Science fair?

I was wondering if our lovely community could give me some good ideas to choose from for my science fair project this year as I don't have many ideas of what to do cause I'be been entering for 5 years and also done projects for my own benefit in my future so if you guys could give me good ideas of what to do it would be great!

Thank you for your kindness for helping me choose

See how many times it takes for every species of dog to die after being hit over the head with cement.

 

You can't do that where I live cause it's "animal cruelty" and I don't wanna go to jail but thanks mix for the idea

 

Your welcome b

 

Not unless u look it up

 

Honestly don't know, either way, good luck at your science fair!

 

OOH! New Idea , Make a experiment where you feed turtles weed and see how long it takes them to think they are flying.

 

Nice idea but I would get into trouble for possession of weed in school

 

Well what grade are you in?

 

Year 11

 

I had an actual good idea but it was just too expensive

 

Hmmm, Maybe go for something with chemicals then. In your older years the judges really got turned on for chemical bonds and reactions. Easy ones are found and are associated with Iodine or Hydrogen reactions.

 

I've made home made solar cells and I've done contact powder(when it touched with certain pressure it explodes)

 

How do they work .-.

 

In my case I made a TiO2 solar cell(DSSC) and I basicly used indium tin oxide, Titanium dioxide, white vinegar and triodide(iodide electrolyte)

 

I have a video on making it I can show you the process on how I made it and I did it in about 4-5 hours

 

You could test which kind of gun and which kind of bullets are the best for shooting up a school... I mean for the army!

 

You could test how home made fire tornadoes work, my teacher said i couldn't do it last year because she didn't trust me with fire and it was science. But she thought a poll on what is shoe brand was better was. And this isn't a joke idea i really wanted to test how they worked.

 

Guns are illegal where I live. You need a license+papers that take up to 1 month to get (license is about 200€)

 

I've done it in class 3 years ago in chemistry class and I've also done one with liquid hydrogen and dry ice thanks for the ideas tho <3
Please keep letting me know with more!
