That said, balsa wood can be treated with a waterproof sealant to aid in extending its life in water-based projects. Engineering students frequently use this wood to build model structures and then test them for weight-bearing capacities. However, due to its soft and lightweight nature, balsa wood is much more prone to damage such as dents, scratches and even breakage, making it more delicate than basswood. 8), Create solutions to problems by identifying and applying human factors in design. Next, cut two pieces of balsa wood at a 45-degree angle. MS-ETS1-1. Basswood is much more affordable and easier to find, making it an attractive option for furniture makers as well as crafters.
