Ellie (8) asked a question about boiled eggs

Ellie … a very interesting question “We heard hard boiled eggs stand up when you roll them. Is that correct and is there a good way to make it work. We have been unsuccessful.”

I think, if it is possible, it could be something to do with the position of the hard boiled yolk.

I think you have the opportunity of completing a little investigation here with the help of  your parents. Usually an egg will hard boil in a horizontal position. We might therefore need to try to hard boil the eggs in different positions. This may be possible by creating a cradle, suspended from the top of the saucepan, which holds the egg, while it is being boiled. The position of the cradle can then be adjusted to get a range of hard boiled eggs that have been boiled sideways, top down, and bottom down.

To make it a fair test ..very important in science .. you will have to be sure that the egg is fully immersed during the boiling process and that all eggs are boiled for the same time and that all the eggs are about the same. Have I missed anything?

AND MOST IMPORTANTLY YOU MUST GET AN ADULT TO DO THIS AS DEALING WITH BOILING WATER IS VERY DANGEROUS.

All the eggs must then be allowed to cool for the same time before you test them. Again make sure that you roll them fairly. Create a slope using some cardboard and make sure that you start them on the slope at the same place…they will then have the same roll. Also, of course, use the same surface to roll them on.

Finally please let me know what happened. Science is about questions and trying to find answers. You can Leave a Reply in the box below.
