Some of the things that we learned are: 1. Rust is bad for everything. Paint helps prevent rust. Salt can make cars rust, which is why in the winter time, the salt that is used on the highways needs to be washed off of our cars.
Galvanization helps protect objects from rusting. We are still wondering How long does it take for something to rust? Is every car affected by rust? Thanks but mean is it a car, wheelbarrow, etc.?

Tomorrow I have a 2 hour chemo treatment and I will definitely be on here!
I have been in the hospital for 2 months and found out about my cancer 1 week ago. I have had 3 treatments so far and will continue to have a treatment daily. The sad thing is that I'm alone most of the time. My family lives in Maine but I am at a hospital in Massachusetts. Do you have any wonders about cancer? Rust is metal's worst enemey. I have seen plenty of rusted cars, bridges, and other forgotten things with metal in it.
I have learned so very much today like that there is a material that does not rust for that reason. Also I have learned that air and water could make rust worse together than just by themselves. I have also learned you can paint over rust. I can't see how you can paint over rust without it growing back. Does it work geting rid of rust if a car is about to fall apart? I think tomorrow's wonder is about computers in general or the franchise of Apple.
Grace Sep 11, This video was kind of gross even though it's just rust. It looks like termites are eating your car aaaaaaaahhhhhhh!!!!!!!!!!!!
I can't wait to see tomorow's. I think it's the future touch screen: everything you can open the curtain from the wall, your table turns into the internet that would be cool.

He showed me today's wonder and I got so excited. You guys are the ones who encourage me to keep on fighting. Thank you. I think tomorrow's wonder will be about a new type of chemo for cancer fighters. Wow that video was mind blowing!!!!!!!!!!!

Rust is usually used to refer to a very common, reddish-brown compound called iron oxide Fe2O3. Iron oxide is formed when iron and oxygen react in the presence of water or moisture in the air.
I also learned from this web and wonder today that cars can rust a lot? Well I didn't know. And how many iPhones have been made and also maybe about Steve jobs and maybe a little video on him and how he discovered apple in his garage with two friends. Thanks wonderopolis!!!!!!!!!!!!!!!! Smith's Class Sep 11, Dear Wonderopolis, Thank you for the fabulous video of the car rusting. We can't wait! Turner Sep 11, Hello from Mrs. Turner's Fabulous Fifth Grade reading class!
We learned a lot about rust today! One of the coolest things was how rust is sort of like fire. We also think that is why people having their cars painted is so important. We wonder what are the main things that are affected by rust besides cars. Our predictions for tomorrow's wonder is that it will be about computers! Ouverson's Fourth Grade C Sep 11, Sincerely, Mrs. Ouverson's Fourth Grade Class.
Foster's Class Sep 11, How long will it take for a car to rust if it's left unprotected?

We also learned that rust can turn really brown. We are wondering whether tomorrow's technological wonder is about something that will be helpful or harmful. We are wondering whether it could be: flying cars, touch-screen technology, or a robot like Rosie from The Jetsons.
Wonder Friend "M" Sep 11, Ramsdell's Class Sep 11, We loved watching the car corrode! We think tomorrow's wonder may be about robots or jet packs.
