New Unit!!

We are starting a new unit on migration. I knew a little bit about migration before. I knew that migrating is to move from one place to another. Today Mr. Schick told us that migration is a permanent movement which I did not know. I also know that some animals migrate like birds and butterflies. That confuses me though because migration is a permanent movement but we call birds and butterflies going South migration even though they return after winter. We also got a test, a quiz, and a worksheet back today. On the test I got a 97, on the quiz I got a 100, and on the worksheet I got an 80 which isn't too terrible. I'm pretty satisfied with my grade right now and I hope to keep it up.
