The GCISD science department uses an online textbook called STEMSCOPES.  STEMscopes provides students access to lessons and activities in class, but also provides them resources to access at home.  These can be found in the "Learning Resources" section of STEMscopes under "STEMscopedia".  Students will be taught how to use this resource in each science class.  
 It can be accessed through Classlink.
