Who would have thought a set of magnetic shapes would open the door for so much learning. For me and Spencer, we walked through the door together and learned about each other too!
He is interested in building functional structures. In this case, he wanted a garage for his Lamborghini Murcielago. A two level structure was important to store multiple vehicles, but the most prized possession goes on the second floor. In this case, security is extremely important, so a drawbridge sort of ramp was created that rises to prevent entrance from below.
He discovered that the drawbridge would not completely close because the magnets on the structure were pushing it away. “I wonder why?” turned into “Wouldn’t that be cool if a real garage could have that?” as we talked about North and South magnetic fields…opposites attract, likes repel, the conversation deepened. “The force is really strong.” brought us to talk about an exciting real-world use of strong magnetic fields: Maglevs (Magnetic Levitation Trains). We discovered that a Maglev hovers 10mm above the concrete path. We went to a website to convert 10 mm to .393 inches (I swear they told us in 5th grade that the English measurement system was being replaced!)
“Ah! Maybe this magnetic field could also be used as security against attacks?” moved us further into another discussion about “What if soldiers could wear magnetic fields instead of bullet-proof vests?” that led to a discovery that not all metals would be stopped.
I pointed out the difference between the hinge-joint and the ball-and-socket type joint in different areas of his structure. Then I pointed out a ball and socket joint in the shoulder. “Where else do we have these types of joints?” became a mini lesson in why people sometimes need surgery such as hip replacement or rotator cuff repair.
To his dismay, he was short on square pieces to finish a few details. Stability in architecture became evident as the walls wanted to collapse inward as he tried to remove the divider floor. He did notice the triangle shaped pieces sitting in front of him. “I wonder how many triangles it takes to make a square?” he asks. All he had were equilateral triangles that connected at the points….so this question was actually more difficult as it appeared.
Once the door were on and he was satisfied with security he declares, :This is as secure as Fort Knox!” , an expression with which he was familiar, however he didn’t know what Fort Knox was! We looked that up too. Which brought us to the discussion about how money is backed by gold. (and the fact that there is a Fort Knox in Maine that is different than the Ft. Knox in Kentucky!)
Through it all, his level of “knowing” deepened. We explored anatomy, economics, history, science, math. We had a great time Skyping each other links from our discover research. What fun!
Where is he now? In his “office” with his laptop. We are no longer in the same room. His search for Fort Knox has led him on an adventure through wikipedia where he is exploring his real love…Apache Helicopters. The skype links keep coming…for those who question if technology replaces “real human connection”…I am more connected to my son at this very moment than I could ever have imagined possible. Our minds are working in tandem and the energy is very high.
Learning through play is not a new concept. This was just another confirmation of the value of discovery learning, relevancy,
timing, connection of ideas…cued off the learner’s energy that was
sustained during the course of 2 days for a total of 6+ hours. His last
question before my post? “Can we go to Walmart to get more magnets?”.
