Right now pollution is in our oceans, which is not good if we don’t stop now our oceans will be a waste bin for plastic. So here are 5 things the plastic is doing to our oceans. 1. is making our beaches look like trash The beach is a nice place family and friends can go to. Unforceitly the plastic washes up on the sand making it not as nice as we would wish. 2. marine animals dying These poor creatures are being killed because of pollution. The reason they are dying is because they ever eat the plastic or get stuck in it which is the reason they die. 3. marine wildlife home being taken over by plastic Would you like your home to be covered in old plastic?

On a clear night, the dusty ring of the Milky Way can be seen in the night sky. The Milky Way was made of over galaxies  In order for the Milky Way to achieve its current size and shape it has consumed other galaxies throughout its history.

Day 13 | A day off

Hello, Today we had a day off from home-school. This was because our Mum was having a bad day health wise and needed to be able to rest, and Daddy was really busy. THEO: I have played on the computer ALL DAY!!! It was really cool as I have a sword to level up in Minecraft and so it was nice to be able to just do that. ELLA:  I decided to do some colouring, and have spent some time reading my book. Finishing the book was the monthly goal I set myself, so I'm trying to read a chapter a day.
