A Bit Of A Mix

In science, we were presented with a large mixture that needed to be separated as efficiently as possible. We first discussed different ways common materials are separated such as using magnets and sieves.
In our challenge, we had to think about these and then separate the mixture using paper plates, foil and magnets but sieves were not allowed.

The mixture included

• Coffee
• sand
• paperclips
• sugar
• salt
• rice
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  

Many groups decided to try making equipment that resembled a sieve. There were fantastic conversations about ideas. They did this by piercing holes in the paper plate
The lesson ended with the question 'How can we separate sugar, salt and water?'
