Year 3 Tooth Decay Investigation

As part of our science topic this half term, we have been learning about our teeth. The children are now teeth experts and know the names of each type of tooth as well as what their “job” is. We also spent some time talking about how important it is to brush our teeth and why we need to do it every day. We found out what happens to our teeth if they don’t get cleaned – the build-up of plaque reacts with the sugars in food to create an acid that attacks the teeth!

Last week, we conducted an experiment using hard boiled eggs to act as the teeth – each egg was placed in a different liquid (coke, orange juice, vinegar, black current squash, milk and water) and left for a week to see if it had any effect on the shell.

This week we have started our observations of the eggs. We were all quite shocked at the results! The vinegar decayed the egg the most by entirely disintegrating the shell leaving us with a squishy egg, the coke cracked and discoloured the egg quite badly,  the orange juice left a slimy skin all over the shell, the squash stained and cracked the shell and the milk and water had little effect. This led to very interesting discussion and some good ideas for their conclusions. What an interesting and fun experiment, fantastic work Year 3!!

Home on the range

Year 4 have been busy starting the construction process of their Wild West inspired prairie schooners. They have used their designs to help guide decorating and shaping of their carriages and are excited to see the final products!

Year 3 Stadium Visit

What a fantastic time the Year 3’s had visiting the Liberty Stadium today.  In the morning, the children took part in a healthy eating workshop where they found out lots of important information about different food groups and what types of food professional rugby players eat to keep themselves fit and healthy. After listening carefully to the information,  they were challenged to make their own healthy sandwich. They had lots of different ingredients to chose from but they had to pick really carefully to ensure their sandwich had the correct proportion of carbohydrate, protein, dairy and fat as outlined on the ‘Eat Well’ plate. What a brilliant effort boys and girls, your sandwiches looked amazing! I hope you enjoyed eating them.

In the afternoon, the children were given a tour of the stadium. They thoroughly enjoyed this experience and loved having the opportunity to see what it was like to be in the shoes of a professional rugby player, even if it was just for a day!

Outdoor Learning

Year 4 got outside this afternoon as part of their science investigation into filtering and cleaning water. They collected shells, stones and rocks and have planned their investigation ready for later in the week.

They also completed some difficult literacy challenges, including using a cypher to decode a word, and worked on drawing and interpreting graphs and charts.

International Learning

Year 4 were incredibly lucky this afternoon to have taken part in a Skype history and geography lesson with a teacher in Wyoming, USA. They learnt all about the state of Wyoming and how it is a state of “firsts” in America. They also got to see artefacts and interesting objects related to the Plains Indians and other people who lived there in the past (including some shocked faces when they saw a water bottle made out of a bison’s bladder!). They learnt about the mountain men who trapped beavers, then used the pelts to make hats, and learnt about the process of felt making and how hatters were affected by mercury poisoning.

They listened brilliantly and asked lots of questions about what’s they had learnt about. We’re looking forwards to another lesson from America later on in November!
