Teacher worksheets for your science classes of all grade levels. Whether you are teaching biology, hydrology, botany, or chemistry, or just studying the lives and work of famous scientists in general, each of the following sets of worksheets contains multiple individual reading passages for your students. Two separate answer sheets are associated with each passage. One is a multiple choice worksheet and the other is a short-answer worksheet. Instructors may choose to use either or both question sheets (answer keys are provided for all worksheets). You will find a nice helping of reading in the content area sheets here too.

The worksheets span a wide array of topics. The interesting thing is that we always find a way to cover elementary, middle school, and high school topics and leveled work.
