Bridge STEM Challenge

 The 5th graders had to build a successful bridge that was at least 14 cm long. We first watched a short video on what makes a bridge strong. Then they drew a sketch of their bridge with their group. All groups were given the same amount of cups, toothpicks and marshmallows. They had 25 minutes to complete their bridges. The longest bridge that was made was 20 centimeters! Some groups were successful and some were not, but they learned what they could have done to get better support.
