With wide eyes and open mouths, we watched as Mr Yu used a range of materials to make loud popping noises and to change the colour of fire on a Bunsen burner.
The Secondary School has been collaborating with Pre-Primary to learn some Chemistry.
Mr Yu began with a quiz. He asked us what we had seen on our journey and we came up with a range of answers, including the playgrounds, trees, plants, and other classrooms. We were then given the opportunity to observe and participate in a range of science experiments. With wide eyes and open mouths, we watched as Mr Yu used a range of materials to make loud popping noises and to change the colour of fire on a Bunsen burner.
We learned to use our senses to detect changes in a chemical reaction. We got to add reagents one by one, and saw the colour change, gas bubbling, and even felt coldness and heat as the chemicals reacted!
Then we had a chance to make an instant cold pack using things you could use around your house. In the activity, we added another chemical to the cold pack which immediately turned it into a nice hand-warming heat pack.
The workshop finished with an important spiritual lesson to take home:
Sometimes sad things happen in our lives, very much like a cold shower to our hearts. As we seek God in prayer, He may not always answer it in the way we expect or by removing the trials straight away. Nevertheless, His grace is sufficient for our lives, and is able to warm up our cold hearts.
‘But He said to me, “My grace is sufficient for you, for my power is made perfect in weakness.'” (2 Corinthians 12:9)
Thank you Mr Yu for giving us a taste of how wonderful Secondary School is going to be!
