Details: Snotlout has run out of energy! Talk to him to find out more about energy and dragon fire.
Snotlout
I can't do it anymore. I can't take it! Snotlout Jorgenson is undervalued and underappreciated at the Training Grounds! They expect me to slave away all day and not take a single rest. All my energy is gone. I'm out of energy!
Heather can save me! Will you ask her if she can make me something to boost me up with some new energy?
1- Talk to Heather at the school
Heather
Is Snotlout complaining again about his workload? I hope he's not falling sick, but I doubt it. If you ask me, I think he's just trying to look good in front of us by pretending to have a lot of duties!
That's a very interesting phrase he used: "all my energy is gone." The interesting thing about that is that energy can never be fully lost. Instead, it changes forms and becomes a new type of energy.
(I'm nitpicking. I know that he meant that he's tired, but this is a great opportunity to play with some dragons!) Go to the Lookout for a fun exercise.
2- Go to the lookout
Heather
I got a bunch of friendly dragon helpers to show us the different forms of energy!
Energy is the ability to do work, and it's used by everything from the smallest plant to the largest dragon. Think of it as the fuel that keeps everything moving in the world. It's what you use to walk around, talk, and even think.
Come to the top of the waterfall and you'll see the first example!
3- Look at the waterfall
Heather
You can sense the power of the water as it flows over the mountain, right? The water flows down this mountain and crashes to the lake below because of gravity. Before the water falls down the mountain, it has a lot of potential gravitational energy because it's a high altitude and we know that gravity will pull it to the ground.
When objects move, they generate kinetic energy; the potential gravitational energy is the amount of energy that will change to kinetic energy when the water falls.
Potential, gravitational and kinetic energy are only the beginning of the fun! Tap on the Monstrous Nightmare to look at the effects of the next type of energy.
4- Tap on the Monstrous Nightmare

This is the normal dragon fireball, right? It's made out of fire and heat as it leaves the dragon's mouth. It's composed of heat energy (or thermal energy) and light energy.
The hotter the item, the greater the thermal energy it has! As the fireball cools down, it loses its heat energy to the surrounding environment until the flame finally disappears.
But what about dragons that don't shoot fire? Let's take a look at one of the most ferocious dragons out there, the Skrill. Find him in the Lookout and tap on him!
5- Tap on the Skrill
Heather
The Skrill shoots electricity out of its mouth, instead of the normal dragon fireball! Electrical energy comes out when electricity creates motion, light or heat. The Skrill's shocking blast certainly qualifies for all of them!
Dragons are so uniquely different for each other. It's fascinating, isn't it? I've been working with Fishlegs to document the scientific differences between the dragon species, I hope you'll be able to help me with that too.
Now! Let's find the Thunderdrum and tap on him!
6- Tap on the Thunderdrum
Heather
The mighty Thunderdrum uses sonic blasts to cow its enemies. Sound energy occurs when things vibrate. When the Thunderdrum shoots its powerful sonic blast, it travels as high frequency waves.
This waves vibrate the air and cause things that the air touches to also vibrate! This sonic wave blast can literally knock a Viking over!
As much as I get annoyed at Snotlout, he is a valued member of out team. Please give him this snack. When he eats this snack, he'll gain chemical energy. He can't use chemical energy as it is, but remember that energy can change forms (Instead of being destroyed or created).
The chemical energy is stored as potential energy until his body needs to transform it into kinetic energy to walk, move, and go about his day.
Maybe the snack will stop him from complaining... but I doubt it.
7- Give the food to Snotlout
Snotlout
Oh. I was hoping for a home cooked meal... but this is nearly as good. Thanks to you, [your viking name], Heather revealed her true intentions. I won't forget this favor!
