we used waste material

Our Year 3 group took part in the "Whats under your feet" campaign in the final week of school before half term. They had a great time investigating and seeing what they could find. We used 2 plots of 30cm x 30cm, one of which was under a tree and one which wasn't. Our results were very similar in numbers but the size difference of the worms were very different. Patch 1 found 29 worms, 3 centipedes, 1 earwig and 3 grubs. The worms from this patch had high numbers in the 2-4cm bracket and the 4-6cm bracket. The longest worm we found in this patch was a whopping 14cm! Patch 2 found 24 worms, 1 centipede, 1 earwig and 3 maggots. The worms from this patch were much smaller in size with the overwhelming majority in the 0-2cm bracket. The longest worm from this patch was 12cm in length. The children enjoyed the experiment so much that they are now counting down to the next dig already!

We used the grass area outside the classroom to dig a square patch of grass and earth following the instructions on the video by Dr Martay. It had rained a lot during the week which might explain why we found so many worms - 12 in total. Looking closer we also found two baby spiders crawling around in the tray and one black slug.The boys quite liked holding the worms and slug.
