Exploring color

When the red lens and green lens has been shining by the light the color get yellow but when red and blue combine it gets the pink color. The last result is when blue and green combine that will get very dark green.

Another thing that we know is when the original lens pass through the paper the lens will allow only there own color so we see only the color of the lens in the paper other colors will be absorbed or reflect out.

crystallization of milk

1)  why do we add salt to the ice?
That will make the ice lower degree lower temperature so it can freeze the milk quickly

2)   why do we add the cookies and other things, only after the milk has frozen slightly?
It is difficult to put the thing before milk has frozen because it will freeze slowly

3)  what are two factors that affect the freezing you think?
salt that is solute when salt dissolve in water because salt make particle harder to come join close together and sometime this happen in sugar

4)  why do you need a bit of air in the bag?
The air will help easily from ice and freeze it to milk to become ice-cream

Answer question for lab

You can use the density to define material by using water displacement method to calculate density by finding mass then divide by the volume of the water

I think the density and the color are both useful because we can identify the mineral by seeing the color and looking for the same of it and the density can be used to know the mineral that heavy or light then you can compare it.
