Cells CER Bundle


The claim, evidence, and reasoning (CER) model is a method for teaching students to think and write scientifically. By going beyond simple one-word responses, this Cells CER model encourages students to engage in a more comprehensive and analytical approach.


Using these resources, your students will learn to make a claim, justify their answer with data, and connect the data with scientific reasoning. This process helps students understand the importance of evidence-based arguments and cultivates their scientific literacy.


The importance of the CER model is especially evident when aligned with the Next Generation Science Standards (NGSS). Virtually every unit of study incorporates standards that lend themselves well to the CER model. Integrating the CER model into the curriculum provides students with a systematic framework to approach scientific investigations and inquiries.


A perfect addition to any Cells Unit, this resource offers a comprehensive tool to introduce and practice the CER model with your students. It equips educators with all the necessary materials and guidelines to facilitate the implementation of the CER model effectively.


To cater to the diverse needs of students, this resource includes four differentiated versions of each question prompt. The differentiated versions provide varying levels of scaffolding, allowing educators to meet students at their individual skill levels. The versions range from a basic question with no scaffolding to questions with the claim, evidence, or reasoning partially completed, challenging students to fill in the missing components.


Additionally, an error analysis activity is included, which prompts students to critically evaluate a CER response written by someone else. This activity helps students develop their analytical skills by identifying and discussing potential errors or areas for improvement.


Rubrics and handy reminders for students regarding what to do for each part of the CER are included in both the print and digital versions.
