This is a lab that we did in chemistry, with gummy bears. First we measured them and weighed the gummies. Then we put one in salt water, one in water, and one was the control. Then after a few days we came back and measured them again. The results are below here.
This is the before:
This is the after:
An ion is an atom that has a net charge based on a gain or loss of electrons.Â
Ions are formed by adding or subtracting electrons.
Chemistry around us:
This is a lab that we did in chemistry with slime:
The unique physical and chemical properties of a mixture can be changed by varying the amount of each ingredient used to make them.
Slime activators like borax, change the position of the molecules in the glue, in a proccess called cross- linking.
