Velocity Arena · Make Your Equation Poster
Thursday you teach a visitor standing at your station. This poster is what you teach from. Build it today.
Every number on this poster already exists. It is on your Distance Lab sheet. You are not solving anything new. You are copying your work onto something a stranger can read from six feet away.
If your Distance Lab sheet is missing the equation in Step 7, finish that first. Nothing else on this poster works without it.
Do these four steps in this exact order. The QR code will not work if you skip ahead.
Your poster is empty right now and that is fine. The link works from the moment the file exists and it does not change while you build.
A Canva QR code is frozen the second you make it. You cannot point it somewhere else later. Get the real link now, build the code from it, then design the poster.
Black code, white background. No colors, no photo behind it.
Leave empty space all the way around it. Nothing touching the edges.
Test it before you print. Point a phone camera at the screen. If it does not open your poster in about two seconds, delete the code and build it again from a fresh copied link.
All seven have to be there. The numbers in the map match the numbers in the table.
A map, not a rule. Move things around if yours reads better.
| What goes on the poster | Where you copy it from |
|---|---|
| 1Team name | Big, across the top. Readable from across the room. |
| 2Your names | Every person on the team. First name and last initial. |
| 3Photo | Your team with your bot. Upload it from your device. |
| 4Your stats | Speed, Power, Endurance, Turning. Write the four numbers and check they add to 20. |
| 5Your equation | the Distance Lab, Step 7. Copy it exactly. |
| 6Your graph | the Distance Lab, Step 4, with the two dots you added in Step 9. All five. |
| 7QR code | The one you just built in Section 2. |
Copy your two numbers off Distance Lab Step 7 and write them here first, before you type anything into Canva.
Your start-up cost is negative. Distance Lab Step 6 told you to keep the minus sign, and it still belongs there.
Do not write + −7. That looks broken. Write it as a subtraction instead:
distance = 22 × time − 7
That example team drives 22 cm every second and loses 7 cm getting up to speed. Your two numbers will be different. The shape stays the same.
distance = 22 × time − 7
y = 22x − 7
Visitors who know algebra recognize the second line. Visitors who don't understand the first one. Put both up.
Pick one. Both are fine. Option A is faster and keeps your handwriting on it.
Lay your Distance Lab sheet flat. Shoot straight down, not at an angle. Good light, no shadow from your own head. Upload it to Canva and crop to just the graph.
Check: can you count five separate dots in the photo? If not, go over them darker with a pen and shoot again.
Click Apps → search Charts → pick a scatter or line chart. Type your five drive times down one column and your five actual distances down the other.
Label the bottom Drive time (seconds) and the side Distance (cm). A graph with no labels tells a visitor nothing.
Stand up. Back away from the screen until you are about six feet from it. That is where a visitor will stand.
Any box you can't check, fix it before you move on. Bigger text is almost always the fix.
Separate from the poster. One sheet of paper, thick marker, taped to the wall. Tomorrow the class lines all of these up and compares them.
Two things only. Nothing else goes on this sheet.
Walk to the far wall and turn around. Read your own sign out loud.
Could you read it from back there? YES NO
If no, take it down and write it bigger. This is the whole point of the sign.
