In this experiment we will learn how to make soap. Something to not is that we will be using sodium hydroxide, which is corrosive so make sure you are in a well ventilated room and use your protection gear. 2011 was the International Year of Chemistry and the Chemistry Calendar was set up to spread the word of how chemistry is all around us. The Chemistry Calendar Experiments are linked to the different themes of the Chemistry Calendar videos to give educators and students ideas of how to work with these videos in the classroom. Enjoy!
