Things got messy!
A spaceship landed on our school field and contaminated all of the water, and we were given the challenge of trying to clean it again!
We were provided with a variety of equipment, including sieves, filter paper and magnets, rulers, toilet roll and a paintbrush in order to separate the materials. We had to be careful though, as some of these items were red herrings and would not help us to complete the mission! Take a look at our experiment – making the water clean again was harder than it looks!
