Choose a room in your house and find all the things that use electricity to make them work. Can you find and draw the electricity source (the plug, switch or battery)? Remember: things that run off batteries also use electricity! If you are drawing light switches, add lines to show the wires which must run up to the light to make it work (even if they are hidden)
Does fire need oxygen?
In this experiment we will look at the effects of air (oxygen) on a candle flame. You will need an adult to help you with this one!
Create your own electrical warning sign
Look at electrical warning signs. What do you think they are trying to tell us? Now create your own electricity warning sign.
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?
Writing lists and using colons
Make a list of all of the different things in your living room. Use them to finish this sentence (and remember your colon!). Now make a list of all of the different things that might be in a wizard’s spell room. Use the list to finish the sentence below.
Venn diagram multiples investigation
Venn diagrams are a great tool to help you investigate whether a statement is true or false. Use the blank diagrams below to investigate the given statements. Give at least 10 examples before deciding whether the statements are true or false.
Using apostrophes for omission
Some of the apostrophes have gone missing from this passage. Can you add them back in? Then write each of the incorrect words in their uncontracted (unshortened) form in the grid below. Can you arrange the yellow letters to form word related to using apostrophes?
Using a tally chart to solve a problem
Penelope Pennywise is a very sensible (and scarily organised!) girl. She’s decided to make sure that she will have enough money each month to spend on her friends’ and family members’ birthdays. Here’s some information (some of it is important, some of it isn’t) about Penelope’s plan, and a list of birthdays throughout the year. Use the tally chart to help you work out how much Penelope will need to spend each month on birthdays. Will she be able to buy presents for everyone on her list?
Spot incorrect capital letters
Jennifer has gone a bit capital-letter-mad writing a letter about her interests and hobbies! Circle the words that shouldn’t have a capital letter, then find them in the wordsearch.
Sorting time connectives
Time connectives are words or phrases used in writing or speech to explain WHEN something is happening. Can you sort these time connectives from regular connectives?
Proportion explained
Proportion shows the amount of something out of a total amount. For instance, if I had 20 stickers and 7 of them were red, the proportion of red stickers would be 7 out of 20, or 7/20. Proportions are fractions!
