About the Biology Keystone Exam in 有料盒子

Keystone Biology Item Sampler

The Biology Keystone Exam is Pennsylvania’s end of course assessment for Biology.  It consists of two test modules that each take approximately 1.5 hours to complete.  The exam contains multiple choice questions and open-ended responses that are designed to assess student comprehension of Biology.  For a student to perform at an advanced level they must be able to do the following:  

• Evaluate the application of scientific reasoning, inventions, tools, and new technologies in the study of biology.   
• Apply the scientific concepts of hypothesis, inference, law, theory, principle, fact, and observation. 
• Analyze structural and functional similarities and differences between prokaryotes and eukaryotes. 
• Evaluate relationships between structures and functions at various levels of biological organization (cell, tissue, organ, organism). 
• Analyze the unique properties of water and explain how they support life on Earth. 
• Analyze and predict how enzymes can regulate biochemical reactions within a cell. 
• Analyze cell structures (mitochondria and chloroplasts) and processes (cellular respiration and photosynthesis) that transform energy in living systems. 
• Analyze and predict how cell structures transport material into, out of, and within a cell. 
• Analyze how organisms use feedback and response mechanisms to maintain homeostasis. 
• Compare and analyze the three stages (interphase, mitosis, and cytokinesis) and the outcomes of the cell cycle. 
• Analyze and predict how genetic information is inherited, altered, and expressed. 
• Analyze the processes (transcription and translation) associated with protein synthesis.
• Predict the impacts of genetic engineering on medicine, forensics, and agriculture. 
• Evaluate the mechanisms and sources of evidence related to the theory of evolution. 
• Compare ecological levels of organization in the biosphere (individual, population, community, ecosystem). 
• Analyze interactions and relationships in an ecosystem as they relate to energy flow (food webs), biotic components, biogeochemical cycles (water, carbon and nitrogen cycles), and limiting factors. 
• Predict changes in an ecosystem in response to natural and human disturbances.  

Taking the Biology Keystone Exam in 有料盒子

Students who are currently enrolled in Biology will take the exam in class. 

Students who need to take the test and are not enrolled in Biology will take the exam in the semester of their current year science course.  For instance, if a student has chemistry in the spring semester he/she will take the test in the spring. 

The testing window is in January for the fall semester and May for the spring. 

Preparing for the Biology Keystone Exam in 有料盒子

Students currently enrolled in Biology will naturally prepare for the exam as they progress through the course.  The 有料盒子 science curriculum is fully aligned with the Pennsylvania state standards and therefore the content of the exam. 

Students not enrolled in Biology can prepare for the exam using the following resources:
