UL Xplorlabs is making the world a safer place through science. For example, their Fire Forensics: Claims and Evidence unit is a safe way to educate middle school students about fire. This unit teaches about fire while meeting Next Generation Science Standards. Generally speaking, this free interactive STEM lab takes 2-4 days to complete and includes extension science experiments that you could add to the unit.
Fire Forensics: A Free STEM Module for Middle School Science
The Fire Forensics: Claims and Evidence module is designed to
“provide students with the understanding of fire, fire dynamics, and fire behavior so that they can read a fire scene and build a claim for the fire’s location of origin and cause.”
As it has been noted, UL (Underwriters Laboratories), the creator of Xplorlabs, is a global safety science company. Consequently, they work to foster safe living and working environments for people. (Not only are the UL Listed safety marks for many of the appliances in your house from this company, but they also are creating free science-based modules that promote safety like this one.)
Each learning module is designed to connect classrooms to real-world science and engineering. After testing it, I found this middle school science unit to be full of interactive video, online experiences, classroom activities, and challenges. For this reason, I think kids will love the real-world interactivity of this unit.
How to Get Started With Fire Forensics
As I demonstrate in the Unboxing video (above), before clicking the “Getting Started” button in the Fire Forensics Module, download the Teacher Guide and take a look at the science experiments that go along with the module. This Guide includes:
- Fire Lab Safety Instructions
- Safety Data Sheets for each activity including PPEs (personal protective equipment)
- Supplies and summaries of labs, including outcomes and assessment tips
You can have students watch the video module on their iPads, Chromebooks, or other devices, or you can project it on your board and go through it as a class. After you download the Teacher Guide, I recommend that you go through the entire unit on your own to prepare.
What science standards are taught in this unit?
- MS-PS1: Matter and Its Interactions (MS-PS1-2 and MS-PS1-3)
- MS-PS3: Energy (MS-PS3-5)
- Common Core State Standards (See more on the Fire Forensics Site)
- RST.6-8.1, RST.6-8.3, RST.6-8.7
- WHST.6-8.1, WHST.6-8.7
2-4 class periods minimum for the online activities (but additional extension investigations will take more time).
The Stages of the Lab
1 – Fire Investigators in Training
Students start by becoming “fire investigators in training.” They prepare to identify and analyze fire scene evidence.
2 – Examination of Evidence
Students check out two UL Fire Lab burns of full-sized structures that were conducted under different experimental conditions. After the experiment, they’re able to examine different burns side by side while changing only one variable — ventilation. Additionally, UL fire scientists share what they can observe in each burn. Students will also use charts to learn how to analyze the burns.
3 – Learning From an Expert
Students will walk through a fire scene with a burn investigator. They’ll learn to build a claim as they understand the cause of a fire and where it started. At this stage, they’ll understand the scientific method for analyzing the clues. Then students will prepare to create their own investigation.
4 – Solo Investigation
Students are now ready for their own investigation. Using the online interactive experience, they’ll work their way through the burned structure seeking the evidence to determine the fire’s cause and place of origin. Students are building their claim for how the fire started as they seek four or more pieces of evidence to enter into the notebook.
5 – Submit Your Claim
Finally, students submit a claim from their independent investigation of what they think happened in the kitchen burn.
6 – Compare Results
After students complete the experience, research engineer Dan Madrzykowski will share the fire’s origin and cause so that students can see where they were correct. They can also compare their own claims with other students’ claims.
This unit includes additional extension experiments:
- The Fire Triangle: Understanding oxygen, fuel, and heat — the needs of fire.
- Heat Transfer and Ignition: Students learn how different materials ignite and burn.
- Fire Lab Data Analysis: Students learn about the impact of ventilation on a fire.
There are additional extension activities associated with the other module available via UL Xplorlabs, Portable Electrical Power, which focuses on lithium-ion batteries and “explores how batteries convert energy, introduces the phenomenon of thermal runaway and inspires students to think like a scientist to identify essential construction and performance requirements that address the inherent risks a product could present.
- The Bologna Test: Students observe the energy from button cell batteries and can understand the dangers from child ingestions with this experiment.
- Tensile Test and Durability: Students learn about the types of testing that safety engineers put materials through.
- Thermal Test: Students will learn some typical ways that batteries can experience “thermal runaway.” Students assume different roles as they conduct this experiment.

In conclusion, UL Xplorlabs has created a fantastic science module for teachers on a key topic for middle school science. I also like the fact that you can mention the importance of fire safety and talk about the UL labels that we all have on our appliances as well. This can be a challenging topic to teach and discuss because of the dangerous nature of fire. I think Fire Forensics: Claims and Evidence is a must-use module for middle school science teachers everywhere to use. Enjoy!
