About This Simulation
Become an environmental investigator and solve a massive fish kill mystery. First, learn about the different trophic levels of the ecosystem. You will then perform a fish necropsy and use a spectrophotometer to analyze oxygen levels in the water.
Learning Objectives
- Understand the basic concepts of sample collection
- Perform fish necropsy and learn the information you can get from this kind of approach
- Learn the concepts of trophic levels, trophic pyramids and the energy flow in an ecosystem
- Learn the difference between heterotroph and autotroph organisms
- Analyze the level of dissolved oxygen level in your water sample using a spectrophotometer
- Learn the concepts of a calibration curve, linear regression and extrapolation

Learn More About This Simulation
Can you get to the bottom of a mysterious massive fish-killing? In this simulation, you will be an environmental investigator to solve this fish kill mystery. You will learn about oxygen levels in water and its impact on fish, and energy flow in an aquatic food web. You will perform a fish necropsy and analyze the level of dissolved oxygen by gathering data from fish and water samples to help test your hypothesis.
Analyze the oxygen levels in water
You will first have to collect water samples from the bay where the fish were found. Using a spectrophotometer, you will compare these samples to known values to investigate whether low oxygen in the lake could have caused the massive fish death. Do the fish exhibit symptoms that correlate with low oxygen levels?
Dissection of a fish
Complete a fish necropsy without getting your hands dirty! Dive into the dissection to examine how the fish’s physiological responses can shed some light on the cause behind the fish death. In this simulation, you can skip the long waiting times that would normally occur in real-life necropsies and immediately get your hands on the results to continue your investigation.
Solve the mystery
In this fish-killing investigation, you will have to gather several pieces of information that you will need to figure out what caused the massive fish death. Will you be able to put the pieces together to solve the mystery?

North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."
