I set a variable named $G2_HW_sci. This is the output with echo.
user@192 SS % echo $G2_HW_sci
~/Documents/trabalho/SS/G2/science/homework/student_work/
Then I tried to access the contents of this folder with ls but I am getting this error:
user@192 SS % ls $G2_HW_sci
ls: ~/Documents/trabalho/SS/G2/science/homework/: No such file or directory
user@192 SS % ls "$G2_HW_sci"
ls: ~/Documents/trabalho/SS/G2/science/homework/: No such file or directory
user@192 SS % ls "${G2_HW_sci}"
ls: ~/Documents/trabalho/SS/G2/science/homework/student_work/: No such file or directory
user@192 SS % ls $"G2_HW_sci"
ls: $G2_HW_sci: No such file or directory
Now, if I just use ls with the absolute path to the directory it works:
user@192 SS % ls ~/Documents/trabalho/SS/G2/science/homework/student_work

2B G2C_boris.jpg G2E_angeline_1.jpg
2C G2D_hellen_1.pdf other
G2C_jerry_1.jpeg G2D_leonidas_1.2.jpg
Another option that works is:
echo $G2_HW_sci | ls
I read some materials around here but they all seem to be using bash and by trying their solutions it didn't work for me.
I believe it may have something to do with the fact that I'm using zsh instead of bash.
What can I do to see the contents of the folder with the ls command?

You don't show how you assign the variable in the first place, but usually issues with
~in variables come from the way you quote (or don't quote) during assignment. To make it work you need to omit quotes when assigning~to a variable.
