It was really interesting to see how the seas and the marine life adapted and were affected by the four seasons, handled in a way that was ceaselessly fascinating and left the viewer in awe visually. "Seasonal Seas", and the subsequent episodes, confirms my feeling that 'The Blue Planet' was consistently great and more and there was not a bad episode of the eight. To me, the series overall is wholly deserving of its acclaim and the individual episodes are rated far too low. As said in my reviews for the individual episodes of 'Frozen Planet', it is a shame that despite being one of IMDb's highest rated shows, the ratings here for each episode individually has such a wide divide between them and that for the show overall. It is also one of his most ground-breaking, in that it's the first comprehensive series of oceanic natural history and including and exploring creatures and their behaviour that had never been seen before. It leaves me in complete and utter awe every time, with how much is learnt about all the different seas and marine inhabitants and how it all looks visually. 'The Blue Planet' is one of my favourites of his. He has done so many treasures and even his lesser output of a long and consistently impressive career is still good. All animals are adapted for hunting or somehow gathering food from the sea itself.David Attenborough, as has been said many times, is wholly deserving of being called a national treasure, although it is a term he happens to not like. ![]() The dynamics of each of the ecosystems shown in this episode revolve around the nearby ocean. Teachable Moments: This is the only episode of the Blue Planet series that focuses on land-based life. Key Concepts: Coastal ecosystems, migration, breeding, seabirds, adaptations. ![]() The aquatic species will be adapted for surviving the threat of dessication during low tide. The land species will be adapted for taking advantage of the tide, gathering food quickly, and swimming. Animals, plants, and protists from both land and sea converge on this area. Teachable Moments: The movement of the tides produces very ecologically diverse ecosystems. Key Concepts: Tides, gravity, tidal bore, equinox, aquatic ecosystems, adaptations. Students will observe multiple types of interspecies relationships in this episode, ranging from competition to mutualism. Teachable Moments: Of all the oceanic ecosystems, the coral reefs boast the greatest biological diversity and complexity. ![]() Key Concepts: Coral reefs, aquatic ecosystems, coral polyps, biodiversity, food webs, symbiosis, interspecies relationships, parasitism, mutualism, commensalism, competition, predation. Water, having a high specific heat, does not have the wide range of temperatures that air does throughout the year, but it can still vary in ways that affect the biodiversity present. However, oceans within these latitudes also experiences changes. Teachable Moments: The concept of seasons is typically only associated with land ecosystems within temperate latitudes. Key Concepts: Seasons, latitude, aquatic ecosystems, migration, photosynthesis, plankton, food webs, food chains, keystone species. However, the biodiversity in the open ocean, away from the flow of nutrients from the coasts, is the lowest for all aquatic ecosystems.īlue Planet - Seasonal Seas View Worksheet Teachable Moments: The open ocean is often referred to as a "marine desert." This may seem contradictory to students, who perceive a desert as a hot, dry, sandy ecosystem. Key Concepts: Open ocean, aquatic ecosystems, euphotic zone, adaptations. This is a great opportunity to show how these factors drastically impact the biodiversity found within each oceanic zone. Temperatures drop, pressure increases, and sunlight fades away. Teachable Moments: The entire nature of the oceanic ecosystem changes as one travels deeper and deeper into the abyss. Key Concepts: Oceanic zones, euphotic zone, disphotic zone, aphotic zone, photosynthesis, chemosynthesis, adaptation, camouflage. Tip for teachers: Use closed captioning! Many of the animals and plants have very unusual names with very unusual spellings! Seeing them in text makes it much easier for the students to follow! ![]() I have not written anything for the first episode entitled "The Blue Planet", as it is largely a recap of the other episodes.Įach episode provides a tremendous opportunity for "teachable moments." Whether your focus is biology, earth science, or ecology, there is a good chance your concepts are covered by one more more of these episodes. The worksheets and student guides I have written for this series are all based on the BBC version starring David Attenborough as the narrator. There are a total of 8 episodes of Blue Planet. Each of the 50-minute episodes covers a different aspect of marine life. The Blue Planet is a documentary series released in 2001 by the BBC.
