Hurricanes - A hurricane is a large storm with heavy winds and rain that begins in the ocean and builds up strength as it moves across the water. While some of the damage caused by hurricanes is from high winds, most of it is usually from tidal surge, flooding entire cities, and killing large numbers of people. A tornado is a storm that develops on land, with no warning, and moves in a circular motion with heavy winds with a funnel shape, picking up and carrying dirt, dust, and even objects. The damage caused by tornadoes is from the high velocity winds, which are extremely destructive and deadly. They can demolish entire neighborhoods in a matter of a few seconds to a few minutes.  Tornadoes can form when hurricanes make landfall, as their winds at ground level slow down, while the winds near the top keep their momentum, but a hurricane cannot be created by a tornado.

Tropical Depressions - Hurricane Katrina began as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005. The depression later strengthened into a tropical storm on the morning of August 24 where the storm was also named Katrina. Katrina continued to move into Florida, and became a Category 1 hurricane only two hours before it made landfall around Hallandale Beach on the morning of August 25. The storm weakened over land, but became a hurricane again while entering the Gulf of Mexico.

Fires - Fire needs three things to burn: oxygen, fuel, and heat. Fuels can be wood, tinder, coal, or any other substance that will easily oxidize. Therefore, a fire can be stopped in three different ways, by removing any of the three things it needs to burn.   The fuel can be removed. If a fire burns through all of its fuel and extra nearby fuel is removed, the fire will stop burning. The oxygen can be removed. This is called "smothering" a fire. Fires cannot burn in a vacuum or if they are covered in carbon dioxide.   The heat can be removed. The most common way to remove heat is to use water to absorb that heat, putting the fire out.

Flooding - When a river receives a lot of extra water it may flood.  During a flood there is plenty of water, and most people wouldn't think that dehydration was a serious risk, but flood waters are mostly polluted and not safe to drink.  People who drink the contaminated water may suffer from illnesses or diseases such as typhoid.  You can prepare for flooding by filling many containers with fresh clean drinking water.  You can also use sandbags to protect your house and to soak up the water.  Be prepared and be safe.

The cardinal and the cedar waxwing are two common birds. Both have crests on their heads. Both are common at bird feeders. But the birds have some differences.

This morning was crazy. My alarm clock was set for PM instead of AM, so I woke up really late. I just threw on some clothes and ran out the door. I rode my bike as fast as I could and thought that I was going to be late for sure, but when I got there everyone was outside and there were firetrucks all lined up in front of school. I guess somebody pulled the fire alarm before class started. It worked out though, because nobody really noticed or minded that I was tardy.

The dodo bird used to roam in large flocks across America.  Interestingly, the dodo wasn’t startled by gun shot.  Because of this, frontiersmen would kill entire flocks in one sitting.  Unable to sustain these attacks, the dodo was hunted to extinction.
