Core Skills Analysis
Science and Engineering
- Vienna began distinguishing a successful engineering solution from an unsuccessful one by explaining that a wall collapsing immediately would not work.
- She identified performance criteria—holding weight and surviving catapult impacts—that connect the wall’s design to its intended purpose.
- Vienna recognized that historical context can influence design requirements, noting that the wall needed to withstand conditions it might have faced “back in the day.”
- She is beginning to consider practicality through ideas such as a solution making sense and being easy to make, but measurable criteria, constraints, and comparing advantages and disadvantages remain developing skills.
Language Arts
- Vienna used explanation and reasoning to justify her engineering ideas rather than simply naming a preferred design.
- Her statement about a collapsing wall communicated a clear cause-and-effect relationship between structural failure and an unsuccessful solution.
- She practiced using evidence from the design challenge—holding weight and surviving catapult hits—to support her judgment about what the wall must do.
- Her use of phrases such as “I guess both” shows she is still refining confidence and precision when explaining competing requirements.
History
- Vienna connected the engineering problem to historical walls and recognized that past structures had specific defensive purposes.
- Her reference to catapult attacks shows emerging understanding that technology and conflict can shape architectural design.
- She began considering how historical conditions determine what counts as a reasonable solution, rather than judging a wall only by appearance.
Tips
Tips: Help Vienna turn her ideas into a simple engineering design brief. Together, list criteria such as holding a specified weight and surviving a set number of catapult hits, then identify constraints such as available materials, time, and size. Invite her to rank each criterion by importance and explain the trade-offs. After building, have her record predictions, test results, and one design change, using a pros-and-cons chart to compare versions.

Try This Next
- Create a design-brief worksheet with columns for criteria, constraints, evidence, and test results.
- Ask Vienna to predict how many weights and catapult hits her wall will withstand, then compare predictions with results.
- Draw two wall designs and label one advantage and one disadvantage for each.
- Write a short claim-evidence-reasoning response explaining which wall design works best.
