To kick off our new Science topic of Materials, we made Alien Soup. We received strict instructions from an alien personally on how to create the perfect Alien Soup.
However, once we’d finished following the instructions carefully, we found out we needed to get the salt back! We were quite confused by this at first and had lots of discussions about how we could get it back.
We used various equipment to separate the mixture, talking through the scientific process as we went.
In the end, we were left with salt and water. We soon worked out that if we boiled it, we could get the salt back, as you can see by the last picture – although some of us were very sceptical at first about this!
