ok,im having a science fair and im doing, which food wrap (aluminum foil,plastic wrap, or sandwich bag) can spoil food the fastest?i think its a good topic,but what should i use,my control? could it beapples?bananas?please help me! PLEASE! thank you!
My suggestion would be to use two or three controls! Start the experiment with 3 things that might be found in a school lunch - maybe: Ham, Cheese (spoils fast), apple slicesPut each of these things in the same wrapping (and also again with no wrapping), and see which wrap works best with each food itemYou'll have a lot of cool graphs to drawGood luck!!
It is called pica which is an abnormal eating of undigestible objectsI usually indicates stressLike people biting fingernailsIt could be dangerous if she swallows something that could block her digestive tractDon't yell at herJust get up and remove the object and give her a substitute toy to chew ongood luck
I would be willing to bet that more than misbehavior or pica, she might be having some teething issues uld she be losing some baby teeth? Look in her mouth or have the vet check her teethJust a thought.
