The project being done is called Old Foamy. This experiment can be related to history class in many different ways. The project what most people know as elephant toothpaste, and as everyone knows, it expands. At the beginning it is just powder, but after adding the sodium iodine solution, it expands. This can be related to history because it can show how population explosion happened.

During the beginning of history, population was growing at a very slow rate. This was a result of more technologies, and longer life expectancy. The population has exploded right after the Plague, in the Modern Age. The population mainly exploded after World War II. This is shown in the project when the hydrogen peroxide and soap are added to the beaker, slowly increasing the amount of liquid. Then, as the sodium iodine solution is added, causing the liquid to expand.

This project also shows another thing about population explosion, which is carrying capacity. When the world gets too populated, it will reach it's carrying capacity. This is shown by when the foam made by the chemical reactions comes out of the beaker. This will also happen if the world gets too populated, people will not have enough resources to sustain life on earth. This is also happening in many countries making them overpopulated.
