We have been working on our new science unit meteorology and weather. First I wanted the children to better understand the layers of the atmosphere. So we created a poster that identify the different layers and what can be found in each layer.
|Kids identified the different layers of the atmosphere|
|I found some clip art that we used to identify what things could be found in the different layers of the atmosphere|
|Then we discussed the gases found in the atmosphere and how it dissipates the higher up in the atmosphere|
|We looked at how air expands as it raises--we did this by gently blowing bubbles into a glass of oil, the bubbles start small and then as the bubbles rises to the top it becomes bigger until it burst. (It was very hard to get a picture of that)|
|We set it outside and watched the water raise with the cold air! Then we brought the bottle back inside and watch the water reside back into the lower bottle.|
|The next barometer we made was similar above but this time a partially blown up ballon was placed inside a jar and the ballon was taped over the edge of the jar.|
|This was not nearly as successful as the others but it still worked|
|The last activity we tried was taking a water bottle and filling it with about 1/4 cups of boiling water, replacing the lid and then setting it in a bowl of water. Within seconds the kids saw the bottle clasping.|
|The next morning we woke up to snow and decided to do the same experiment but use the cold air and see if the results were the same. As you can see here the results were even better:)|
Another experiment we did simply because we had unexpected snowfall in March was measuring snow and noting how much water it produces once it all melts.
|We filled up a Measuring cup this one is just over 1 and half cups|
|Then watched the snow melt|
|And the kids were surprised to see that the snow only produced about 1/4 cup of water!|
We had fun learning about the layers of the atmosphere and air pressure and we are now moving on the learning about clouds:)
