Hey 6th graders!
I know you will be able to find a lot of research about each of these natural hazards but if you need a few places to start....
6th grade teacher blog This is a 6th grade Social Studies teacher's blog. On the left side is a heading for Natural Hazards. Click on there. From there you should be able to click on the different hazard links. :)
A weather blog from a meteorologist : This site has a list of some natural hazards listed on the very bottom. Scroll WAY down :) Not all are listed, but there are a few.
FEMA site : This site has kid information sheets on many of the natural hazards.
National Geographic site This site lists many natural hazards.
These are just a few to start with. Not all hazards will be explained on these sites, but for some groups it is a place to start. Have fun! Learn a lot!
Search responsibly :)
