Wow nice brood
What other species ur fren have?
Anw, u might wanna ask him to change the substrate to coco fiber 

Kid ka? All of us here also kid lol
Tell him la, this kind of scorp need to be in humid environment
Gravel liddat cannot absorb water and maintain humidity
Coco fiber absorb water more effective and can support burrow
If he refuse, tell his mother

2lizard eating babies? What the hell is going on in the enclosure?
Did he house it with a lizard or something? 
From the pic u posted, they have all molted to 2instar, they will climb down from the mom soon
U can remove them after they all climb down from the mom or leave them with the mom, u decide...
Wont harm the babies as long as u removed them after they climb down from the mom
Anw, do explain the lizard.....

oh man.. he should hav wait till the babies climb down from the mother's back then you can remove them.. coz they already 2instar then there is a possibility they will make it through but having he removed them before it climb down on it own then that my friend is not good.
But thats just me. as for the opened top.. ask im to place something heavy on the tank.. but make sure there are gap so that the scorp can breath. Or get those garden wires and make a lid for ur self. I did that wen i started the hobby.

Kesian... Being kept as if it's a desert sp....
Change the substrate, get a enclosure with a secure lid and do more research
Ask him come here and read the 1st page or best, ask him sell the whole brood with the mom to someone who can take care them better
I just lost an entire brood of babies because i removed them from the mom before they climb down
A guy told me during their time on the mom's back, those babies receive nutrient transfer from the mom's back and separating them too early could lead to death or a weak brood
Can u possibly give me his contact like msn or anything so i can talk2 him

Well, we just do our part and hope for the best
Depend on how long he have separated them, if only a few hours, yes, they ll climb back on the mom

Swt...he is just 14 and I hardly seen any 14 that is mature enough to do his own research(even homework also copy frm fren ),but we can only advice him how to take good care of scorpions,the rest is up to him to decide.
Of course if he still insist in the way he is keeping,then he should let go of the babies for better homes.
So,will he takes in advices?

You could try with one or two babies and see wut happen..
