With this lab I was able to determine and execute the proper separation of a mixture of solids through various means‚ such as evaporation and filtration. Using these techniques presented the separation of different ingredients from a mixture was conducted based upon the usage of individual physical properties of each substance presented in the mixture. . Observations: Throughout this experiment I noted several things

It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided to experiment and put in the yellow solution. The second we put the yellow mixture in‚ it immediately mixed in with
