Today’s class is about climate change and energy.
“Climate change equals an energy problem” is the key point of the class.
Students are making fist-sized EM mud balls.
It’s the first time to make this ball and the smell is bad, so everyone was reluctant to make it.
However, the more they touch it, the more they become to like touch the soft clay.
The mud balls are put into a box and stored in shade for a week.
And then white mold rises. That means it is fermented.
When the mud ball is into the river, water gets fresher and cleaner.
Next class, we will go to the river to throw these mud balls.
