Decoding the Universe - Secret Picture

What is coding and how does it work? In its most basic form, coding is simply a set of instructions used to inform or teach a computer what to do in a way that it understands. There are all sorts of codes that we use as humans to communicate with each other as well. Use the colour/direction code in our template to draw and reveal the secret picture, then create your own code and secret picture for your friends and family!

This is a great activity to complete during National Science Week 2025!

  • Step 1Download and print the template provided. We recommend using cover paper as this provides a sturdy surface for decoding.
  • Step 2Begin to draw in the grid following the instructions and code on the template.
  • Step 3When you have followed the instructions on the template correctly, the outline of the secret picture will be revealed! Colour and decorate your outline, then cut it out the completed image for display. Adult supervision is recommended when using scissors.
  • Step 4Now you understand how coding works, use the blank template on page 2 to plan and create your own secret drawing for your friends and family to solve!
