In this STEM challenge, students will save Christmas by redesigning a new mode of transportation to replace Santa's broken sleigh. Materials can be as simple or as extensive as you want. I will be using things I already have in my classroom....popsicle sticks, yarn, string, coffee filters, paper, cotton balls, etc...This is an amazing activity to get kids engaged in STEM! Can be done in 2 class periods. This can also be modified for any grade level!!
