 Responding:
1. The first video is about what happens when you put Bromine and Alcohol. The liquid first dissolves, turns yellow, then gets some red flames in it, turns red,starts flaming and dies down. 
2. This video shows what happens when you mix lithium and water. It first starts to flame up then fire starts appearing on it. In the end it just dies down.
3. This video shows what happens when u mix Cesium and water. The Cesium on the spoon just touched the water and creates a red explosion. Just like fire works!
4. This video shows what happens when you mix Potassium and water. A spoon with Potassium on it is put in the water. A black circle appears and gets set on fire. It starts 
to flame and move around then just dies down. 
5. What happens in this video is just that the Sodium and Potassium start to light up and bubble then just die down. 
6. This video shows when you put Liquid Nitrogen into water. A bucket of Liquid Nitrogen is poured into the pool. The pool starts to get foam on it and it spreads through the whole pool. It later dies down and the "foam" is left.
7. This video shows  Aluminum Foil crumpled up into a flask. Its blue and starts to foam up. Later it picks up speed and starts to be gray and hot.
8. This video shows putting a gummy bear into Sodium Chlorate. It just blows up.
9. This video just shows food dye being put into a glass and stirred. Random things are put into the glass and they create different reactions.

***BONUS: What can chemical changes tell us about the elements that are involved in the reaction?
The chemical changes tell us about the elements that are involved by how they react because for example if you use Lithium which is an alkali metal and mix it with water it it will fire up. This shows that alkali metals, alkali earth metals, transition metals, halogens and noble gases have different reactions to things hence this can tell you what element is involved due to its different reaction.
