Free printable snowflake patterns for winter science lesson plans

 Good morning! Teacher Omi (grandma) on this lovely winter day! We were just hit with a massive blizzard and it reminded me that when I homeschooled our kids, the weather and seasons played a big part in our lesson plans. Here are free printable snowflake patterns to extend winter science lesson plans! 

First Palette has long been a favorite for free printables, activities and lesson plans. This site offers free printable snowflake patterns and templates for snowflakes to cut. Use these to explore crystals, three forms of matter (solid, liquid, gas), fraction math and weather lesson plans. 

When I was a kid, we learned to cut snowflakes by folding paper. A snowflake crystal always has six sides. To create that, you need a perfect square piece of paper. And to create that from 8x11 paper, fold in half and then half again (quarters). Then without creasing, fold again, into 8ths and cut the excess off. Now open the paper and fold diagonally to form a triangle and then in half again so the points of the triangle meet. Now fold both sides half way in, so they overlap and cut off the excess. 

What you are left with is 12 sections, folded in on each others. Keeping that folded, make any cuts you like but don't cut all the way through. You can cut the center point to make an open pattern. Whatever cuts you make will be repeated 6 times. The snowflake pattern is achieved when the 12 sections are divided into six repeated sets of two each. 

You can do the same design folding the paper into 8ths. You'll still have 12 sections only this time, the pattern will be repeated four times instead of three (or six). It won't be a  snowflake but it will be very pretty. And you can teach fraction math and also the factors of 12: 1, 2,3,4, 6 and 12. You can also teach symmetry (mirror images) by showing how, when you open the snowflake pattern, the repeated patterns are facing each other, exactly the same but opposite.
