Define the Problem:
The goal of the engineering lab was to understand how Thermal Energy and Chemical Change work
Criteria and Limitations:
In this section, please list at least three criteria that must be met by your train design. Also include
any limitations that could prevent it from getting its cargo to the station.
Criteria Limitations
I need to have wood burning
heaters
If I don’t have springs then I wouldn’t get my cargo to the
station
I need to have helium balloons If I don’t have steam engines then I cannot move at all.
I need Evaporative coolers If I don’t have an empty train car then I wouldn’t be able to put
it anywhere.
Design Ideas—Pros and Cons:
In this section, describe three design ideas you have for your train. List at least one pro (a positive)
and one con (a negative) for each design option.
Description of Train Design Pro Con
Train One Spring, Helium Balloons, and Wood burning
heaters
Wood burning

Train Two Panda, Cargo boxes, and Steam engines Panda Steam engines

Three
Evaporative coolers, empty train cars, and a
spring.
Empty train cars Spring
Data:
Record the results of each of the test runs you make to the train station. Be sure to describe any
changes you make to your train between each test run.

One
It went to the finish

It also went to the finish line My cargo reached the

I crashed because I didn’t use any
springs.

Three
My cargo has
reached the station
I added springs to my train. I failed
because I didn’t add the balloons.
I didn’t add balloons so
that’s why I failed.
Analyze Data and Refine Design:
This section will include an analysis of your test results and plans for redesigning your train. Please
write in complete sentences.
1. Were any of your train designs able to get their cargo to the train station without crashing?
Yes, my first train design was able to never crash because it had helium balloons to float up,
springs to avoid the impact of the hill, and a Wood burning heater.
2. Which of your criteria presented the most challenge to getting the train to its goal, and why?
My second criteria presented the most challenge because If I put the helium balloons, I didn’t
put the springs. If you don’t have helium balloons and springs together then you cannot get
your cargo to the station
