leaRNING Chemistry with Dr. Han 1.9.2018
Dr. Han opened this evening with a chemistry experiment. He had small ribbons of magnesium and lit them on fire. They burned a very white, bright light. He did this several times for the children to observe the chemical reaction between the magnesium and the fire.
He then showed a short video of fireworks on display and discussed how each different color represented a different element, such as magnesium which burns white, copper which burns green, etc. The color of the firework is determined by what element is inside of it.
He also discussed what elements are. Everything in the universe is made up of elements. If we break down an element and keep reducing it to a smaller and smaller version of itself, we will finally arrive to the smallest part, which is an atom. No two elements are the same, but atoms can be combined to create a whole new element.
