  • Understanding chemistry equipment like balances, stirrers and burners

Experienced instructors guide you through each video lesson, and self-assessment quizzes are provided to gauge your understanding. Lesson summaries and links to key terms can assist you in preparing for the Praxis II Biology and General Science test.

Praxis Biology and General Science: Science Safety Objectives

The Praxis II Biology and General Science test attempts to assess your readiness to teach biology and/or general science at the secondary school level. Laboratory safety methods are contained in the chemistry section of the test, which accounts for about 10% of the total exam. The quizzes included with each lesson contain questions that resemble the actual problems you'll see on the Praxis II test.

The test consists of 120 multiple-choice questions, which must be finished in two hours. The problems on the Praxis II exam will test your recognition of science terms, principles and laws. You'll also need to apply these concepts to situational problems. Other questions involve hypothetical laboratory and field experiences.
