Science Buddies: "Ask an Expert"

please what do you think about these idea : how fast does alka seltzer tablet make gas
does co2 cause increase in atmospheric temperature?
how does acid rain affect the flora environment?
my teacher already rejected the bottom two and i don't know what to do. I;m in tenth grade and i need an appropriate topic

If your teacher already rejected two of the questions you've listed, it sounds like you may need to search for a new topic. You might try the Topic Selection Wizard at Science Buddies. It can help you locate projects of interest. When viewing projects, you can also look at the "Make it your own" tab to find suggestions for variations, as well.

There are several projects at Science Buddies that deal with Alka-Seltzer tablets, but they are at the intermediate level, which will not work for your grade level. (https://www.sciencebuddies.org/search?v ... ka-seltzer)

I would suggest you try the Wizard.

You may also want to browse projects. These projects, for example, are projects that deal with chemical reactions and are more advanced: https://www.sciencebuddies.org/search?v ... +reactions
