Lab: Colour

Activity A:
 1. look at the monitor
 2. r+g, r+b, b+g
 3.  work with another group—put a color paddle over flashlight, shine on white paper—so a red, a green, and a blue
 Activity b
 3.  view white paper through color paddles—record results
 4.  view colored objects through color paddles
 5.  if you have time, do activity b—color by subtraction--

milk lab

questions

1)  why do we add salt to the ice?
      Salt decreases the temperature which helps it cools easier.
2)  why do we add the cookies and other things, only after the milk has frozen slightly?
      It will make the frozen milk tastier.
3)  what are two factors that affect the freezing you think?
      Ice and salt
4)  why do you need a bit of air in the bag?
      In my opinion, the air inside will be the space when milk vibrates and air can change the temperature inside easier.

calculate the density of each of your mineral samples. How could you use the densities to identify the minerals?
If the densities are the same, the objects are the same. If the densities aren't same, the objects are different.
Key Concept Would density or color be more useful in identifying a particular mineral? Explain your answer.
I think density is more useful, it is more accurate becuase it will be the same ratio but one mineral can be more than one color.

WRITING ASSIGNMENT

                       Acid rain is the rain which is acidic and ph of acid rain is 4.3 but clear rain is 5.6 It can be harmful to fish and others wildlife. Plants may die if that area has acid rain. Acid rain will make stone change the shape. Acid rain is very dangerous, plants will die and we won't have oxygen. So we will die later.
