EPISODE 16 - Why is Matawhero Red?

Learn why Matawhero is red.

MATERIALS:

  • About 1 cup of light-colored sand  
  • 1-2 plain steel wool pads
  • Plastic container or small tray
  • A jug of water
     

INSTRUCTIONS:

  • Start by placing the sand into the plastic container – this sand represents the soil on Mars. 
  • Next, put the steel wool in the container and mix the sand and steel wool together.
  • Then pour a little water into the container. The sand and steel wool should be very damp, but there shouldn’t be a layer of water in the container.
  • Leave it aside for a few days, adding water everyday so that the sand doesn’t dry out. 
  • Observe what happens and write down what you see. 
  • After three days, you’ll see the sand will change colour. This happens because the steel wool contains iron and when mixed with water and air the iron starts to rust. The rust mixes with the sand to turn the whole mixture a rusty red colour – just like the soil on Mars.
