Core Skills Analysis
Engineering and Design
Chloe assembled two small tables, first following instructions with hand-over-hand support to identify parts, orient components, and determine how screws should be placed. On the second table, Chloe responded to questions by identifying a rod and a square tube and using the instructions to decide how the parts fit together. Chloe then recognized that the tabletops needed added support to stay stable in the flat position and helped develop and fit 3D-printed parts, experiencing how a design can be improved through testing.
Mathematics and Measurement
Chloe used a caliper to measure the table and the parts being designed, applying measurement to a practical construction challenge. Chloe compared those measurements with dimensions in CAD software and checked them again with the caliper, connecting digital dimensions to real objects. This process offered practice in accurate measuring and in using repeated checks to help parts fit.
Science and Technology
Chloe explored how tools can make work easier by discussing why tools are used and how a tool can provide more leverage than hands alone. Chloe also worked with CAD software to create parts from basic shapes and use negative shapes to form cutouts, then saw the digital designs become 3D-printed objects. Fitting the printed parts to the table connected digital modeling, physical objects, and practical problem-solving.
Tips
Tips Turn this project into a mini design cycle by asking Chloe to sketch the tabletop support problem, predict what shape might hold the top steady, and explain the reasons for the design. Invite Chloe to compare two possible support shapes in CAD, measure each carefully, and test the printed parts on the table. Explore leverage with a simple supervised demonstration using a ruler as a lever and small objects as loads, discussing how changing the position affects effort. Finish with a short design journal containing measurements, a labeled drawing, what happened during the fit test, and one improvement Chloe would try next.
