Year 5 – Science

Year 5 science

The children have been busy this half term learning about the properties of materials in science. We have discovered what a property and a material is and have been investigating how different materials change. The children have identified the difference between a mixture and a solution had a go at separating solutions and mixtures using sieves, filters and by boiling hot water. We have also been experimenting with reversible and irreversible changes. We have discovered that materials can change and then be changed back, such as ice melting back to water. During this investigation we made lava lamps using oil, water and alka seltzers, which demonstrated how other changes are irreversible, meaning the materials cannot be easily changed back.

Through discussion and investigations that the children have carried out themselves, they have developed their scientific vocabulary and their skills and impressed us with their ideas and explanations.
