For students wanting to use Google Classroom at home, here are the instructions:
Go to www.google.com.
Click on the sign in button.
Log in with your student id# with the "email" ending @stu.sandi.net (example: [email protected]).
Enter your password if asked (the same one you use to log in to your computer at school). When logging in at home the login procedure might be a little different than at school.
After you are logged in to Google, click the 9 squares button and pick Classroom.
Click the + sign and join if you are joining a class or were given a join code. If you are not joining a class, then click on the class title.
For MatterMasters Science Club, enter the code: ahk1ux0 (the last digit is a zero).
