Read the passage in Part 1.
Technology can be good or bad. That’s why learning to be safe online is so important!
Personal information
Most of us have our names and photos on social media. But without the right privacy settings, they can be used by dangerous people. Everything you post or send online could be taken and used against your will. And once it's online, it's nearly impossible to get rid of it completely!
Also be careful of what others send you. If you click a link or open an attachment, it can be something dangerous for your computer, like a virus.

Cyberbullying
You probably know that cyberbullying is bullying, but online. Sending hurtful messages, spreading lies about someone, sharing their private photos… these are easy to do, but they have a huge impact on the victim. The best way to deal with cyberbullying is to ignore, block, and delete. Telling a trusted adult is also important, especially if someone is threatening you.
Be careful with your information. Think critically about everything you see online. Be kind to others. These important lessons will help you and others stay safe with today’s technology.
