This week, Year 3 learnt all about what soil is made up of and how its formed. The children learnt all about how worms help to increase the amount of air and water that gets into the soil. We learnt that they break down organic matter, like leaves and grass into things that plants can use. When they eat, they leave behind castings that are a very valuable type of fertilizer. We then created our very own compost bin complete with worms! The children used the bottom of a plastic bottle, compost, water, vegetable scraps, stones, water and worms to create their compost bin with their table. As worms like the dark, we covered the bottle with cardboard and put a breathable fabric over the top of the compost bin. We will check to see how our compost bins are doing every couple of days. The children loved getting their hands dirty!
