The reason why I did not combined the two chapters was that this practical worksheet goes much deeper into the facts. We were to burn a magnesium ribbon but we were told not to stare into the fire. The ribbon glowed so brightly that you could turn blind! After burning, the magnesium ribbon turned into a grey ash and it was fragile and powdery. We were told that a new substance has formed. Then we learnt how to write word equation.
After that, we were to react an element with a compound. We added iron fillings with dilute sulphuric acid and bubbles formed as well as the test tube turning quite hot. Then we were to react two compounds. We mixed sodium chloride solution and lead(II) nitrate and a white solid forms! Then as a class, we discussed about the difference between metals and non-metals.
At home, I collected several materials and I tried to burn them together with the help of a parent. It was quite fun as the material became ash and I dirtied my hands by touching the ash.
