Question: What will happen when you mix dish soap with milk and food coloring?
Hypothesis: We think that the dish soap will make the colors spread out around the outside of the plate!!
We do not ask for much, just 2 simple rules so everyone has a safe and enjoyable time!
- Please do not put anything in your mouth, we do not have eating or test tasting involved!
- Please do not wreck any materials, for we want everyone to have the same amount of fun as you did!
All kids will have an opportunity to participate in the experiment.
- First, pour the milk in the plate, make sure that it covers the base of the plate.
- Next, take some different color food coloring and pour 2 drops per color.
- After take a Q-tip and dip it in your soap.
- Lastly, with the soap on the Q-tip press it in the middle of the plate.
Then you will find you conclusion!
The reason the conclusion is what it is, is because of surface tension. The milk and food coloring have surface tension. The dish soap brakes up the surface tension and makes it burst out!
Question: What Is Surface Tension?
Answer: The tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk or the liquid, which tends to minimize surface area.
From this experiment, we learned that the soap will break up the surface tension of the milk, causing the .
Hi, my name is Natalie, I am 10 years old and enjoy soccer, basket ball and especially science that is why I love science night and I hope you like my experiment as much as I do!
Hi, my name is Gretchen and I am 10 years old, I love dance, science and basketball, I had so much fun doing my project and I hope you like our experiment as much as I do!
Procedure: Will there be enough of an opportunity for all participants to be able to add coloring to the milk? Maybe have 4-5 plates set up per group, so everyone has an opportunity.
