1/8 teaspoon of liquit on plastic wrap

                                                       1/8 teaspoon of liquid on the tin foil

1/8 teaspoon of liquid in the pan

                                      1/8 teaspoon of liquid and 1/8 teaspoon of water in the pan

For the two graphs above, it was kind of hard to identify the length and width of the 1/8 drop of liquid because i measured from the picture. So some of them were hard to identify and some where easy.

Liquid	On Cooking Pan	On Cooking Pan with Water	On Plastic Wrap	On Tin Foil
1.       Water	Stayed in circle on the pan	N/A	Began to spread across the plastic wrap	Looks like it gets dried up on the tin foil.
2.       Hydrogen Peroxide	Stayed in a circle on the pan	Separated water and hydrogen peroxide on the pan	Spread a little across the plastic wrap	Spread out on the tin foil
3.       Dish Soap	Had bubbles in the circle when put on the pan.	Began to spread and bubble on the pan	Bubbled but stayed together on plastic wrap	Stayed in same spot and bubbles
4.       Cooking Oil (Vegetable Oil)	Spread  out across the pan	Separated into two different liquids inside one big oval type shape	Spread across the plastic wrap	Spreads out across the tin foil
5.       Baby Oil	Spreads out across the pan and looks like it gets dried out on the pan	Began to separate water and oil	Looks like it dried up on the plastic wrap	Looks like it gets dried up
6.       Vodka	Started spreading on the pan	Couldn’t tell there was water in with the vodka	Stayed together	Stayed together in a circle
7.       Mouth Wash	Spread out a little on the pan	Changed colors	Spread across the pan	Spread across the tin foil
8.       Contact Solution	Stayed in a circle	Stayed in circle on the pan	Stayed in a small circle	Stayed in a small circle
9.       Robitussin	Stayed in one circle clump on the pan	Got a lighter color but stayed together	Stayed together	Stayed together
10.   Ear Care Antiseptic	Spread a little bit on the pan	Stayed in circle on the pan	Stayed in a circle	Spreads out on the pan

Conclusion- Some of the liquids didn't seem effected with the water and some of the liquieds were affected with the way.

Also, when changing surfaces the liquids usually the same as before on the same surface. If the surface spread on the pan it spread on the tin foil ect.

I found this expirment very interesting because it allowed us to see what kind of liquids did what. This would be fun in the classroom as a science experiment and allow the students to make educated guesses of what they think will happen and then show them what happened to see the final result.
