Students could even create models of their ideas and simulate the floating from seafloor to sea level in a large fish tank filled with water. This electronic board will allow students to debate this topic with students around the country and people around the world. At this point give students the assignment below. Deep-sea ocean research has many parallels to space research. The ocean floor and outer space still hold many mysteries for scientists, and both involve expensive research equipment.
Submersibles allow scientists to dive to the ocean floor but are much more costly than ROVs.
ROVs can stay underwater longer than submersibles. Create a list of the pros and cons for both human and robotic scientific exploration. Consider limited resources such as grant money. This electronic board will allow students to debate this topic with students around the country and people around the world. Much like the claw in an arcade game, the mechanical arm helps collect a black smoker for further scientific study.
