i had to do some volunteer work in 8th grade. i chose to do it at an animal shelter. it was so easy, i only needed 10 hours and all i had to do was show attention to the animals that might not get it.. aka the reject animals hahah

it was still cool tho, i just took them in this room and played catch and played with them and stuff. easy stuff, i reccomend it if you need to get some hours in.

----EDIT----
just saw that you have to be 16... well i dunno lol i went with my mom so i guess my age didnt matter.
