This problem and project-based lab activity is a culminating project that follows my previous two activities exploring density and buoyancy.
1. Density Exploration (and accompanying slideshow)
2. Cartesian Divers (and accompanying slideshow)
This project can be used alone or in combination with the two previous activities for a more in-depth study of these scientific principles.
During this activity students will use the engineering design process to design the most efficient raft possible to enable them to get off the island.
and problem enables students to explore the concept of buoyancy by constructing and experimenting with Cartesian Divers. This lab uses simple materials including straws, clay, binder clips, and 1 or 2-liter bottles.
This activity may be paired with my simple slideshow on Cartesian Divers, which can be accessed via Powerpoint or Google Slides.
This activity can be used independently or as a part of a Watercraft unit. This activity is preceded by a laboratory experiment exploring density. This activity can be followed by an engaging hands-on, problem and project based activity in which students construct a raft to "get off the island"
