Drawing circuit diagrams
Look at these cards. Can you draw circuit diagrams using the correct symbols to match these descriptions?
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)
Evaporation and condensation
Look at the cards and diagram. Can you complete the diagram to show the reversible changes of condensation and evaporation?
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?
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!
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.
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?
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!
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.
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.
