The children in Kittiwakes Class have been learning about EVERYDAY MATERIALS in their Science lessons. We have really enjoyed this topic and we have learned so much about many different materials.
On Monday 18th March, we began conducting an experiment in our classroom. We got into groups of 4 to wrap and package chocolate Easter eggs! Our plan was to send these eggs through the post. We wanted to see if we had used our knowledge of materials to protect the eggs, so that when they were delivered back to our school by the postman, they were still in one oval piece!
We worked carefully and thoughtfully with the other children in our group to protect our eggs. We took the experiment very seriously and didn’t even try to eat any of the chocolate while we were working! There were seven groups cautiously wrapping the eggs.
Each group were given a different material to protect their eggs, such as bubble wrap, tissues, cotton wool pads, crepe paper, tissue paper, kitchen roll and wrapping paper. Three groups sent their eggs in padded envelopes and the other four used regular A5 envelopes. The children addressed each parcel themselves and added some decorations to the outside of the parcels to make them look nice!
We made predictions about how many of the eggs we thought would return to school without being damaged. We were reasonably optimistic with 8 of us thinking all seven would come back intact, and only one child thought they would all get broken!
Mrs Grocock zoomed the packages to Kenton Post Office on Monday afternoon, straight after our experiment! Most of the eggs (6 out of 7) came back to school the next day and the last parcel arrived on Wednesday 20th March.
During our Science lesson on Monday 25th March, we opened our parcels and discussed the results. Five of our eggs came back without getting broken! The most protective materials were bubble wrap, kitchen roll and wrapping paper. The least protective materials seemed to be the crepe paper and cotton wool pads. The padded envelopes offered extra safety. Oli, Lexi, Jenna and Ross (as well as Mrs Grocock and Mrs Radcliffe), correctly predicted that five eggs would not get broken in the post! These children took home one of the eggs for their excellent and accurate predictions.
We have worked hard this term, using our knowledge of materials to work scientifically, perform experiments and predict results. At home time on Monday 25th March, all of us were able to enjoy a yummy Cadbury’s Crème Egg (Kinder Egg or Haribo sweets) as a reward for all our hard work. We hope you like looking at the pictures of our Science experiment and that you have a very
