What a great experiment! Congratulations on your son’s hard work and his award. I’d love to see the pictures, if you’d like to share. (Email me at scienceideas AT….. 24hourscienceprojects.com .)

My son just won first place with his ice melting science project- what liquid will melt ice the fastest.
We used household ice, 7-11 ice and sonic ice. We used water, orange juice, apple juice, coke zero and regular coke.
We measured the speed at room temperature and at chilled temperature.

take lots of pictures and use good graphing!

The formula for this is 2 times pi (you can use 3.14) times the radius times the height of the piece of ice PLUS 2 times pi times the radius squared. In mathematical terms, it is: (2 x PI x r x H) + (2 x PI x (r x r)) . Don’t worry – it isn’t quite so hard to do as it looks!

BTW – Inside the 24 Hour Science Project guide is a spreadsheet that will calculate this for you automatically.

Have fun with your project!

im doing my project on does the shape of ice affect its melting point but how wouldi calculate the surface area to volume ratio of my different shapes of ice before i begin melting it at the sane room temperature

Hello Gabrielle,

Thanks for your purchase. We had a great time doing this project. My first hint is that you do just a bit of reading about ice and melting. You can start with the references we provide in the guide. Then, write down your hypothesis: does the shape of ice affect melting time – or not? Use what you know to decide.

Get your supplies together next. You shouldn’t have to spend a lot of money on this project; ask your pharmacist to help you get the medicine bottles for the cylinder.

One of the things that’s really important about this project is measuring the ice correctly – and putting the data in the correct column! A couple of kids have accidentally switched the height and diameter, which doesn’t work.

Have fun with your project, and please let us know how it turns out!

Hi,

I have chosen to do my science project based on the problem statement:

Does the shape of ice affect melting time?

I would appreciate any tips, advice, and information you can give me on this. I am in the fifth grade and I would like to do a good job on this.

Thanks so much for your help!

Sincerely,

Gabriella
