Since April 1st, Robins have been learning about condensation and evaporation.
As scientists they developed Setting up simple practical enquiries, comparative and fair tests.
The question (practical enquiry) was , “Which liquid would evaporate the quickest?”
To do this they would compare (comparitive) different liquids. Robins chose, plain water, salt water, oily water, orange squash and chocolate mix!
To ensure it was a fair test the ensured each liquid was the same amount and placed in the same area of the classroom.
Today, they observed,
Which liquid has evaporated fastest?
– Has anything else happened to any of the liquids?
– Is there any separation?
– Have any gone mouldy?
– Or smell funny?

Look what happened over the weekend!
Extension: Read more about condensation and evaporation below.
Condensation and evaporation are two separate changes of state. Evaporation is when a liquid is changed into a gas. The particles in a liquid are moving and only few have the right amount of energy to escape and become a gas. This process is important because we require it for our earth’s water cycle. It can happen on all surfaces at any time.
Condensation is the process in which water vapour (in the air) is turned into liquid water. You can kind of think of it as the opposite of evaporation.

P.S Look at cheeky Mr Lo giving Robins an impossible word search to do for the morning activity on April 1st!
