This STEM resource is classroom ready and is part of my STEM 5 Set product. Included is one engineering design challenge, challenge rules, student pages and handouts, materials list, student lab sheet and reflective questions. This product has been used in the classroom. It is a very engaging engineering lesson and easy to set up and use. Your students will enjoy this lesson while working with the engineering design process.Be sure to have your students graph their work (individual and group). Students will be measuring weight (grams).
