Ms. Lehman's Kindergartners recently engaged in a STEM challenge. The students were given a cup of candy corn marshmallows and a cup of toothpicks. The students worked with partners to build the tallest free standing structure. The students had 15 minutes to work on their structures. After the 15 minutes, the class came together to discuss frustrations and what they could do differently with their structures. The biggest student frustration occurred when the structures would fall apart. The class discussed how to make the structures more solid and they came up with the idea to form a square as the base. Another student added extra toothpicks to the base to support his tower. The class then had another 15 minutes to redesign their structures. Some students redesigned their structures three or four times! At the end, the class walked around the room playing "museum" where the students took a look at all the different structures the groups created.
