This is a great Christmas science activity or for World Book Day to sit alongside reading The Gingerbread Man or Hansel and Gretel.

It’s also a brilliant Christmas baking STEM challenge! Challenge your friends to make a house and test to see whose is the strongest!

Gingerbread house STEM Challenge - this would be great for a Christmas STEM Challenge too.

If you don’t fancy baking the gingerbread an easier idea is to use square biscuits in a tent like shape.

Ask the children to make predictions drawing on existing knowledge as to which substance will hold the house together most effectively.

This is also a great activity for practising designing a fair test and carrying our correct experimental procedures.

How to make a Gingerbread House

Gingerbread House

Gingerbread pieces

Icing sugar / marshmallow fluff / royal icing / liquid glucose


Investigation Instructions

The easiest way to do this is to bake a thin sheet of gingerbread and use cutters to cut immediately after taking out of the oven. This ensures all the pieces are exactly the same size.

We used two squares and two smaller rectangles, but you could use any shape you wanted.

Build a gingerbread house for each type of sticky substance you are testing. Try to use a similar amount for each wall on each house.

Leave overnight to harden.

How to test for strength

Pick up the house and see if it stays intact.

Roll a marble or small ball at the house. Does it fall over?

Performing simple tests

Using scientific language to answer a question describing how to carry out a fair test.

If you don’t want to bake, try using three rectangular biscuits. You could even give them to friends as gifts.

Another idea is to add some edible glass to your gingerbread house. The easiest way to do this is to cut out a window shape before baking and place a clear mint or two inside. The mint will melt and look like a window!
