Rainbow milk
Rainbow milk
Procedure:
Place a thin coating of milk at the bottom of a dish.
Place 15 drops of dye into the milk
Place 1 Drop of dish soap into the milk
Observe how the colors move throughout the milk.
Continue experiment with 1%, 2% and Whole milk.
Question:
Does the amount of milk affect how the food dye moves throughout a dish of milk?
Hypothesis:
I believe that the more milk there is in a given object, the faster the food dye will move throughout the dish.
Conclusion:
It is clear that through my observation of the experiment, the more milk fat the milk has, the more movement there is with the dye when the dish soap is added. The amount of dye makes no difference and when the soap is added in large amounts there is no change in the movement of the milk. The only variable different in the experiments was the amount of fat in each type of milk. Therefore I believe that it is the milk fat that reacts with the dish detergent to cause the reaction.
abstract:
I chose to research how dish detergent and food dye react to milks with different amounts of milkfat. I chose this because I had done this experiment before and wondered what caused the reaction between the milk and detergent, and whether different milks would have the same effect. My hypothesis was that the more milkfat in a given object, the greater the reaction between the detergent and the milk. The greater the reaction, the faster the food dye will move throughout the dish.
The tests took place in Mr. Mason’s classroom. Only two people were present myself and Mr. Mason. Trays, food dye, and milk were gathered and brought into the classroom. Trays were set out and each filled with a milk with a different fat content. The four milk choices were 1% milk, 2% milk, whole milk, and half and half. Next, four trays were laid out and each was filled 1 inch high with a different milk. Exactly 15 drops of food dye were added to each tray. One drop of dish detergent was added to each tray one at a time and the reaction was observed for at least 10 seconds. During this time notes were taken on how the detergent and milk reacted. After all the experiments were complete, pictures were taken to show proof of experimental result. Last, materials were safely disposed of in proper receptacles. Date was collected by visually observing how quickly the food dye moved throughout the tray of milk. The faster the movement, the greater the reaction between the two substances.
Throughout the first test it was clear that 2% milk and whole milk, had the greatest reaction. It was difficult to observe, but the colors moved continually throughout the milk over the 10 second period. This test was inconclusive as to whether or not whole milk or 2% milk showed a greater reaction, but it was clear that the 1% milk showed a much weaker reaction that the other two. During the second test, half and half was added in a curiosity as to whether it would have a greater reaction. Clearly in the second experiment, whole milk clearly had the largest reaction with the detergent. Half and half had practically no reaction as the food dye stayed in place when the detergent was added. 1% continued to show little to no reaction. When dye was added to the whole milk, the colors sprang throughout the tray, creating a swirl of colors as seen in the pictures.
Through this project it is clear that through observation, the greater the amount of fat the milk has, the more movement the dye has throughout the container. Every other variable stayed the same except the amount of fat in the milk. Therefore it had to be the amount of fat that was in the type of milk that created this reaction. This clearly proves my hypothesis that the more fat the milk contains, the greater the reaction between the milk and the detergent. We could have changed different variables to be sure of the accuracy of the experiment.

what my science fair what i will be testing is how dye and milk and dish detergent will react with each other.
Dropped 15 drops into pan of 6 oz of 2% milk first. Added 1 drop of dish soap to the pan. The colors exploded and moved throughout the pan. Next I added 6 oz of whole milk to a similar sized pan. I dropped one drop of dish detergent into the pan. The colors moved, but at a slower pace than the 2% milk. The colors did not mix as much as they did with the 2% milk. Last, 6 oz of 1 % milk was added to the pan. 1 drop of dish soap was added. The milk moved faster than the whole milk, but not as fast as the 2% milk.
Test #2
Dropped 15 drops of food dye into a shallow pan with half and half milk added to the bottom. Dish detergent was dropped into the pan and the colors moved slowly throughout the pan. Next we added 1% milk into the shallow pan, added the 15 drops into the pan and added the dish detergent. The colors moved slightly throughout the pan. Clearly at a faster rate than the half and half. Next 2 % milk was added and when the detergent was added to the pan the colors exploded at a faster rate. The colors moved in a wave pattern. Last, whole milk was added to the pan. The 15 drops were added and the detergent was dropped into the pan. The whole milk clearly had the largest reaction. The colors flew away from the area where the dye was placed.
