In hot water
In order to keep students safe around the hot water bath, there would need to be a temperature control of 50 degrees Celsius.
WHY?
- At 60 degrees celsius it takes 1 second for hot water to cause third degree burns
- At 55 degrees celsius it takes 10 seconds for hot water to cause third degree burns
- At 50 degrees celsius it takes 5 minutes for hot water to cause third degree burns
HOW?
Check with your principal that the school is up to date with the plumbing and drainage act of 2018 which ensures schools have water tempering valves fitted to the water pipeline, resulting in a mix of hot and cold water to a specific temperature limiting the release of water from taps at a maximum of 50 degrees Celsius.
TEACHING - Think of pedagogical strategies in order to teach students the concept of Metamorphic rocks, while keeping them safe from burns and scalds. Modelling the activity, provides a controlled learning environment, while specifying roles to students throughout the explore phase maintains learner engagement.
