Safe Surfing Tips

It is OK to share some information on the Web– your username (SkaterGrl99, SnowboardJoe87)

(never give out your real name)– your favorite food, movie, band, hobbies, etc…

Information you should never give out– your real name– your home address– your phone number– your passwords

• (You and your parents are the only people that should know your password!)

Healthy computing posture

• Keep your back and neck straight.

• Keep your thighs horizontal with a 90° bend at the knees.

• Upper arm and forearm should form 90° bend at elbow.

• Sit back at least 2 feet from screen.

Good Computing Habits

• Active Breaks. – Get up from your seat and move around at least once an

hour. This helps your circulation and ensures that you do not stay in the same position for too long.

• Eye refocusing.– Look away from your screen every five minutes or so.

Let your eyes refocus on something far away.

• Blink Often.– Blinking lubricates your eyes.

• Clean Screen.
