Year 4 carried out a series of 'wacky races' to find which liquid would travel to the bottom of the slope in the shortest time. Whilst ketchup never really got moving, the lemonade moved like lightning! The children talked about how they could make the test 'fair' by keeping all the variables the same apart from the liquid. 

Then, we moved on to find out about solids, liquids and gases. The children were surprised to discovered that some of the balloons contained blocks of ice, whilst other balloons had been filled with water. 

 

Using marbles in a container we investigated the structure of the molecules in solids, liquids and gases too.
