Copy the following table in your science notebookAdvantages and Disadvantages of Using Different Materials

Material Data Cards

Note: Measurement units appearing on the Material Data Cards are primarily in units of the English system rather than the International System (SI) of Units. This is because much of the data are compiled by U.S. industries and are described in English tons, pounds, gallons, and British thermal units (BTUs), and the data would be comparable for students who do additional research.

Note: that the energy data is shown in units of kilocalories (kcal). One kilocalorie is equivalent to 1,000 calories or 1 Calorie.

Note: that 1 Calorie is the metric unit of measurement of stored energy in food.

Remember: Properties are the nature of a material, such as the physical qualities of color, hardness, state, and density. Also consider what the material can do such as conduct electricity.
