The Science Fair Event school mod allows your child and teen Sims to attend the science fair and win a trophy. This simple yet fun afterschool activity is a great way to fill up your gameplay with interesting storytelling. Your Sim will work on their desired project before submitting it to score first, second, or third prize. If you win, you get a buff and a trophy to showcase your accomplishments. Note that you need the Parenthood pack for this mod to work correctly.
Follow these steps to install Science Fair Event on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.

Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
