STEM secret messaging challenge 📩

Today we gathered some everyday household items and got ready to try some alternative ways of messaging.

Firstly, we looked at how we could use objects to make images of words or phrases.

Then we used some special solutions to investigate what would make the best invisible ink.

Our grand finale was making Morse Code strips from basic items like string, straws, pasta, polos, buttons or beads.

The dashes and dots system is great for making messages!

Here is an example with red tape to space between letters.

Can you make a better example with your name?
