In this lesson, students will learn about the history of hovercrafts and how they work from a PowerPoint presentation that has been converted to a PDF. This is a great lesson to incorporate discussions on Potential and Kinetic energy. Students will go through the engineering design process to build and test models of hovercrafts using the supplies provided by the teacher. They should make a couple of models to be able to observe and discuss what they are noticing. This is a great Montessori lesson. It is open-ended and inquiry-based. This lesson gives students a lot of choice in materials and they can work collaboratively, or as individuals. A lab sheet is provided that walks students through the EDP. Materials for this activity are inexpensive - can even use recycled materials. Great activity for anytime of the year. I used it as an end of the year activity.
