There are three things to remember:
- Make it funky!
- Make it short - about 200 words
- Send us photos if you can
Remember, this isn't homework, so write something you think your best mate would want to read.
If you do send photos, a parent or guardian needs to sign the back of them to show they're happy that we might publish them on the web.
If you email them, make sure a phone number is included so we can check your parent/guardian is happy for us to use them.
So get writing!
Email your report to:
Or send it to:
CBBC Newsround Online
BBC White City
London W12 7TS
If there's anything you're not sure about, you can also email us at the same address to ask us a question.
Good luck - and we look forward to reading your report soon.
