Help: How to make my 7 year kid video to get many "likes" on her school youtube channel?

[joooo]

My daughter school gave her homework to sing in front of camera, and they put it on their youtube channel.
How to get many "likes" on my daughter video on other youtube-channel ? I really want her to pass the test and make her happy.

This is her youtube video :

I don't need people to subscribe, just 3 seconds of their time to "like" the video.
Please advise, thank you.
