Run it in one period.

No login | No car needed | Projector or phones | Print in one click | Answer keys built in

Each pack is a complete lesson. It has objectives, a short story from our build, a diagram, a simulation, a worked example, marked questions, a printable worksheet and a separate answer key. This page shows where each pack fits and how we would run it.

Three steps, no set-up.

Every pack has the same shape, so once you have run one you can run them all. The timings in each lesson plan add up to the period length on the pack.

01

Open and project

Open the pack on the classroom screen. The sections are numbered 01 to 07 in the order we would teach them. Put the simulation on the board and let students call out what to change before you change it.

02

Print the worksheet

Press Print PDF on any pack. Only the cream worksheet prints. It is one or two A4 pages with write-on lines, a formula bank and marks in brackets. Choose Save as PDF in the print dialog if you want to set it online.

03

Mark with the key

Switch on Teacher mode below or on any pack. Answers appear under each question on screen, and a green answer-key sheet is added when you print. Turn it off before you put the pack back on the projector.

Teacher mode

Teacher mode is off. Answers are hidden.

Where each pack fits.

Grade bands are a guide. Chapter names are from the NCERT and Cambridge IGCSE syllabi. The same ideas map onto ICSE, IB and most national curricula.

A good order for a five-lesson unit is 02, 05, 03, 01, then 07. Pack 04 works as a numeracy starter anywhere. Pack 06 stands on its own in chemistry.

What we would tell a colleague.

Ask for a prediction before you press run

Every simulator has a setting students think matters more than it does (the bearings on the race bench, or area against Cd in the drag pack) and one they underestimate (mass, or the foam thickness at the stop). Get the class to predict first, then run it. The gap between the guess and the result is where the learning happens.

Three lines every time

Every calculation in the packs is marked in three lines: the formula, the numbers put in, and the answer with a unit. If students keep to that, unit mistakes show themselves. NM-LAB-04 exists to build the habit.

The numbers are realistic, not certified

Race times, drag coefficients and bearing torques are the right size for a STEM Racing car, but they are not official test data. Where a pack quotes a real Nightmare measurement, it says so. Students should not cite the packs as a data source in a project.

Partners appear where the part is theirs

Boca Bearings is named in NM-LAB-01 because the hybrid ceramic bearings on our car are theirs. SimScale is named in NM-LAB-03 because our Cd values come from their CFD. There is no advertising on the worksheets, only credit where it is due.

Safety in NM-LAB-06

A charged CO₂ cartridge is a pressurised container. Never open, heat or puncture one in class. A fired, empty cartridge is safe to pass round and makes a great starter.

Questions we get asked.

Do I need a STEM Racing car or a track?

No. Every pack runs from the web page and the printed sheet. Where a real object helps, like a wheel for the spin-down test or a fired cartridge, the pack says so, and it still works without it.

Can I use these outside India?

Yes. The physics, chemistry and maths are the same everywhere. The curriculum map gives NCERT and Cambridge IGCSE chapters, and the same ideas sit in IB, ICSE and most national syllabi.

How do I set a pack for homework?

Each pack has a QR code and a copy-link button in the sidebar. Students open the same page on a phone, and the simulations work with touch. Teacher mode is off by default, so the answers stay hidden.

Why does printing only give me the worksheet?

That is on purpose. Printing drops the navigation, the simulation and the sidebar so you get a clean one- or two-page sheet. With teacher mode on, the answer key prints as an extra page.

Is the download counter real?

It counts prints and saves on the device you are using. We show it so you can see how it works. Our season totals come from the site analytics, not from this number.

Can I edit a pack?

The packs are free to print and use in class with credit to Team Nightmare. If you would like an edited or translated version, write to us through the main site and we will send you the files.

Who wrote these?

Team Nightmare, a STEM Racing team competing at the World Finals. Every pack starts from a decision we actually made on our car this season.
