In Sharks we have been looking again at algebra. We focussed this week on substitution – using what we have been given to work out other information – put values in to replace shapes or letters. The children have tackled many puzzles and have enjoyed the challenge. In science we used filtering to learn about reversible and irreversible change – it got a little messy but we ended up with some clean water (well cleanish!). We also conducted an experiment into changing materials – we used vinegar to change the properties of milk – making an almost plastic like substance.
