Turn on scale. Make sure scale is balanced (press zero if not) then place crucible + lid onto it to find the mass.

After finding the mass of the crucible + lid either you or your teacher should add a tea spoon of the hydrate (epsom salt) into the crucible.

In order to find the mass of the hydrate you must take the mass of crucible + lid w/ the hydrate and subtract the mass of crucible + lid.

28.77g - 26.11g = 2.66g

Have your teacher ignite the fire before you begin to heat the hydrate. Leave the lid of the crucible slightly ajar. Heat hydrate on a low fire for four minutes. When the four minutes is up heat hydrate on a higher fire for ten minutes.

After heating the hydrate for 14 minutes allow it to cool for atleast five minutes. Place it on a steel ____. DO NOT TOUCH IT!
