The lab explored physical properties of building materials, with wood supporting our hypotheses for Tiny World. Material density is vital for structural integrity, and choices depend on environmental factors like weather and climate.
In this lab, we investigated and observed the physical properties of various building materials, including wood, clay, brick, iron, aluminum, copper, and nickel. We examined flexibility, magnetism, thermal conductivity, electrical conductivity, and density for each material. For our Tiny World house, we used wood, a flexible and non-magnetic material, which aligns with our hypothesis. The densities chosen for the walls and floor were reasonable for stability and structural integrity.
The density of a building material is crucial when constructing homes or architectural structures. It affects the overall weight, strength, and durability of the structure. In real-world scenarios, considering the environmental conditions is vital. For latches, materials like wood or aluminum might be unsuitable due to their susceptibility to warping or corrosion.
Copper exhibited the highest thermal conductivity, making it suitable for applications like wiring. Aluminum demonstrated the highest electrical conductivity. This is due to the high mobility of electrons in metals, allowing efficient electrical conduction.
Considering past environments and weather conditions, in cold climates, materials with high thermal conductivity like brick could help retain heat, while in hot climates, materials with lower thermal conductivity like wood might be preferable. These choices optimize energy efficiency and comfort
