In this lesson, my students have been studying the air and some of its components: nitrogen, oxygen and carbon dioxide.

We have watched a couple of videos about how to create carbon dioxide: if you mix baking soda and vinegar, you will obtain carbon dioxide, water and a salt (sodium acetate).

In art, we have prepared volcanoes with a plastic bottle, cardboard and newspapers. Some of my students have record themselves doing this experiment at home.

Here you are the videos. I hope you like them because they are great!!
