In this activity, you will research how atomic and molecular structure is important to how materials function. You will research at least two designed materials. Then you will present your findings in a written report. In your report, you must include graphical or mathematical representations, or both, of key points. Find and analyze scientific and technical information about why the molecular structure of a designed material is important to how it functions. Convey your findings in a written or oral report.
Conduct research about why the molecular-level structure is important in the functioning of designed materials. You should research at least two examples. Then communicate this scientific and technical information using written text and graphics.

What is the difference between bonding forces holding compounds together and other attractive forces? What types of chemical bonding and intermolecular forces do the materials have?

Predict the general properties of your materials based on the types of bonds they have. Properties include melting point, boiling point, and conductivity.

Analyze your materials' specific physical and chemical properties. Properties include color, density, viscosity, buoyancy, boiling point, freezing point, conductivity, and reactivity.

Designed materials need to meet certain requirements. When designing new products, why is it important to study the properties of the materials?

Analyze, evaluate, and critique scientific explanations regarding the functioning of designed materials. You should communicate and apply scientific information that comes from various sources, such as published journal articles. In addition, you should evaluate scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing. For each source, consider the following questions:

Choose one of your sources as a sample, and provide your teacher with answers to these questions for that sample source.
What is the purpose of the source of the information? (Note: A source should document scientific research rather than report news, provide entertainment, or market products.)

When was the information published? (Note: It should have been written in the recent past.)

Who was the information written for? (Note: Most articles with scientific explanations should be for scientists, educators, or students rather than for the general public.)

What are the reputations of the sources of the scientific information? (They should be scholarly, peer-reviewed, nonpolitical, noncommercial, and impartial — not biased.)

What type of supporting documentation does the article provide? (Note: It should contain charts and graphs of data and illustrations, as well as several cited references to credible sources.)

Read each scientific article at least two times to be sure you understand the information it contains. Take detailed notes about each article you want to use in your project. You can record and organize these notes on note cards or sheets of paper or in electronic files. Be sure that each entry clearly references the name of the author(s) and the titles of the source and the article.

Develop a list of at least eight annotated references, using proper American Psychological Association (APA) style. In each annotation, you should summarize the purpose of the source, evaluate its credibility, and explain how it will help you plan and complete your project.

you need to write your report. Your report should communicate why the molecular-level structure is important in the functions of designed materials and evaluate scientific explanations regarding the materials. Your report should use at least two different methods of communication such as written text, drawings, and graphs.
Start by writing a detailed outline of your report. Your report must follow APA style and include, at minimum, the following sections: title, introduction, main body, conclusions, and references cited. Your report is due on the day of the unit test.
