Project weather school is a new initiative to introduce different types of weather, and weather-related topics, in a fun way to students.
The first topic is areas of high and low pressure. Areas of pressure are what are in control of weather around the entire world. It seems complicated at first but once you dive deeper in, it’s an easy way to understand how air moves all around you.
High pressure is typically associated with cool and dry air. On days where a high pressure is present, skies are typically very clear. These are the days in the winter where sun shines high in the sky. Low pressure can typically be linked with warm and wet weather. When storms roll into an area, low pressure is to blame. Areas of both high and low pressure are possible in all seasons and temperatures.
A mason jar, a balloon, water, a match, and a piece of paper are all you need to help teach your children about these areas of pressure.
To start, fill up a balloon with water. You only need to fill the balloon big enough so that it is unable to fit inside the mason jar. It should sit on top easily. To add a bit of extra fun, you can allow your children to color or draw designs on their balloons.
Next, take a small piece off paper and start it on fire. You can do so using a match or a lighter. The source of fire will not affect the experiment at all. Next, pick up the balloon, put the lit piece of paper inside and set the balloon on top. The balloon will start to shake a little, and then it will get sucked into the mason jar partially. This happens because an area of low pressure is created in the jar.
After the outside of the mason jar cools down, allow your kids to pick up the mason jar by the balloon. A seal will keep the balloon stuck inside.
In order to reverse the experiment, or allow the ‘atmosphere’ to turn stable again, you can run the mason jar under cold water. Once the balloon is out, your children may enjoy throwing it outside or playing a fun game of catch with it.
