On the 100th day of school, 5th grade students in Miss Mehring's STEM class worked in teams to create a sustainable standing tower using marshmallows and spaghetti. Students were only allowed to use 100 pieces total, so they had to select their mini marshmallows and pasta strands carefully! Through trial-and-error and teamwork, the fifth graders brainstormed how to create a strong foundation and how to work their way up without the tower collapsing.
