STEM Project for Middle School—6th, 7th and 8th grades. In this S.T.E.M. lab, students will work in groups to build a bridge from index cards that will span some “raging waters” (blue construction paper). Their bridges will be tested by adding pennies until it falls! ***If you are interested in a differentiated version of this resource for grades K-8, please click here. This STEM Activity Challenge includes teacher instructions, student instructions (worksheet), grading rubrics, a demonstration video for the teacher, a materials needed sheet, and the related NGSS standards! In the teacher demonstration video, I give you an overview of the activity challenge, talk about the materials involved and where to get them, demonstrate how to set up the challenge for the students, and discuss the science involved. Teachers have found these videos to be very helpful by showing them step-by-step how to run the activity and giving them a better understanding of the science behind it. This activity will challenge students to work together in groups to complete the given task. These activities are fun, engaging, and the students will learn science in the process. Group work and problem-solving are at the heart of these STEM / STEAM challenges. Each activity challenge will end with a real-world research question, video, or activity. It is usually an extension of what the students just discovered and learned. The students will be involved, excited, and looking forward to future activity challenges in your classroom. You can customize the text in the Worksheets, Grading Rubrics, Materials Lists, and Teacher Instructions to suit your class! A link on the materials list page will take you to the Google Slides file.
