Focus: To consolidate pupils' learning about the ocean floor in a creative and fun way. Through creating diorama, pupils will think what looks like species live there. Learning objectives: In this activity, design, classify, find place for all elements characters that compose biodiversity they have learnt class.

[1] Rough topography on the ocean floor is a source of ocean mixing which is of interest to both physical oceanography and climate science. Most mixing has been attributed to high slopes of the large-scale structures of the deep ocean floor such as seamounts, continental margins, and mid-ocean ridge axes. In this paper, we show the small-scale but ubiquitous abyssal hills and fracture zones dom...

closed system grossly distorted sound calibration below 1 khz, whereas at frequencies higher than 6 khz calibration for the open loudspeaker was affected. This difficulty could be avoided by placing the loudspeaker close to the bird's ear (12 cm). 2. R. L. Boord and G. L. Rasmussen, J. Comp. Neurol. 120, 463 (1963). 3. For this reason, all data on single-unit thresholds and frequency range in t...
