1$ is less then 10 000 satoshi (BTC), but even that is not easy to get for free. You can try on faucets, but it will not be instant and it will not be easy, especially if you are not trained to avoid all traps they have today.

I know you want to earn it, but I can send you that 1$ in BTC, and you can maybe do some small task for me, just send me PM with your BTC address
