Acid rain

Today we talked about how acid rain occurs and what the effects of the wild are and what we can do to improve the environment in the future. We made a small scene to show how acid rain arises and ends up in lakes and forests. 

We also did a theater of this, where Johan talks about how acid rain is formed and ends up in lakes. Emils mission was to save the lake and so he did by pouring chalk into the lake, to set up a bass. "Save the Lake" is what Hans Persson called the exercise in his book "Experiments with chemistry." 

A super fun conclusion to the lesson and no one will forget what acid rain does:)
