On Salmon Brains, Epistemology, and Internet Research Skills - 1 block in the life of a Grade Three Salmon/iPad Class
I love the last two days before a break. Our summative assessment is finished. Our UOI is complete. Our math test has been marked and corrected. Finally an opportunity to explore 'other things'. It's often the time when inquiry that feels most genuine happens, because it's the one time where there 'is' time.
Yesterday, we used our free time to dissect a salmon. http://mulgravesalmon.posterous.com/our-salmon-dissection
Today we had one block wide open. First, the students had a chance to review the pictures our student-cameraman Eli took to document the dissection. Then they had a chance to comment about something interesting they learned or about questions or curiosities they still had.
Many of the students were surprised at the small size of the salmon's brain. Khayali wondered, 'if the size of your brain doesn't always affect your smartness, then what does?'
This led a group of them to begin debating what it means to be smart. Jed suggested, 'well, what if you compare how much knowledge a salmon has to what a human knows.'
'Humans can't sniff their way back to a stream they were born in, and humans don't have their own sonar' 'Yeah, except salmon can't use iPads'. 'Okay. But before like two years ago humans couldn't use iPads and they still couldn't sniff their way up a stream.'
At this point it was still a casual chat, so we decided to explore 'salmon knowledge' and 'human knowledge'. Here were some of the things we brainstormed:
Things Salmons Need to Know
-what food to eat
-what stream they're born in
-how to avoid predators
-how to get to the ocean
Things Prehistoric Humans Needed to Know
-how to kill animals to make warm clothes and eat
-how to make fine to keep themselves warm and protected
-how to make weapons
Things Modern Humans Know
-how to write
-how to drive
-how to get a job and work
-etc.
We talked about instinct vs. knowledge. How do salmons and humans know what to eat? (Is choosing groceries at Whole Foods different from eating insects in a stream?), and we talked about how what salmon need to know hasn't changed much over thousands of years; however, what humans need to know has changed rapidly. Sahra thought it was because we 'have gotten smarter and evolved and adapted to new things', others suggested 'technology has changed us and our environment has changed and has changed us.' Eli commented on how the organ systems in all animals work together 'like the parts of a train' to help them survive in their environment.
We also talked about other animals adapting to our changing environments (birds using traffic light signals to have cars break open their nuts, salmon sensing human pollutants in the ocean and avoiding them).
Then, it was off to the iPads. Some of the students wanted to research their questions (brain size and intelligence, or how salmon actually sniff their way back up a stream). This led us into more discussion about perspective, knowledge, and validity.
Lucy googled 'how do salmon find their way up a stream?' and began reading this article:
http://www.kitabosunnah.com/mir/wonderful-creatures/how-do-salmon-find-their-way.html
I was reading along with her, as we got to this part: "There is only one answer to these questions: Allah, the All-Knowing, created the salmon and the systems that enable them to find their way. Like all creatures, salmon act by the inspiration they receive from Allah and they manifest the Lord's excellent creation."
Salmon acting on inspiration from Allah was something new for us. We compared this with other sources discussing the structure of a salmon's nostils and the unique scent of each current. Because we have quite a few Ismaili students, we were able to learn about the Muslim faith, who Allah is, and how he is viewed as a spiritual God who created the features in each creature. We talked about what a website about salmon might say if it was written by someone who was Jewish, or by someone who was not religious at all. Some students brought up the difficulties of knowing which websites to visit "Which is the best?" "Some have different religions and perspectives. Which should we view?" It was worthwhile to have a discussion about reliable sources and multiple perspectives as it does influence our ability to navigate the world of research through our iPads. We have another day before the break to explore some of these ideas, before we move onto my favourite unit: Space... looking forward to seeing where our inquiries will take us there!
