Today the 6th graders were going to do a plant experiment - How does the amount of soil affect the growth of a plant?
I had 2 periods for the lab and I started out with them weighing the empty plant pots.
I soon found out none of them had ever used a triple beam balance before. Two periods and a part of their lunch period later the last team finished weighing the mass of the pots with soil.
Not only were they struggling with the mechanics of the balance, but many had trouble adding the amounts from the 3 balancing beams (100 + 40 + 7.5 = ??)
Is it too late for me to get good at skill analysis?
