We usually have blue landing fires so the dragons know where to land. What makes blue fire? I have no idea. Can you find out for me?
Heather should be able to help you figure it out. You should talk to her by her laboratory.
1 - Meet Heather by the Lab
Heather
It's really great to meet you. Did you know blue flames are really, really hot? I think there are other ways to make our flames blue too. Let's find out together!
We can use the scientific method, just like Hiccup! We'll use 5 steps of the scientific method: problem, research, hypothesis, procedure, and result.
The problem is the scientific question that will be tested in the experiment.
Quiz 1
Heather
We'll need to figure out some chemical reactions to change fire color! Our next task is to do a little research. Research is the step in the scientific method where you find out information that's already known about the problem you're testing.
You can research things by talking to others about their experiences with the items we need to test. A list of the materials we need for our experiment will be found in your Quest Log. You'll need to get these rocks from Astrid, Fishlegs and Snotlout here at the school.
2 - Collect tolbachite from Fishlegs
Fishlegs
Fishlegs Ingerman at your service. I was so excited when Meatlug and I found this tolbachite by the volcano! It was kind of scary with steam and gas everywhere. You can have my last piece!
3 - Collect rock salt from Astrid
Astrid
I found this rock salt when the lake dried up last year. It must have formed when the water evaporated. Why don't you use it for your experiment?
4 Collect sylvite from Snotlout
Snotlout
'Sup? I'm Snotlout, master of awesome. Hookfang and I found this sylvite at our secret training island! Cool, huh? It's really rare but I'll let you have it for your experiment. Just remember, you couldn't have done this without me!
Heather
Well done. Come see me at The Lab and we'll have some fun!
5 - Take your findings to Heather at The Lab
Heather
Now that we have done our research and collected facts about our testing materials, we need to form our hypothesis. The hypothesis is an educated guess about how you think your experiment will turn out.
Quiz 2
Heather
The procedure phase is where we test out our hypothesis to see if it's true or false. Let's choose the hypothesis that we'll test in our experiment.
Quiz 3
Heather
Interesting choice! Okay, let's get on with the experiment. Toothless is really excited to help you out.
Let's go inside The Lab.
8 - Burn the rock salt
(Experiment tutorial)
Heather
Great work! You proved your hypothesis to be true/false. Your results are the outcome of the experiment. You'll use them to analyze, or figure out, the conclusion at the end of each experiment.
9 - Talk to Heather to take the final test
Quiz 4
Heather
That was really fun! Come to me any time you want to do an experiment. You should go back to Bucket and let him know what you found.
10 - Talk to Bucket
Bucket
I understand! Now I need to find some tolbachite to relight the blue fires. Thanks, [Your Viking's Name]! You've been a great help. I would give you the very bucket on my head, but I need it.
