A Low-Prep Work, Energy & Power Lab Students Actually Remember
One of my biggest issues with physics labs is having to leave the classroom to complete them. If I have to leave the room for any reason other than finding open space or a balcony to yeet things off, I'm annoyed. Instant inconvenience.
I refuse to hike all the way to the football field with 30+ students just to do a Work, Energy, and Power lab. Who has time for that? Nope. Not happening.
I did so many Google searches for a high school Work, Energy, and Power lab that didn't require stairs, bleachers, or special equipment and guess what...they basically don't exist.
So I improvised.
I created a low-prep physics lab that covers work, kinetic energy, the Work-Kinetic Energy Theorem, and power while getting students moving, collecting their own data, making calculations, and connecting concepts...without a staircase or bleacher in sight.
It's quickly become one of my favorite physics labs to teach.
If you've ever searched for an engaging Work and Energy lab that doesn't require hauling students across campus or ordering expensive equipment, you're not alone. This classroom-tested activity uses simple materials you already have and gets students actively applying physics instead of just watching someone else do it.
Don't feel like reinventing the wheel?
I've already created this Work, Energy, & Power Lab, and I'd love to share it with you. Grab it free through The Smith List, or keep reading for classroom tips you can use no matter what lab you teach.
Three Ways to Make Any Work & Energy Lab More Engaging
Whether you use my lab or create your own, here are three things that make a huge difference.
1. Make Students the Variable
Instead of rolling a cart down a ramp for the millionth time, let students become the experiment.
When students collect data about their own motion, they become invested because the results belong to them.
2. Compare Different Types of Motion
Rather than collecting one set of data, have students compare different movements like walking, fast walking, and skipping.
Students naturally begin noticing patterns before you even ask the discussion questions.
3. End With a CER Instead of a Formal Lab Report
Formal lab reports often become an exercise in formatting instead of scientific thinking.
A short Claim, Evidence, and Reasoning (CER) conclusion requires students to actually use their data to support a scientific claim.
Students Become the Lab Equipment
One of the reasons students enjoy this activity so much is that they become the experiment.
Instead of watching an object move or rolling a ball down a ramp for the millionth time, students collect data about their own motion.
It's kind of like play...but with physics.
During this investigation students:
Measure distance and time
Calculate velocity
Determine kinetic energy
Apply the Work-Kinetic Energy Theorem
Calculate power output
Analyze patterns in their data
Students compare several types of motion, including:
Walking
Fast (power) walking...think mall walkers
Skipping
As students move faster, collect data, and compare results, they naturally begin to see how work, energy, and power are connected.
Because the data belongs to them, they're far more invested in the outcome.
Honestly, it turns into a bit of a competition.
Reinforcing Multiple Physics Concepts
One of my favorite things about this lab is that it naturally ties together several concepts students often learn separately.
Instead of simply calculating answers and moving on, students explain:
How velocity affects kinetic energy
How work relates to changes in energy
Why two activities can involve similar amounts of work but very different amounts of power
How everyday human motion can be analyzed using physics principles
Students begin connecting ideas instead of memorizing equations.
Don't Skip the Discussion
A lot of times, this is where the learning really happens.
After students finish their calculations, resist the urge to simply read through the answer key and ask if anyone has questions. Instead, let students defend their thinking using their own data.
A few discussion strategies that work really well are:
Think-Pair-Share
Round Robin
Small-group whiteboard discussions
Explore 4 using the investigation question
You'll uncover and correct misconceptions that never show up during the calculations alone.
One of my favorite parts of this lab is listening to groups argue (respectfully!) about whose evidence best supports the investigation question. Those are some good conversations.
If class discussions are something you struggle with, don't feel like you have to reinvent those either. I use a collection of collaborative discussion structures to get every student talking, and I've included them in the free Collaborative Sharing Toolkit inside The Smith List. It's one of those resources I find myself pulling out over and over again throughout the year.
Teacher Tip
Before class, use painter's tape to mark the walking distance on your classroom floor or hallway. Students can immediately begin collecting data instead of asking, "Where do we start?"
It's a tiny thing that saves several minutes every class period.
Built-In Data Analysis and CER Writing
Many labs stop after students finish the calculations, or they require students to write a formal lab report that's honestly beyond what's necessary for many high school physics courses.
This one does neither.
Students analyze their own data, answer higher-level questions, and complete a Claim, Evidence, and Reasoning (CER) graphic organizer.
In my humblest opinion, CERs are one of the best ways to practice scientific writing.
Students intentionally comb through their data, identify evidence, and build an argument supported by physics instead of simply filling in blanks.
This moves students beyond memorization and helps them begin thinking like physicists.
Why I Love Low-Prep Physics Labs
Let's be honest...who doesn't love a low-prep lab?
It's funny how often my simplest labs become the ones students remember most.
The labs requiring the least amount of preparation often make the biggest impact.
This investigation only requires:
A meter stick or measuring tape
A stopwatch
A calculator
Open classroom space
That's it.
No expensive equipment.
No football stadium.
No special facilities.
No last-minute Amazon order.
(My husband definitely appreciates that last one.)
The best labs don't require expensive equipment.
They require curious students and thoughtful questions.
Perfect For
This activity works well for:
High school Physics
Honors Physics
AP Physics 1 introductions or review
Work, Energy, and Power units
Testing schedules
Teachers working with limited supplies
Whether you're introducing the unit or reviewing before an assessment, students leave with a much stronger understanding of how work, energy, and power apply to the real world.
Frequently Asked Questions
Can this lab be done without stairs or bleachers?
Absolutely. That's exactly why I created it.
Is it appropriate for AP Physics 1?
Yes. It works well as an introductory investigation, reinforcement activity, or review before assessments.
What materials do I need?
Just a measuring tape, stopwatch, calculator, and open classroom space.
How long does it take?
Most classes complete the investigation, calculations, discussion, and CER in a single class period.
