STEAM Challenge: LEGO Sun Prints
This week, we challenge you to make a LEGO sun print! All you need are LEGOs, construction paper, and the sun. Take LEGOs and place them on a piece of construction paper. I used purple construction paper, but you can try a different color. Place the paper out in the sun. I taped the paper to a tray and placed it in the sun since it was a windy day. I left the LEGO print outside for 3 hours.
As you can see, the sun caused the purple construction paper to fade to a gray color. You can see the outlines of where the LEGOs were placed on the paper.
The sun is made up of ultraviolet rays. These ultraviolet rays can break down the chemical bonds in different materials changing their color.
You can try variations on the activity by using different types and colors of paper or change the amount of time you leave the paper in the sun.
Post a picture of your sun print on Facebook or Instagram. Don’t forget to tag @librarymahoningcounty #PLYMCSTEAM
We can’t wait to see what you make!
