Create your own SODIS timer in 3 main steps:

icons of 3 building blocks (cube, corner connector, and short frame)

Step 1

Build the SODIS timer by attaching your micro:bit to a water bottle.

Icons of code blocks.

Step 2

Add code to bring it to life.

Step 3

Use and test out the timer to learn how it works.

SUCCESS CRITERIA

I can:

  • build a SODIS timer using the micro:bit
  • explain how the micro:bit senses light in its environment
  • explain how variables, conditional statements and loops help track how long a water bottle has been in the sun
