As part of our 'I.D' topic, we learnt about classification systems, and how these can be really useful for scientists discovering new species. We classified the children of Elm class, by asking questions about their physical features. We sorted photographs as we asked questions about children based on hair colour, eye colour and other physical attributes, then put these into a classification tree diagram.
We were really lucky to have a trip to Sevenoaks School's Science Week! We had two workshops: one where we learnt about fireworks and the chemistry behind them, and one where we heard all about forces. It was brilliant and we learnt lots from the excellent demonstrations.
We learnt about chromatography in Science. This is the process of separating coloured inks or dyes. We used lots of different black pens to make marks on some filter paper, and then used pipettes to drip water on to them. It was really interesting to see which ink separated, and into which colours.
In term three, we are learning all about light within our science lessons. So far, we have learnt that we are able to see things due to light reflecting off them and into our eyes and that light travels in straight lines. This week we learnt how we see colour, and how different objects absorb different colours from the spectrum, whilst reflecting others (the ones we see.) To explore this further, we set up a circuit inside a polystyrene cup that had coloured sections. We covered the bulb with different colours sweet wrappers and noted which of the coloured sections we could or couldn't see.
In term 2, our topic is space. We learnt which planets were in our solar system, their order and their sizes. We used food to represent them, so we could understand their sizes in relation to each other better. Then, we went on to the playground and thought about how far away from the sun they each were. We imgained the sun was just 10mm in diameter, and that if this was the case, how far away each planet would be. We are astounded at the distances and what this meant in reality, when the sun's actual diameter is well over 1million km!
In Science we are learning all about forces! So far, we have learnt all about air resistance and friction and how they try to slow down, or stop moving objects. We have conducted experiements and investigations to investigate the effect of these forces, including finding out which shoe created the most friction and therefore had the best grip. We also learnt about levers and how these allow a small force to have a greater effect.
