I can’t run the Gizmo for you, but here’s a clear step‑by‑step you can follow and some tips for collecting useful data and analyzing it.

Procedure to collect rows in the table
1. Open the Gizmo and set Burt’s mass to 50 kg.
2. Enter "50" in the Mass [kg] cell for row 1 (or leave it blank if you’ll use the magic wand to fill it).
3. Press PLAY and watch the collision.
4. Open the Collision results (or results panel) and note how many snowmen Burt knocks over.
5. Record that number in the Kinetic Energy [Snowmen Destroyed] column for row 1 (or click the table’s magic wand to capture the current values into the table).
6. Press RESET. Change Burt’s mass to the next value.
7. Press PLAY and either click the magic wand in the table to add the new data automatically, or manually type the mass and the number of snowmen knocked over into the next row.
8. Repeat for all remaining masses you want to test.

Suggested masses to test
- Use a spread of values so you can see the trend. Example set: 25, 50, 75, 100, 150 kg (include the initial 50 kg row).
- If you want finer resolution, try: 10, 25, 50, 75, 100 kg.
- Do at least 4–5 different masses.

Data-quality tips
- Keep everything else constant (launch speed/angle, friction, snowman arrangement). Only change mass.
- Do 2–3 trials per mass and average the number of snowmen knocked over to reduce random variation.
- Use the magic wand after each run to ensure consistent, error-free data capture.

Quick physics reminder (helps with interpretation)
- Kinetic energy KE = 1/2 m v^2. If launch speed v is held constant, KE is directly proportional to mass m.
- If snowmen knocked over is a proxy for KE, expect the number of snowmen knocked over to increase roughly in proportion to mass (assuming speed doesn’t change and the knock‑over threshold is linear). Real results may show step changes (you can only knock over whole snowmen).

What I can do next
- If you tell me the numbers you record for each mass, I can help you: average trials, plot the relationship, fit a line, or interpret whether snowmen destroyed is proportional to KE.
- If you want predicted values, give me the collision result for one mass (e.g., mass 50 kg → N snowmen) and I can predict counts for other masses assuming proportionality.

Do you want a suggested list of exact masses to use and a blank table layout to copy into the Gizmo?
