In our first lesson we looked at how different animals need different foods to keep their bodies healthy and to give them energy. We learnt that animals are generally split into three groups depending on the foods they eat:
We then looked at the different food groups us humans need to keep our bodies healthy. They are:
We understand that these different foods help to keep our bodies healthy in different ways.
Then, we investigated sugar levels in different drinks. We discussed how foods and drinks with a lot of sugar in can be bad for us if we eat or drink them too often because if the sugar isn't used as energy straight away it is stored in our body as fat.
We found (unsurprisingly) that Coca Cola contains most sugar, with a whopping 10.5g of sugar per 100ml. That's two teaspoons of sugar per 100ml!
In Science today (Friday 5 October) we were learning about skeletons! We started the lesson by cutting out a skeleton (named Gary - after Gary Barlow (blame Mrs. Brady)) and putting the skeleton back together.
We then learnt about the names of some different bones in our body:
We learnt that our skeleton is there to protect our organs and to support our body.
Here are some photos of us with Gary!
On Friday 12th October, we learnt how muscles help our bodies to move by pulling our bones. We made our own model muscles and we found that when muscles are working they tighten (or 'contract') and get small and fatter. When they are not working (or are 'relaxed') they are long and thin.
We also found out that muscles work in pairs and when one muscle contracts, the other relaxes. We thought about how this works in our muscles and used the example of our biceps. When we flex our arms our bicep muscles are pulling our arm up and are short and fat, while our tricep muscles are long and thin. When our arms are straight, however, it's the other way around!
We also learnt the names of some of the muscles in our body, including our biceps, triceps, abdominals and quadriceps.
