4th Grade STEM – Bridges


IMG_0886

Recently students in fourth grade were studying geometry in math and extended the lesson to science as well and employed science, technology, engineering and math into their studies thereby making it a complete STEM lesson. During their geometry unit, they discussed why bridges are built the way they are and spent time identifying geometric shapes found in bridges.  The students had to build horizontal ladders (bridges) and predict how many dominoes long they could build their bridges before they fell. They also had to decide the best method of construction and measure the final length of their bridges.  The kids had a blast!
