Sure can. No reason why not.
The biggest reason is that it is illegal (in most of the U.S. anyway)
Depends on the reason. If a student is homeschooled the teacher is required by the school district to go to the child's home, but if the reason is a social reason a teacher should not visit the child. Some school districts also require teachers to pay home visit at the start of the school year, but this is school business. Anything beyond school business is not proper unless the teacher is friends with the parents.

Biochemistry an nutritional science is used in a school cafeteria to assure that we are getting the proper micro and macronutrients as students.
