Our trip to the beach

When Room 2 went to the beach to learn about sand dunes, I learned that sand dunes are formed by wind eroding the mountains and breaks the rocks to make the sand, and the sand goes into the river. The river takes the sand into the ocean, and the waves deposit it on the shore, then the wind blows it into the sand dunes. 

Wind can put more sand and take the sand away. Storm waves can erode the sand, and humans can damage the sand dunes by running on them. We can protect the sand dunes by planting plants, like the... I can´t spell them! Bugs also live in these plants. A type of spider, lizards and geckos, they all protect the sand dunes. The plants hold the sand in place so it doesn´t blow away. 

Did you know there used to be a house near the sand dunes? The people who lived in it couldn´t see the sea; the sand dune was in the way, so they decided they would get part of the sand dune scooped away. Seems good enough, huh? No. The wind funnelled the sand inwards, and into the house´s roof space. A few years later, the roof collapsed with the weight of the sand. Don´t mess with nature!

 

Here´s a picture. We had to build our own sand dune and show how we could protect it!
