The National Science Foundation developed the TeachEngineering.org project, which has resources and activities that teachers can use in their classrooms and curriculums. I scanned through many of these activities and prepared a critical review of one called Charlotte's Web. In this review, I discussed the materials, benefits, and practicality of this activity and how it might be used in the classroom. Below, I have attached my critical review, which contains pictures of the activity as well.
