Algae in the changing Arctic ecosystem

Algae in the changing Arctic ecosystem | IB Biology | Scoop.it
Laura Nielsen for Frontier Scientists

The Arctic hosts a complex ecosystem, sensitive to the alterations in our changing world. Algae is part of that biome, growing in strands which hang down from the edge of ice floes.
jlinzel's insight:

An interesting article on Arctic sea ice and algea growth. Hard to predict the connections of life.

The educational opportunities in addressing misinformation in the classroom

The educational opportunities in addressing misinformation in the classroom | IB Biology | Scoop.it
An interesting discussion arose in Tom Farmer’s latest blog post about our textbook Climate Change Science: A Modern Synthesis. One of the commenters questioned whether certain sections should have been included in the textbook.
jlinzel's insight:

I ran into this the other day and HALF side stepped it. I think I need to use it as a teachable moment. It occurred when an IB bio student of mine stated that another teacher they have 'doesn't believe in climate change' - students choice of words. I attempted to probe but maybe too cautiously. I think I need to address if any evidence or basis of concept was presented to defend the position.

Seven TED 2013 videos you don’t want to miss | eSchool News | IB Biology | Scoop.it
These days, it seems even the masses—the Silicon Valley masses, specifically—have an education-focused mindset, and to prove that point, this year’s TED Talks focused on education in particular.
jlinzel's insight:

So, these are gret stories about exceptional kids. What do you think, do ALL kids have the potenital to do this? Obviously not every student will achieve THIS level of success but can they all self-direct, with guidance if they find a subject they WANT to pursue? Is it ONLY a matter of finding the topic? What do you think of a 'saltatory' curriculum? [I think I'm the first to think of this idea in this context] Can students achieve high level of understanding by 'jumping' over 'unnecessary' content? Lets face it, 'mastery' in many areas now requires a PhD. I've had this idea that jumping through important conceptual topics while bypassing potentially unnecessary content could allow students to identify and pursue thier area of inspiration more quickly. Is this a CRAZY idea? Does the 16 year old have the total content of a PhD? Probably not, he ad to have jumped a bunch of content/ideas/etc...is this acceptable? Are the gaps ok?

Carbon in permafrost and tomorrow’s atmosphere

Carbon in permafrost and tomorrow’s atmosphere | IB Biology | Scoop.it
Laura Nielsen for Frontier Scientists

Carbon is the building block of life.

Our knowledge of current climate change, however, has us counting how much carbon enters the atmosphere.
jlinzel's insight:

Another great climate change article. I'm gathering enough that I think a one class symposium might be in order. Each student picks one of these stories and presents a 5 minute explanation meetings the IB guidelines on climate change. Assessment - then done. Maybe with a follow-up paper 2 question.

I'm not familiar with 'McClathcy newspapers'. Anyone? But this does seem contradictory to a report developed by a Canadian grop of insurers. I know I have the report somehwere that the Canadian group is accounting for cliamte change. Question is, is it enough?

jlinzel's insight:

I didn't teach this BUT epistasis is an intersting topic and this post relates to something I'd like to touch on with my IBs in the genetic unit. If they can get a small liver of genetic control of develpopment then it links VERY well with diversity of organisms. High school biology contains so much on DNA structure, protein structure, etc....why do we do this without the context of the EFFECT of this. You are a developmental pattern of cellular and tissue organization. The genetic variation we discuss in biology results in developmental differences between AND within species. So what if students know A,C,G,T without the context. Even the inheritence, I am relaly starting to think that emryonic development is the crucial cenrtal link. What do you think?

jlinzel's insight:

When I was 5 years old my parents took our entire family on a road trip from Fenwick Ontario to Fairbanks Alaska. We took the not yet finished Alaskan Highway through Dawson City. Somewhere, I don't know where exactly, I remember watching some type of team using high pressure hoses to wash away a glacier. They were extracting a skull just like this. I need to go home and find that picture from the summer of 1976. Thanks Mom and Dad for that trip.
