Short explanation
In the subtopic Alloys as useful materials, this learning objective focuses on compare high carbon steel and low carbon steel in terms of strength, brittleness and shaping. (Chemistry only). Within Using materials, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only, steel, high carbon steel, and low carbon steel. High Carbon Steel means an alloy of iron that contains a higher percentage of carbon, resulting in increased strength and brittleness. Avoid students often confuse high carbon steel with low carbon steel, thinking they have the same strength and brittleness; instead remember that high carbon steel is stronger and more brittle, while low carbon steel is more malleable and easier to shape. For exam answers, compare the properties of high carbon steel and low carbon steel by creating a table that lists their strength, brittleness, and shaping capabilities.
