2.04 Thermal Energy and Chemical Change Lab Report PLEASE HELP!!!! 100 POINTS ASAP!!!

Instructions: In this engineering lab, you will build trains to reach the finish line without crashing. You will need to repeat tests of your device to make sure it does not need to be redesigned or improved. Complete all the areas shaded in purple.
Note: If you cannot complete this lab as directed, please contact your instructor for assistance.________________________________________

Part 1: Thermal Energy
Lab Objective:
The goal of the lab is to build steam engine trains that can carry cargo to the end of three different tracks.

Part 2: Energy Engineers
To create working trains, you will need to learn about the different parts that power the train. Take notes on each part.
Is this an endothermic or exothermic process?
Evaporative cooler
Woodburning heater
Steam engine
Part 3: Runaway Train
You will need tools to design a train that can make it to the target station without crashing. Select each tool in the virtual lab and describe how it could help your train design.
Steam Engine
Train car
Spring
Helium balloon
Wood-burning heaters Evaporative coolers


Design Ideas
Describe three design ideas you have for your train. But first, consider these design limitations.
• Each train needs at least one train car, one panda, one cargo box, and a steam engine.
• The train tracks will have two hills.
• One train track has some tracks missing.
• You can use additional tools in your train design to get to the finish line.
Train 1 on Track 1 Train 2 on Track 2 Train 3 on Track 3



Data:
Record the results of each of the test run you make to the train station. Be sure to describe any changes you make to your train to improve your design between test runs.
Train 1 on Track 1 Train 2 on Track 2 Train 3 on Track 3
Trial 1
Did your train make it to the station?
Trial 2
Describe any new tools you added to your train.

Did your train make it to the station?
Trial 3
Describe any new tools you added to your train.

Did your train make it to the station?
Analyze Data and Conclusion:
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? If yes, describe the design of one successful train.


2. What are the benefits of using repeated trials and replication in a scientific investigation?


3. Which train track presented the most challenge to getting the train to the station?


4. How do endothermic reactions differ from exothermic reactions? Be specific.

Answer:

Step-by-step explanation:

Part 2: Energy Engineers

For each part (Evaporative cooler, Woodburning heater, Steam engine), determine if it's an endothermic or exothermic process.

An endothermic process absorbs heat from its surroundings.

An exothermic process releases heat into its surroundings.

Part 3: Runaway Train

Describe how each tool can help your train design. For example:

Steam Engine: Provides power to the train.

Train car: Carries cargo.

Spring: Could be used for suspension or propulsion.

Helium balloon: Could potentially lift the train.

Wood-burning heaters: Could provide additional heat for a steam engine.

Evaporative coolers: Could help regulate temperature.

Design Ideas

Describe three design ideas for your train, considering the design limitations mentioned. For example:

Use a helium balloon to lift the train over obstacles.

Utilize a strong spring for better suspension.

Incorporate wood-burning heaters to increase steam engine efficiency.

Data

Record the results of each test run for each train on their respective tracks.

Describe any changes you make to your train between test runs to improve your design.

Analyze Data and Conclusion

Discuss whether any of your train designs were able to reach the station without crashing. If yes, describe the design of one successful train.

Explain the benefits of using repeated trials and replication in a scientific investigation. This is about ensuring the reliability and consistency of your results.

Reflect on which train track presented the most challenge to getting the train to the station. Describe the difficulties you encountered.

Explain how endothermic reactions differ from exothermic reactions. Endothermic reactions absorb heat from their surroundings, while exothermic reactions release heat into their surroundings.

Feel free to provide more specific details or questions if you need further assistance with any particular part of your lab report.
