We have been looking at changes of state and dissolving in science.
Here you can see the salt crystals that were left behind when we let our salt solution evaporate.
Below you can see how we learnt to measure the temperature accurately and found that the hotter the water, the more easily the substances dissolve. Other factors include the amount of water and whether it has been stirred.
We have been walking around the school grounds trying to identify the trees within. We looked at the shape, leaves, seeds and branches. Which aspect do you think it is best to use to identify a tree?
We have also been looking at the variety of shapes and colours of leaves. We have tried to order them using one feature.
