This winter, in my neck of the woods, has been really odd this year. Usually we are up to our eyeballs in snow, but this year we've only had a couple of minor snowfalls. A few days ago it even got up to 55 degrees and we were able to take a bike ride to the park! In my
lesson plan for this week I had down that I wanted to do a science activity about measuring how much water is in snow, and since there was still a little snow on the ground on Monday, we did it right then before it could melt!
Trevor is always super excited to do science activities, and this one was no different =)
First we scooped snow off of our balcony into a large pyrex bowl. Here's Trevor trying not to get his toes cold!
Oh boy, I think this is going to take a while!
After we all took turns scooping, we got the bowl filled up!
Next we measured how much snow we collected (it was about 6c. even thought this picture makes it look like more...) Then we reviewed what snow is made of and how we could make the snow turn back into water. I figured that we could just leave the snow sit for a while, but Trevor mentioned using the microwave, so that's what we did! It was a nice option because he was able to watch it melt from snow to water right before his eyes!
Here is what we were left with! I asked Trevor to look and wee how much water we got and this is what he did...Oh, little boys =)
The 6c. of snow yielded about 1c. of water. To make sure that I got the story right, I found a website that did the same experiment and they had a great explanation of why snow takes up more room than water. From
HomeTrainingTools ...
Snow is made when water freezes in the form of ice crystals that we call snowflakes. The
pointed star-like shape of a snowflake causes its points to stick out far from its body,
allowing the snowflake to take up a lot of room. (If you stick your arms straight out from your body,
something similar would happen with you! Your arms cause your body to take up
more space and you may find yourself bumping into walls or having a hard
time making your way down a hallway with your arms sticking straight out.) When
lots of snowflakes pile up, their points keep them from getting very
close together, creating empty space in between the
snowflakes. When the snow melts into water, the snowflakes no longer have their
points, and the space between them disappears. (If you put your arms down next
to your body, you are no longer taking up so much space and can get much closer
to other people and things.) So the melted snow takes up less space as water
than it did as snowflakes.
What a great explanation! To help them understand, I had Trevor and Mackenzie pretend to be snowflakes and stand with their arms out and I asked them to stand as close as they could. They saw that they could only get so close before their arms ran into each other. Then they 'melted' into water by putting their arms down, and now they could stand right next to each other, taking up far less room! I'm sure they didn't really get the correlation between this and the snow, but it was fun to do =)
