Have an Octoberfest and try German food. You have the children dance, drink sparkling grape juice and even organize a parade with the children. Fire Fighters Talk about fire safety, and have a fire drill. Show the children the fire extinguisher, then go outside and show them a fire hydrant and how it works. Most fire stations will give preschoolers a tour for free.
Police Officers Make about traffic signals out of red, green and yellow paper.
Talk about what each color means. Talk about the importance of never talking to strangers and what to do if a stranger makes you feel uncomfortable. Talk about the emergency police number and when to use it. Explain to the children to go to a police officer if lost or frightened. Have the children memorize their address and phone number so they can tell a police officer if lost.
