Backyard science – winter addition

Posted 02-29-2012 at 11:54 AM by whitneywalters

I recently bought my three oldest kids a magnifying glass. Kairi just runs around the house playing with but  I have several ideas for different science projects I want to do with the older two kids and we did one of those projects recently.
We bundled up and went outside for some backyard winter science lessons. We took the magnifying glass to the snow and looked at the snow outside in our backyard. I talked about how all snow flakes are different and that it takes billions and billions of snow flakes to cover our yard in snow.

I explained to them that snow starts out as water vapor, ice crystals and dust. Ice crystals form when water vapor freezes on tiny pieces of dust and snow forms in very cold clouds that has very cold water droplets and ice crystals. The water droplets and crystals collide and stick together. When they fall they are what we call snowflakes.

Then we went over to the garage to look at the melting icicles and talked about why the snow and ice was melting that day. It was above freezing and  I made up a little rhyme to get them to remember what temperature would cause water to freeze, 32 degrees means that it will freeze.

Then we took the magnifying glass to the grass and the pear tree we have in the back yard. We talked about why the trees have no leafs in the winter and why the grass was brown and not green.

Of course we had to take some time after the lesson for some fun. So we made snow angels before heading back inside for hot chocolate with marshmallows.

    That sounds so fun! I can’t wait until my little guy is old enough to enjoy those kinds of things :)
