In this week of science we talked about fires. The three things needed for a wid fire to start a source of heat, fuel such as dead trees and oxygen. When trying to make a fire last longer you will want to shave a flat side off of 2 logs. Then make it a little rough by putting some chops in it. Collect as many wood chips as you can that may have flown off. Put the biggest log on the bottom with the flat side up. Then place the wood chips, and some bigger sticks on top. Then place the other log on top with the flat side pointed down. Use some big branches to hold it in place. Then light it.
