In this practical project, students will construct models of different geometric shapes and test their strength using weights. This experiment will help them understand the principles of structural stability and geometry in architecture. By comparing the strength of various shapes, students will gain insights into engineering design and physics.
If I build structures using different geometric shapes, then the triangular shape will support the most weight due to its stability.

Cut straws into equal lengths (about 5 inches).
Construct various geometric shapes (triangles, squares, etc.) using straws.
Attach the shapes to a cardboard base securely.
One at a time, place weights on each structure until it collapses.
Record the maximum weight each shape can support.
Compare the results to see which shape was the strongest.
Discuss the reasons behind the observed strengths and weaknesses.
Ensure to clean up the materials used after the experiment.
The triangular shapes will likely withstand more weight than square or rectangular shapes, showcasing the concept of structural integrity.
