Collision theory says that a chemical reaction can only happen when particles bang into each other!
Can you give us an example?!
Absolutely! lets talk about chemical reaction of water!
Chemical equation: H2 + O = H2O
When water molecules and hydrogen molecules collide into each other they form WATER! But there are some exceptions.

If the molecules follow this criteria they will form a bond!
1. The collision must have enough energy to break bonds holding reactant molecules together2. Reacting molecules must collide in a proper orientation to form a new bond
Now we know all the science stuff, how does this relate in real life?
You can't make an omelet without cracking the egg.Cracking this egg is like breaking bonds and forming this omelet is the product.
ohhh I understand better now! but do you really want to eat that cafeteria omelet?
How did she change so fast? why are we out here?
If molecules want to react with each other to form a product they have to fit together like a puzzle piece to succeed.For example if my foot and this ball don't collide perfectly together I won't make this goal!
That's awesome! So molecules are like Legos and only fit one way to form something new!
Another thing about collisions! the more molecules the higher chance they will collide and they will use less energy to produce a product!Like the more people you are around the more people you will make connections with and make friends! with using less of your energy! Yay!
Is she saying we need to make more friends?
Less energy is always good!
Molecules need energy to break apart and energy to form new bonds
What did you learn?
The more molecules around the higher chance there will be collisions
Molecules need to be in the right orientation in order to collide
