Raining, windy, housebound. It inspired some weather based experimentation. So we busted out one of our science kits, that had a few rather cool stuff to do and make.
The first thing we made was a wind directional thing. A weather vane? I do not know if it has a more proper term...
So we used straws and cut up an index cards to make the main part.
We made the base by sticking a nail in the eraser of a pencil, and making a base out of play dough, so it would stand unassisted. Then we perched the straw on the nail. We brought it outside, but of course the wind had stopped.
So we brought it back in and blew like crazy at it. The kids would giggle every time it pointed to the one who blew at it. They tried hard to trick it, but they always got caught.
Next, we made a thermometer of sorts. We took a bottle and filled it with colored water.
Well, what happened was that the heat from the bowl of water made the water in the straw raise above the water level of the bottle. So like a thermometer, heat made it rise. So of course we had to immerse it into icy cold water to watch it reverse.
And it did. And that led to 45 minutes worth of thermometer play.
I think you get it. Next we decided to make a barometer.
We took a balloon, cut the neck off, and stretched it over a jar. Then we taped a straw in the middle and put paper behind with a few marks. Depending on the air pressure, the straw will tip up or down, giving a clue on if rain or sun is in store.
But no one seemed done yet, so I took out a compass and we tried to figure out directions,
and we spilled water on the table and used a straw to be a wind blowing in different directions,
AND we built a rain catcher to see how much rain we could collect in a six hour window.
But then of course, the rain stopped. So we did what anyone would do. We made cookies!
