6 Which Liquid Freezes the Fastest

Which Liquid Freezes the Fastest?

Abigail Pruszinski

Question

I wanted to find out which liquid froze the fastest out of water, vinegar, milk, soda, dish soap, caramel and ketchup

Hypothesis

My hypothesis was that water would freeze the fastest because it has nothing in it to stop it from freezing.

Procedure

• 1. To start off, I poured each liquid into a section of the ice cube tray. To make sure everything was equal, I used measuring spoons.

  2. Then, I put the tray in the freezer and waited every 10, 15, or 30 minutes to check if each liquid was frozen.

1. Every time I checked the tray I took seven toothpicks and poked at each liquid until each one was frozen.

Abstract

This year, I decided to test what liquid freezes the fastest out of soda, dish soap, vinegar, ketchup, water, caramel sauce and milk. My hypothesis was that water would freeze the fastest because it doesn't have anything in it to prevent it from freezing.

To start off my experiment I filled an ice cube tray with each liquid in each section of the tray. I made sure that I measured out each liquid equally. Then I popped it in a freezer and turned on my timer for whatever amount of time my liquids needed to freeze. Every 10, 15, or 30 minutes I would take the tray out of my freezer and used different tooth picks to see if each liquid was frozen or not. I repeated this until, eventually, every liquid was frozen.

For my experiment, I collected a lot of data. Each liquid froze three times in 10, 15 and 30 minutes. Every liquid froze solid by 90 minutes. Water froze in an average of 56.7 minutes. Vinegar froze in an average of 63.3 minutes. Soda had an average of 90 minutes, milk had an average of 86.7 minutes, and dish soap had an average of 93.3 minutes. Caramel and ketchup never ended up freezing. The morning after, I checked the tray and it still ended up not freezing.

Doing this project I learned patience. It was very hard to stop whatever I was doing to check if the liquids froze. My hypothesis was also correct. Although vinegar was only 6.6 minutes slower, water did freeze the fastest overall. A possible way that my experiment was not accurate could have been was the temperature of the freezer. I knew that my freezer was the same temperature the whole time but it could have been switched. If new food was added before one of the tries, the temperature could have been affected. Also the amount of liquid in each section could have an equal amount. I used a measuring spoon to make sure each liquid was equal.
