1)Is it better to use a bowl or a container to make gelatin?
2)Does it matter what kind of water I use to make gelatin? Or is it better to use faucet or purified water?
3)Where do you work?
4)Is there anything you suggest me that I should include to supplement my background for my experiment on gelatin?

Answer 1:

I like your science project.

1. You can make gelatin in a bowl or container. For a science experiment, I recommend making the gelatin in a container with a flat bottom. It would be nice to have several flat bottomed containers of the same size for making different batches of gelatin at the same time, for a science project. I think the material of the container will make only a little difference in the time it takes the gelatin to harden. A heavy glass container might cool more slowly in the refrigerator

2. You can use any kind of water for the gelatin. Jello has gelatin, and there's no rule about what type of water to use. Jello also has lots of sugar and colors and flavors. It would be interesting to see what differences you get with more or less gelatin. For example, how long does it take gelatin to harden with lot of gelatin vs. a little gelatin in the water? How stiff is the gelatin after it hardens? Maybe you could measure that by seeing how many quarters you could stack in a tower on the gelatin before they started falling in.

3. I used to work in the Physics Department at the University of California at Santa Barbara, but now I'm retired. I still do a little work on the origin of life.

4. Here's a web site with gelatin experiments; the tab labeled 'Background' has good things to read and include in the background for your project. Gel Well: Which Additives Make the Strongest Gelatin?

Gelatin! It's hard to think of another food that is used as frequently on the dinner table ... To determine how additives-like acids, sugars, salt, and milk-affect the ...
