This afternoon, classes VW and
SC worked together to conduct a scientific investigation. They worked in house
groups in order to see if they could make plastic from milk and vinegar. The
children had to work together to write a prediction, method, results/
observation section and conclusion. Children had great fun watching the curds
form and then straining them through the sieve. The curds are called ‘casein’
and this forms when the protein in the milk meets the acid in the
vinegar, causing the quick separation we witnessed. The children moulded the
casein into different shapes- we will wait to see what happens over the next
few days. The children had lots of fun, although nobody appreciated the smell!
