Biology

Break down your thesis into concepts. Develop a list of synonyms.

EXAMPLE: homeschooling AND socialization

Other terms for socialization could be interaction, acculturation, "social behavior" or "social development".
Combining different terms gives you different terms.

Clearly define your thesis statement. Trouble spots to look out for:

Too Broad - EXAMPLE: homelessness

• Solution: add another concept to your topic which will narrow your thesis and make it more focused.
  EXAMPLE: homeless and veteran

Too Narrow - EXAMPLE: homeschooling AND socialization AND "family income"

[NOTE: to search a phrase use quotes]

• Solution: Remove one secondary concept from your thesis.
  EXAMPLE: homeschooling AND socialization AND "family income"
