Before explaining this Density Lab. There is one important question: WHAT IS DENSITY?
Density of a substance is its mass times volume. In this lab, we made colors appear in the same cup, but not mix together.

For our density lab we had to have certain materials. The materials were:
-SCALE
-THIN STIRRING ROD
- YELLOW/BLUE FOOD COLORING
- A BEAKER WITH HOT WATER (250 ML)
- A BEAKER WITH COLD WATER (250 ML)

-THIN STIRRING ROD
- YELLOW/BLUE FOOD COLORING
- A BEAKER WITH HOT WATER (250 ML)
- A BEAKER WITH COLD WATER (250 ML)
W first weighed both empty beakers we got. One beaker was 116.3 grams and the other beaker weighed 116 grams. Then, we measured 250 mL of cold water and poured it into one beaker and then we poured 250 mL of warm water into the other beaker.
Then, we added 20 grams of salt and poured five drops of blue food coloring into one beaker. We used the stirring rod to mix it up until the salt mixed up. After, we poured other five drops of yellow food coloring into the other beaker. Next, we weighed both beakers with water, salt, and food coloring inside. For the first beaker, the mass was 323.5 grams. For the second beaker, the mass was 299.2 grams.

PART 2
We poured the warm water from beaker one in a bigger beaker that was 500 mL. Then, we put the cold water from the other beaker into the other beaker. Then we got a THERMOCLINE. We created three different layers of density. On the top layer, we had yellow warm water, and underneath that, we had a green dense water, and beneath all that we had a dark blue water. Since the blue water is dense, it sinks to the bottom. The green dyed water is not that much as the blue so it stays in the middle. The yellow dyed water is not dense so it stays at the top. As we continued to pour more water into the bigger beaker, we found out that the yellow water decreased more and more as we poured. The blue turned green. And the green the green layer increased filling almost the full beaker

THERMOCLINE- A thin layer in a big body of fluid in which temperature changes quickly
