Materials

Take a much closer look at this everyday object. Can your class use their reasoning skills to work out what it is?

Run the activity

You will be zooming in and out of the image above – starting very close and stepping back slowly.

1. Start by asking everyone:

  • What do they think the image is and why?
  • What does the image remind them of and why?

2. Every time you zoom out, ask the class:

  • Can they describe the colours, shapes and textures?
  • What do they think the image is now – have they changed their minds?

Background science

Lots of the breads we eat are made from three simple ingredients: flour, yeast and water. Bread gets its rise and spongy texture because of yeast, a living organism that produces carbon dioxide when it feeds off sugars in the flour. This creates the holes in the bread that makes it light and airy. Leaving the dough to rise or 'prove' makes it even lighter, baking then kills off the yeast.

Take it further

Do your pupils eat bread at home? What kind of bread do they eat? This BBC video shows the bread-making process from start to finish. Why not try making some bread with your class? STEM Learning has a great activity to help.
