What stores and transfers energy?
Energy cannot be created or destroyed, it can only be transferred from one store into another. In these pictures, which items do you think use energy? Which ones store energy? Do they all store/use the same type of energy? Cut them out and sort them into groups.
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!
Super scientist quiz
Quiz questions to encourage your child to think about how scientists work and why they do the things they do.
Reaching conclusions
A worksheet showing results of an experiment with questions underneath to consider.
Identifying good habitats
Try to find four different habitats that animals or minibeasts live in around your house. Make notes on how effective each of these habitats is.
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.
How fast do you breathe?
We breathe all of the time. Breathing is vital to ensure that oxygen is taken into our bodies and harmful carbon dioxide is taken out of our body… but how fast do we breathe? When does this change? Why? Complete the table and see if this helps you to answer these questions.
How does sound resonate?
Resonance is described as the intensification and prolongation of sound, especially of a musical tone, produced by sympathetic vibration. Now ask an adult if you can borrow some glasses to investigate how the amount of water in a glass can affect the resonance sound made.
Heart rate mix and match
When we exercise the muscles and organs in our body need more oxygen and energy. Our heart therefore has to work much harder. Look at these pictures of different activities. Can you cut out the pictures and the heart rate cards and match up each activity with the heart rate you think is correct?
Habitat adaptation
Plants, just like animals, are able to adapt to their environment – they have to do this to survive. Sometimes this is a short-term change; they can also evolve to change permanently. This investigation looks at how plants adapt to meet their need for light.
Gases everywhere
Can you use your knowledge of gases and research skills to find out how each gas is being used? Record your notes next to each picture.
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!
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?
Food experiment: reversible and irreversible changes
Ask an adult to help you conduct this simple experiment into reversible and irreversible changes. Heat each of these food items and see if the change is reversible or irreversible when the item cools.
Fatty foods investigation
Ask an adult to help you select different foods that you think may contain more fat than others. Carefully rub each food in turn in one of the circles. Label each circle so that you can see which food was in which circle. Leave the paper to dry. When dry hold it up to the light. You should be able to see which foods contained more oil and fat as this will be left on the paper!
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)
Drawing circuit diagrams
Look at these cards. Can you draw circuit diagrams using the correct symbols to match these descriptions?
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!
Dissolving salt investigation
In this experiment we will be investigating to see if the temperature of the water affects how quickly salt will dissolve in it.
Dissolving experiment
This is an experiment to help you learn about which materials will dissolve and which ones will not.
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.
