Constructivism is a key component of the eMINTS model. Basically, the belief is that students learn better when they build their own knowledge from observation and inquiry. However, the challenge is providing adequate experiences that allow for this knowledge construction.
One solution for providing these experiences is YouTube. On a daily basis, users are uploading phenomena that need to be seen in order to understand.
For example, watch the video below…
What do you see?
The video shows a 747 sitting idle on the runway. However, strong winds literally lift the giant plane off the ground. The wind flowing over the wings are enough to slightly lift the plane without any assistance from the plane’s engines.
This is the point where students consider the reasons why this might happen. Ideas about the air flow over the wings would eventually arise. At some point, students would consider the shape of the wings as being a contributing factor. Further discussion may even make connections between the wind and how air moves over the wings when the engines are running.
Student observations (along with some supplemental information about the shape of the wings) would lead to Bernoulli’s Principle. This principle explains how a wing’s shape contributes to lift. Air flows more quickly over the top of the wing thanks to its downward curve. Quicker moving air means lower air pressure. If the pressure on top is less than the pressure below, the plane moves upward. The only difference in the video and a plane actually taking off is that the air is moving due to wind instead jet engines moving the plane through the air.
A video like the one above can demonstrate a complex idea like Bernoulli’s and give students something to which they can connect. This is not the only example found on YouTube. There are countless natural phenomena all over YouTube. It just takes a little searching.
How have you used YouTube to expand your students’ experiences? How have you used YouTube to help students construct knowledge? What other kinds of phenomena could you find on YouTube for this sort of activity?
