Toasty experiment

Toasty experiment

A tasty and toasty way to investigate your breakfast!

You've slept in, but you really need some breakfast before you leave the house. Which bread toasts fastest, white or brown?

What you need:

  • Slice of white bread
  • Slice of brown bread
  • Toaster
  • Something to spread on your toast - try butter, jam or honey

How to:

  1. Put the slice of white bread in one side of the toaster and the slice of brown bread in the other side of the toaster.
  2. Every 15 seconds, check the bread. Which one toasts fastest?

What's happening?

Brown bread normally toasts faster than white bread. There are two reasons for this:

  1. Brown bread absorbs more heat than white bread. This heat toasts the bread more quickly.
  2. Brown bread contains less water than white bread. Water takes a lot of energy to heat up, so white bread takes longer to toast.

Did you find that brown bread toasts more quickly? If you found that white bread toasted more quickly, it could be that your toaster is toasting the bread unevenly.

Or perhaps one of your slices of bread is fresher than the other. Could that affect your experiment?
