We heated one mug of water and did not heat the other. Then we put a clear plastic cup on top of each one. The water that we heated turned into STEAM and we could see it in the cup!! That’s EVAPORATION!!

The water drops in the clouds are just a little bit heavy and the air is cold so there is a tiny bit of precipitation falling from the sky in the form of … SNOW!!! Not enough to capture on the video camera, not enough to play in, not enough to make a snowman (or even a snowball) but snow all the same!
We are starting to learn about water and the water cycle and this week we are focusing on precipitation. Did you know that precipitation is what happens when the drops of water in a cloud get too heavy?
We conducted an experiment using a sponge as a model of a cloud to see if we could make precipitation (rain). The cup with just a little water didn’t fill up the cloud, it wasn’t heavy enough to make precipitation so the water just soaked into the cloud. When we poured a LOT of water into a different cloud, it became too heavy and wouldn’t soak into the cloud anymore so some of it fell out! That’s what happens in the sky to make rain!!
On Wednesday morning, the weather cooperated with Mrs. Mays’s lesson plans and we got to see precipitation!
On Wednesday we learned that when the air is WARM then the precipitation that falls is RAIN and when it is COLD then the precipitation that falls is SNOW.
Here are some pictures from rehearsal:
and from the Friday performances:
I have not transferred the video from Thursday night’s performance to my computer yet but will post the video of the entire program soon!! I think this year’s was the best yet!!
The last week of school before break, we made 33 dozen cookies to deliver around the school for Christmas!! First Mrs. Mays made a batch (3 dz) to demonstrate then each student got to make a batch.
Then on Friday (the last day before break) we delivered cookies to the office workers, cafeteria workers, custodians, speech therapists, bus drivers, and art/music/PE/library/computer lab teachers.
