2nd Grade, First Principles

"A first principle is a basic, foundational, self-evident proposition or assumption that cannot be deduced from any other proposition or assumption" -Quora

This week students in 2nd grade at St. Raymond experimented with LEDs (Light Emitting Diodes) and coincell batteries. Students in 2nd grade already know a surprising amount of First Principles. Students can not define what a volt or an LED is at the start of class, but they can tell you that you would need more the one 3 volt battery to light up a 5 volt LED. A lot of learning is actually just putting names or labels to things we already knew.

2nd grade students know that electricity has to flow from somewhere to somewhere, today they simply put a name to those places: positive and negative (+/-). 

2nd grade students already know that working together they can archive more. Today they learned that combining their own 3 volt battery with a neighbor's 3 volt battery they can make a 5 volt LED shine brighter than they could than on their own: "We shine brighter together" - The ultimate first principal?

A 5volt LED shines a lot brighter when you combine your 3 volt battery with your friend's 3 volt battery
