PURPOSE

The purpose of this experiment was going to be to figure out whathappens to the food color dye when when it is added to the followingdifferent temperatures of water and milk: cold water, warm water, hotwater, cold milk, warm milk, and hot milk.

HYPOTHESIS

For my hypothesis, I think that the food dye will dissolve and travelthe fastest in hot milk because the temperature of the milk willdissolve the food dye the fastest, which will make it easier for the dyeto spread throughout the cup and you will see more of a drasticchange with milk since it is white.

VARIABLES

Manipulated Variable: Amount of pressure that is used to release the

food dye into the water and milk from dropper.

Responding Variable: Each droplet will vary in size, this will causes anincrease or decrease in the amount of drops it takes for water or milkto change colors.

Controlled Variable: The amount of milk and water placed in each

cup, which is 8 fl ounces, and the color of the food color dye.

RESULTSIn this experiment, there was three attempts per each temperature

of water and milk. I concluded that the overall experimental results

had a average of 5 to 30 seconds per cup, except for cold and warmmilk because the food dye did not dissolve.-Cold water had an average of 15 to 20 seconds.-Warm water had an average of 5 to 10 seconds.-Hot water had an average of 10 to 15 seconds.-Hot milk had an average of 20 to 30 seconds.

CONCLUSIONWhen conducting this experiment, the main purpose was to try and figure

out what would occur when food dye was added to three different temperatureof milk and water. The purpose was fulfilled because it was concluded through

my data and observations that my hypothesis was wrong. At the beginning, myhypothesis was that the food dye will dissolve and travel the fastest in hot milkbecause the temperature of the milk will dissolve the food dye the fastest,which will make it easier for the dye to spread throughout the cup and you willsee more of a drastic change with milk since it is white. However, I was wrong,the experiment showed that in warm water, the food color dye traveled anddissolved the fastest, NOT in hot milk. This can understood better by seeing

my data tables, graphs, and pictures. In the end, this experiment taught howvolume increases and decreases in temperature.

ABSTRACTThe purpose this experiment is going to be to figure out what

happens to the food when it is that added to the following differenttemperatures of water and milk. As milk and water are heated up, the

volume will increase, but the weight did not. Volume is the space that aobject occupies. All the plastic cups used in this experiment were added3 drops of food dye. The timer was set for 1 minute. The results of thisexperiment varied, because of the pressure, distance, and position thedropper was held in , also, the temperature of the water and milk. Theresults of the experiment showed that the average was 5 to 30 second

for the dye to travel through either the milk or the water. Overall, theresults concluded that food dye affects water and milk in everydaycooking needs.

STEPS &

PROCEDURES Gather 6 clear or glass cups

Label each of the cups with the following names: cold water, warm water, hot water, cold milk, warm milk, and hot milk

Place milk and water in the microwave for 25 seconds, this will be your warm water and milk

Place milk and water in the microwave for 60 seconds, this will be your hot water and milk

Place 8 fluid ounces into each corresponding cup

Align cups in a straight line facing towards you

Add three drops of food color dye into each cup, one at a time, and using your timer, time the speed at which the color dye travelthrough the milk and water.

Record your information

Repeat step #7 three times, each time recording the results

Clean-up after experiment
