I would use this activity to help students get an idea of where they actually are in regards to the bigger idea that they live in a house, on a street, in a city, in a state, in a country and so on. This is helpful for students to actually get it so that it makes sense on their level. You could also do this on a smaller scale first of the school so they get an idea before the large scale project that this is.
"It doesn’t matter where you live, you are susceptible to an earthquake, hurricane, snow storm, power outage, flood, etc. and any of these things could leave you and your family stranded at home for a few days without power or electricity." Emergency kit item lists for your car, pet, home and family. Good info.
A great idea for teaching kids about the important place they play in their community. This helps to build a sense of identity and purpose. I would tweak it a little though so it doesn't look like they are the center of the universe
