On Friday we finished working on the concept of density. Explain why you think the two units used (grams and mL or cubic centimeters) are appropriate for density's formula. What real life applications could density be used for? Explain (Do not use the example we discussed in class)

Well they have to deal with matter thats why.
They are used for experiments with diffrent things.Like the oil spill,the oil floats up to the surface cause it has less density. :)
Because density isn't length, so grams and mL work. An example is if you throw a rock into the water, it'll sink to the bottom because theres more density.
You have to use those measurments it deals with weight.
there used to weight and measure mass.If we dont have them we will not know how much people weigh in the world we wont know what items weight to see if we can carry them our selves.
Cause they deal with matter. We learn it to tell how denes somthing is. We use ML to tell how much liquid can fit in a contanor. Thats why i think its important to know density.
The oil spill. Thats a real life situation. Since the density of the oil is less than one, the oil floats to the top. If the density were to be more than one, the oil would sink to the bottom.
Density is expressed in grams and cubic centimeters because if you broke down a three dimentional object you would break it down its smaller cubes. You break it down into cubes because it it easy to measure. A real life example of density is like floating candles the candles would have less density than the liquid they float in and if they didn't they wouldn't float.
