Transcript of Science Investigation-Mascara

Our presentation was used to test the tolerableness of brand name mascaras to water. In this experiment, we used three very popular and well known waterproof mascaras, and we compared them.
Our problem was "Which brand of mascara is more tolerable to water?" To answer this question, we chose three mascaras, and decided to research them.
These are the mascaras we chose to test and compare:
Paris Voluminous Waterproof Mascara
Make-Up Science
By: Emma Gerlach and Ariana Kravetz
Background Info
- The Covergirl mascara has the lowest amount
of water supply, Maybelline has the second lowest amount, and the Paris has the highest amount of water.
- The three main elements that are used to make mascara are pigments, oils, and waxes
- The lower water is on the ingredients list, the more resistant it is to water.
- If the color of the mascara is black, it has more of a chance to be tolerable to water rather than brown mascaras
If the scientists test which water proof mascara is the most tolerable to water, then the Maybelline Great Lash waterproof mascara would be the most tolerable because, it has the lowest amount of water in it’s ingredients.
1 Paris Voluminous Waterproof Mascara
1 Covergirl LashBlast Waterproof Mascara
1 Maybelline Great Lash waterproof mascara
1 1/4 cup or measuring cup
1 napkin or paper towel
1 Sharpie
1 Washcloth
1 Stopwatch

1. Use water and gently clean skin on arm area that will be used.
2. Draw three "boxes"( about 2 inches wide, 2 inches long,
3. Label the boxes an abbreviation of the name of the mascara used, or label the mascara and then label to boxes.
4. Uncap the first mascara and sweep it in the coordinating box. Make sure it does not touch the edge of the box.
5. Follow instruction 4 with the other two brands of mascara.
6. Pour 1/4 cup of water onto the first mascara. When I first pour, start the stopwatch. Pour another 1/4 cup of water on every 30 seconds. On the last time, wait 30 second then press a dry paper towel on top of the mascara and hold it for 10 seconds. Do this 10 times with each mascara. With each mascara, restart the stop watch, and record observations with every pour.
7. Once the last mascara has had water poured on it and has been dried, observe the different samples.

Independent Variable - brand of mascara
Dependent Variable - how much is mascara leftover on the towel

This is an overall coverage of what the mascara looked like after they were applied to the testers arm.

A = Paris Voluminous Waterproof Mascara

Here, one of the researchers are pouring a 1/4 cup of water onto the first subject.
B = Covergirl LashBlast Waterproof Mascara
In this photo, subject B is being applied to the testers arm. Equal force was used as was used for subject A.
C = Maybelline Great Lash waterproof mascara
This is what subject C looked like after the water was applied and rubbed.

we applied the mascara to different parts of a freshly washed arm, then poured water on each section and then rubbed it with a paper towel to observe smudging.
The results were as follows: the Paris Voluminous Waterproof Mascara was semi-waterproof and dark, and smudged minimally, the Covergirl LashBlast Waterproof Mascara was very light and did not apply easily, and smudged minimally, and the Maybelline Great Lash Waterproof Mascara was dark and smudged slightly. This proves that the last subject was more successful than the other two, proving the hypothesis correct.
Use in the Real World
Because of this experiment, people can now choose the best waterproof mascara and makeup without having to go through other brands and waste money.
We would like to thank Lily Kravetz, for buying the makeup, Juli Gerlach for helping tie together the final report, and Mrs. Hanlon for providing us with this opportunity and for being our teacher.

Thanks for watching:)
