My son was 2 years old and loved those door stoppers that went twang. You know those coiled thingies with the white rubber cap. They drove me crazy! He would lie on his belly, flat on the floor, and pull them all the way back and let them go wild! He would laugh and laugh! The sound drove me crazy enough that I wanted to remove them all. But I didn’t, because my son seemed to love the resultant noise and motion.
Here is the email he sent me last night. (He is an unschooler that is now taking engineering.) “Hey Mom, These days I’m doing analysis on oscillating machines, like a door stopper. You know the spring ones where you pull it to the side and it goes dwawawwawanngg? Who’d have thought I’d be doing the same thing today in school as I was doing 22 years ago….”
Sometimes the simplest toy or household item is the best learning experience. Unschooling STEM does not have to be expensive. Experiential learning in the early years gives way to greater theoretical understanding in the later teenager years. Feed their curiosity and say Yes to their exploration. (But don’t forget the earplugs!)
