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. Good luck you wont be disappointed.The Blue Planet is a documentary series released in 2001 by the BBC. I just waited and bid, set your limit, and you will get one soon enough. I didn't have to pay an arm and a leg for my copy. If not there are always some that do start at. All of the BBC Planet Series are a great tool for teaching and every school, library, and PBS should show it more often so that maybe then more and more people will learn to protect our Earth before anther species is gone! Even if it is a fish is still is an a living creature GONE forever.Īs for the price, watch eBay you'll find one cheap enough! Almost everyone who sells DVD's always has a sales. They are a very good resource to help teach our children that we need to respect and protect every living thing on this Earth, even if we don't think it matters because it does. I love to just sit down on a saturday, put in one of the DVD's kick back, relax, and just dream. I would recommend this set as well as all of the BBC Planet Series to any family for video night, the DVD's are much better than just watching a plain old movie (although we do like those to) these series are just awe inspiring and a great addition to any home movie collection! I can't say there is anything bad about them. It show us living things we have never imagined. It gives a chance to dream together of place or things we would like to see or do together or "someday". My family and I love the wonders of the worlds. If you like to see the wonder of the ocean Here it is!
