This digital weather station looks like so much fun. Kids set up the station and use tools that measure temperature, humidity and other weather indicators to put together their own forecast. The can also measure air pollution, rain pH and build a barometer. It also comes with an activity book. You can get it for $39.98.
The DK Eyewitness Weather book has amazing weather pictures as well as facts about weather and climate. This is for middle age kids, but even younger kids would enjoy the pictures. I love the DK Eyewitness books, our whole family enjoys reading them together. You could also get the Eyewitness Weather DVD.
Here's a great website that kids can use now and all year long and it's free. It's called Weather Wiz Kids and it is such a fun website designed by television meteorogist Crystal Wicker. You can find lots of information on tornadoes, hurricanes, clouds, weather experiments and games, coloring pages, even weather jokes like this one:
Whatever happened to the cow that was lifted into the air by the tornado?
I can remember when my daughter was afraid of thunderstorms when she was a preschooler. It really helped her to learn about what happens during a storm and that the loud thunder could not hurt her. She enjoys learning about weather; our Science Museum has a great Weather Discovery area for kids and she loves doing the cool experiments they have.
Are your kids fascinated by weather, terrified by it, or could they care less about the weather? :)
