Last Thursday Mrs Napier's class went on a trip to discover types of soil in our area. We split into half, 16 went to Portsdown Hill and the other half went too the shore. I went up the hill with Mr Wildman and Mrs Bryant and we looked for different types of soil. We also saw Old Man's Beard, which is a plant, and has a very thick stem and bits that float off if the wind blows. It only grows in chalk because if it grows anywhere else it will die because it doesn't like the soil.
When we were on the hill we dug and took some soil to compare it to the soil from the shore.
Back in the classroom we tested the soil types using barium sulphate and pH testing solution. We put the pH stick against the colour chart and chose which one it was closest to. It could be alkaline, neutral or acid. Red was acid, yellow is neutral and alkaline is green. The soil on the hill was neutral and chalky. Class 3N
