Plastic Bag Education
The idea is to take a random object that is utterly familiar but considered unimportant and use it as an object of learning, finding the connections between that object and ourselves. (Reminds me of Marx's question in Volume One of Capital about how two objects can be made commensurable.)
Step one is just to take the bag and answer the question: What do you see? This step requires time and care, it should be detailed and very specific, a close description, a close reading.
