This will be a long post about weather changes that we call fronts! I'll divide it into sections to make it easier to choose parts to read.

This site below has a better explanation of warm and cold fronts than your book.
However:
1. It has some ads. You shouldn't click on those, because they are off-topic.
2. The song at the top won't teach you as much as reading the text.
3. Click on the arrows at the bottom (near the middle) to get to the next page.
4. When you get to the page on tornadoes, that should tell you that you're in a different chapter. The changeover is abrupt!

This site will show a scientific demonstration that PROVES warm air rises above cold air (just like warm water rises above cold water). There is a video ad that plays before the demonstration that you have to watch (or mute the sound).

This video below is a cartoon, and the characters give a good explanation of fronts, but they make a few little mistakes:
1. They say "it creates some weather," but they mean, "it creates some precipitation.
2. Don't throw a snowball at someone's head, even if you are demonstrating science.
Also, they tell you the names of each different warm and cold front in the United States, which is interesting, but won't be on your fourth grade test. :)

Finally, here is a song that might sound familiar to you. Most of it is very complicated, but the bridge (repeating part, shown left) does tell you about warm and cold fronts! Listen to the video below.
