During your visit, look for clues as to whether science is valued. If so, ask the librarian if the children are encouraged to read them. Ask questions about the science program at parent-teacher conferences or PTA meetings. Or set up an appointment with the school principal. This provides you with information about the science program and lets educators know you think science is important.
Educators are more apt to teach subjects they know parents are interested in.
If the science program is inadequate, talk with your child's teacher or meet with the principal. If that brings no results, write to or meet with school board members. You might get better results if you organize with other parents who have similar concerns. Volunteer your services to improve the science programs.
