Science Buddies: "Ask an Expert"

Hello,
I am building a hydrogen generator for my middle school science fair and I can't think of any good questions or hypothesizes
for it. Any ideas? I need this answered by Monday next week because this is when we turn in our experimental design.

Hey there.

What an ambitious project! Congrats up front on picking something so interesting and cool. So, unfortunately I am not going to be able to help a lot with this since I know nothing about your project details wise (perhaps you are doing this project? https://www.sciencebuddies.org/science- ... l#summary. )

Just remember that when you are picking a hypothesis that If/Then questions are the key. I would try to hone in on why you made the choice to build the generator. Were you looking at hydrogen generators as a more realistic alternative than other generators energy output wise? Cost wise? Clean energy wise?

Just think it over a bit, and let your imagination go wild.

Here is a bit more information on hypothesis in general https://www.sciencebuddies.org/science- ... esis.shtml

Good luck, and have a great time.

Hi heineraa,
It seems as if you are doing a demonstration instead of an experiment.
From what you have told us, you are making a hydrogen battery, but there are no variables you are changing.
Are you seeing if certain "ingredients" will make the hydrogen battery more powerful?
If a homemade or store-bought battery is more powerful?

Just know that a hypothesis is what YOU think. There's no going wrong with a hypothesis.
Remember that you should always include reasoning behind your hypothesis.
For example, a basic format for a good hypothesis is:
I think that _______, BECAUSE _________. State what you think and back it up with reasoning.
This reasoning should come through a bit of background research.

Most of all, have some fun! Don't stress too much.
