Year 4 Scintillating Science Investigations

Through their Science unit, ‘Melting Moments‘ Year 4 have been investigating solids and liquids and how they can change state when they are heated or frozen. This week they investigated what happens to different liquids when they are placed in the freezer. Children worked collaboratively to observe what changes they could see and what may or may not have caused those changes to take place. Throughout this progress the children were working on developing their scientific vocabulary when they were sharing their observations and hypothesis with one another. Here are some of the things they found out…

“The hand sanitiser didn’t freeze because it has alcohol in it – alcohol is really hard to freeze. It needs to be in a freezer set at -114 degress Celsius!” (Sayah W, 4P)

​”The milk froze overnight. It froze as it is made up mainly of water. The milk is melting slower than the oil.” (Leo E, 4H) 

​”The oil turned a pastel-coloured yellow when it was placed in the freezer. It melted very quickly because the molecules in oil are different sizes, unlike the milk.” (Nicola G, 4P)
