Introduction: PH BattleShips

By

this is a fun way to introduce chemistry students to the subject of pH.

Step 1: Setting Up

each student sets up a square field of centrifuge tubes.
I would recommend a 5x5 field because filling 25 tubes is a reasonable task.


Step 2: Filling the Tubes

in a 5x5 field you would like to create 4 ships
1x fishing boat 1 tube 
2x patrol boat 2 tubes 
1x cruiser 3 tubes 
fill these with a liquid with a pH higher than 8 ( soapy water) 


that leaves 17 tubes which can be filled with highly diluted vinegar.   

Step 3: Ammo

use Litmus as ammunition.
this will cause a correct guess to turn blue and an incorrect one red.

Step 4: Let the Game Begin

let the students play against each other!
