Announcing Lab Content Updates!

Announcing Lab Content Updates! Featured Image

We are pleased to announce content enhancements to our digital science labs for the upcoming fall semester. Based on feedback from our instructors and students, we’ve improved our approach to creating and delivering science simulations. For the Fall 2015 term, 20 library labs have been significantly revised.



Please review the list of labs below carefully as they may affect your courses. If you currently assign one of the revised labs, the old version of the lab will no longer be available from your course on July 20th, 2015. This affects both the view of your section and within your gradebook.

You will be prompted to add the new version of your existing lab if you attempt to duplicate your section, and all new labs will be available when you set up a new section. If you are using a custom version of any of these labs, we recommend switching to the new, improved versions listed below. 


The content updates contain:

  • An increased focus on learning outcomes with learning objectives clearly identified in the description of the labs
  • An addition to the lab’s manual demonstrating real-life connection between what students will do in the lab and how the lab’s content applies outside the lab
  • A new organization for short answer assessment questions to read more like a lab report, with sections for Lab Results, Data Analysis, and Conclusions
  • Additional questions in both short answer and multiple choice assessment demonstrating critical thinking
  • Worked out solutions to mathematical short answer questions to make grading faster and easier
  • Lab and assessment revisions by a team of subject-matter experts who teach in the field


The following labs and their assessments have been reviewed and revised to ensure accuracy, ease of use, and the new features you see above. 


Chemical Reaction Types and Their Equations

Density: A Characteristic Property

Sample Lab

Stoichiometry of an Acid–Base Reaction

Biology and Microbiology

Acids, Bases, and pH Buffers


Basic Microscopy

Control of Bacterial Growth

Mitosis and Meiosis


Hooke’s Law

Newton’s Second Law


In addition to the changes above, the following labs have also undergone a title change.


Alcohol Content of Vodka by Dichromate Titration is now Oxidation–Reduction Titration

Chemical Kinetics of the Peroxodisulfate Reaction with Iodide is now Chemical Kinetics

Biology and Microbiology

Cultivation of Microorganisms is now Cultivation of Bacteria


The labs below include changes to procedures or instruments.


Conservation of Mass: Students use different instruments for data collection that give clearer, more consistent results.

Determination of Absolute Zero: The rates of temperature changes are slowed to allow for easier, more accurate data collection.

Volume of Air as a Function of Temperature: The rates of temperature changes are slowed to allow for easier, more accurate data collection.

Biology and Microbiology

Diffusion and Osmosis: The procedures have been altered to eliminate long student wait times associated with diffusion events. In addition, the dialysis tubing has been updated for new functionality and data collection.

Scientific Method: This lab has changed from investigating the eating habits of a cricket to a metabolism study of a model organism (mouse). In addition, the procedures and shelf materials have been altered to allow students to manipulate and measure variables they could not manipulate in the previous version of the lab.


Torque: The apparatus in this lab has been updated to include mass readings for the meterstick, which enables different and better data collection and analysis.


We are passionate about delivering the most accurate, realistic, and engaging science labs and assessments! We look forward to your continued feedback on our in-lab content.
