CSI – Crime Scene Investigation
In the Crime Scene Investigation lab, you will be thrown right into a crime scene, where a murder has taken place. To investigate the crime scene, your first task is to collect blood samples in hopes that the murderer has left traces of DNA.
Perform a DNA analysis
After sampling, you will get accesses to a virtual lab to perform a DNA analysis. In the lab, a PCR kit, purified DNA from the crime scene, and a full lab bench set up are available. It is now up to you to mix the correct reagents and perform PCR in the lab PCR machine.
See the DNA structure and replication up close
A 3D animation will show the Polymerase Chain Reaction at the molecular level, illustrating DNA structure and replication. Quiz questions will be asked throughout the experimental process, as well as at specific steps of the PCR reaction itself. With the media player function, you will be able to see the animation several times, pause it, or revisit it at a later time for exam preparation.
Identify the murderer
In the Crime Scene Investigation lab, you will run a gel on your collected sample and other already prepared samples from suspects, and then compare the patterns that emerged on the gel.
Will you be able to identify the murderer?
Techniques In Lab
- Gel electrophoresis
- DNA profiling
In the Eutrophication lab, you take the role as an environmental investigator whose mission is to solve a massive fish kill mystery.
Help the suffering fish
In the Marine Biology lab, you discovered that the fish were dying of suffocation, and now you want to know more about what caused the low dissolved oxygen levels. In the Eutrophication lab, you will use microscopy to analyze the biological matter in the water and spectrophotometry to study dissolved nitrogen levels. This will give you the data you need to conclude your investigation.
Analyze water samples
In the Marine Biology Lab you discovered that the low oxygen in the water was causing the fish to suffocate. Looking for more data, you will now analyze the water sample using the microscope. In this way you can study the biological matter in the water to find out if the algae could have something to do with the low oxygen levels.
Determine the source of the algal bloom
In the Eutrophocation lab, you will learn about the nitrogen cycle and how human activity can influence it. You will analyze nitrogen content in the water sample using spectrophotometry. An interactive map will help you determine the source of the excessive nitrogen run-off that caused the harmful algal bloom.
Will you be able to solve the fish kill mystery?
At the end of this simulation, you will be able to…
- Understand the nitrogen cycle and its importance for living beings
- Understand the concept of eutrophication and harmful algal bloom, and the impact that it has on the ecosystem
- Analyze dissolved nitrogen levels in the water sample
- Understand the importance of sampling from different locations to get representative data
Techniques In Lab
- Fish necropsy/dissection
High Quality Labs
Labster collaborates with top universities, including MIT, Harvard, Imperial College and ETH Zürich. Our labs are specifically designed to support students at any level.
Quiz questions and Assessment
Students only progress in Labster when they understand the theory, and each students skills are assessed and reported in a teacher’s dashboard.
Our labs are designed to match the learning goals of science courses at universities and colleges. Students can experiment and make mistakes, and are engaged by investigate cancer drugs and even solving a murder mystery.
Our interactive 3D animations show students what is happening at the molecular level when performing experiments. This is often a “black box” for the students when performing real experiments.
How it works
A million dollar lab in your browser
You can now perform advanced experiments to achieve core science learning outcomes. Theory and practise are connected in a novel way, and all you need is a computer/laptop and a browser!
Our simulations even run on older laptops and computers, and you will be able to play our simulations without having to install any browser plugins.
