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 Tuesday 20th 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. It was a good job that the children were so careful, because Miss Lax accidentally broke the only spare egg that we had, before the experiment had even started!
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. Four groups sent their eggs in padded envelopes and the other three 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 very optimistic with 14 of us thinking all seven would come back intact, and nobody thought they would all get broken!
Miss Lax took the packages to the Post Office last Wednesday morning. Most of the eggs came back to school on Friday, but one didn’t arrive until after the weekend – this package was quite flat!
During our Science lesson on Monday 26th March, we opened our parcels and discussed the results. Three of our eggs came back without getting broken! The most protective materials were tissues, kitchen roll and wrapping paper. The least protective material seemed to be the tissue paper. The padded envelopes offered extra safety. Ollie and Mrs Radcliffe correctly predicted that three eggs would not get broken in the post! Ollie took home one of the eggs for his excellent prediction. The other six eggs will be enjoyed by all the Kittiwakes on Thursday afternoon at George’s special party! Yum J
We have worked hard this term, using our knowledge of materials to work scientifically, perform experiments and predict results. At home time on Monday 26th March, all of us were able to enjoy a yummy Cadbury’s Crème Egg as reward for all our hard work. We hope you like looking at the pictures of our Science experiment and that you have a very Happy Easter.
