Another fun and exciting lab~

Today we did another lab to see how to separate solutions in full action. At first Ms Chen told us to get all the equiptments that we need then we all had to WEAR OUR SAFETY GOGGLES ( Always have safe even when we are dealing with food dye. There might be a chance for it to accidentally color our eyes). As we moved on with the lab we all had 3 pieces of paper and we had to cut the piece of paper in to a pencil shape. Then with a pencil we marked a line 4 cm from the tip. Then the fun part begins we filled the test tubes with 2 cm of water and got a drop of food dye with the color of our choice (red yellow blue, BLUE FTW!!!) from Ms Chen. We put the chromatograph with a dot from the food dye into the test tubes. When we are finish the food coloring that Ms Chen give us we had to record it on the board and get new colors (Unknown and green) from the back.


After 20 minutes the food dye finish separating and the end results is food coloring that have been separated into it original colors.  After we pretty spent the rest of the time doing the lab questions...
