This half term in Science, Year 5 have been investigating the properties of materials.
We have conducted many experiments, including:
- Mixing cornflour and water
- Comparing and grouping together everyday materials based on their properties (hardness, solubility, transparency, electrical conductivity, thermal conductivity and their response to magnets).
- Investigating what changes are reversible? - melting chocolate - freezing water - creating salt solution
- Showing that dissolving, mixing and changes of state are reversible changes.
- Understanding what are filtering, sieving and evaporation - rice and water in a sieve - coffee and filter paper - evaporating salt solution
- Investigating what changes are irreversible? - cutting open an apple (oxidation) - bicarbonate of soda and vinegar (creates CO2) - coke and mentos (creates CO2) - turning cream in to butter
They have been recording their experiments in their books with
- hypotheses and predictions
- results tables
- conclusions
They have also converted the results of one test into graphs on laptops in a Computing lesson.
Below are just a few photos from Hawthorn class' experiments.
