Sagot :

Hi :) Some of the typical investigatory projects which are proposed in Research subjects are therapeutic compound or health benefits of plants around us. Well, i suggest try using egg shell as a substitute chalk. I proposed this because i'm allergic to chalk and egg shell has also the same compounds as chalk (calcium carbonate).
