They should also be able to distinguish between physical and chemical properties, and be familiar with the periodic table of elements. Students should be familiar with the composition of matter and be able to define elements, compounds and mixtures. Titanium and Its Alloys (pdf) Visit [ to print or download. International Technology and Engineering Educators Association - Technology Thus technology use varies from region to region and over time. Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.Īlignment agreement: Thanks for your feedback! Engineering advances have led to important discoveries in virtually every field of science, and scientific discoveries have led to the development of entire industries and engineered systems.Īlignment agreement: Thanks for your feedback! The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values by the findings of scientific research and by differences in such factors as climate, natural resources, and economic conditions. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. Gather, read, and synthesize information from multiple appropriate sources and assess the credibility, accuracy, and possible bias of each publication and methods used, and describe how they are supported or not supported by evidence.Īlignment agreement: Thanks for your feedback!Įach pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.Īlignment agreement: Thanks for your feedback! Substances react chemically in characteristic ways. This lesson focuses on the following Three Dimensional Learning aspects of NGSS: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.Ĭlick to view other curriculum aligned to this Performance Expectation Determine the advantages of using alloys compared to pure substances.Compare and contrast the physical and chemical properties of alloys and elements.Define and classify alloys as mixtures.In this lesson, students experience the relationship between materials science and engineering through the investigation of alloys.Īfter this lesson, students should be able to: While a materials scientist investigates the correlations between the structure and properties of a given substance, a materials engineer uses this information to identify the most efficient way to enhance the properties of a material through the redesign of its structure. Materials science and materials engineering go hand-in-hand when it comes to studying and designing materials for various applications.

This engineering curriculum aligns to Next Generation Science Standards ( NGSS). Pre- and post-assessment handouts are provided. Students use the associated activity to practice their understanding by researching and communicating their findings of various alloys to be used in NASA aerospace applications. Students learn that engineers investigate the structures and properties of alloys for biomedical and transportation applications.

Students define and classify alloys as mixtures, while comparing and contrasting the properties of alloys to those of pure substances.
