With valuable data on the ocean floor, a submersible would need to venture to the bottom of the ocean. It would then need to return to the surface of the water so that the ocean engineer could retrieve the information. Knowing about density is important in making sure the data is able to be collected! Therefore, a submersible needs to both sink AND float!
Testing various instruments, second graders are discovering that density is a key factor in getting something to sink and float. Every time they added a new instrument to their submersible it changed the overall mass and volume, and therefore, density.
