Year 1

Year 1 held their own mini science week before the Easter holidays. We conducted different experiments that have us the opportunity to explore changes in state.  We observed solids melting in to liquids, liquids turning in to gases and even something that is a solid and liquid at the same time!

Skittles Rainbow

We placed skittles round the edge of a plate and added some warm water. We then observed how the colour dissolved out of the shell and made beautiful rainbows in the water.

 

Coke and Mentos

This was one of our favourite experiments. We went out to the field and save what happened when you added a mint to a bottle of Coke. We learnt that fizzy drinks contain carbon dioxide and adding the mint to it forced the carbon dioxide out of the drink really quickly causing a Coke explosion!

 

Cornflour Slime

This experiment had us entertained for a very long time. We mixed cornflour with water and then discovered that the mixture behaved like a liquid (you could pour it) and a sold (you could make it in to a ball) all at the same time!

 

Chocolate Nests

Our final experiment linked with DT and we make some chocolate Easter nests. We spoke about how the chocolate started as a solid but when it was heated it turned to a liquid.  We then observed how, as the chocolate cooled, it set back in to a solid.  A very tasty experiment!

We identified and then sorted a variety of animals in to different groups. These were: amphibians, birds, fish, mammals, reptiles and insects.

As part of our learning about seasonal changes we have been looking at how the weather is changing.  We made some wind spinners and took them outside to see if they worked.
