Chemistry Unit 1

Big Idea:

Explain safety and logistical expectations of an appropriate science investigation and mathematical procedures.

Student Expectations:

Priority TEKS

C.1(A) demonstrate safe practices during laboratory and field investigations, including the appropriate use of safety showers, eyewash fountains, safety goggles or chemical splash goggles, as appropriate , and fire extinguishers.

C.1(B) know specific hazards of chemical substances such as flammability, corrosiveness, and radioactivity as summarized on the Safety Data Sheets (SDS)

C.2(E) plan and implement investigative procedures, including asking questions, formulating testable hypotheses, and selecting equipment and technology, including graphing calculators, computers and probes, electronic balances, an adequate supply of consumable chemicals, and sufficient scientific glassware such as beakers, Erlenmeyer flasks, pipettes, graduated cylinders, volumetric flasks, and burettes

C.2(F) collect data and make measurements with accuracy and precision

C.2(G) express and manipulate chemical quantities using scientific conventions and mathematical procedures, including dimensional analysis, scientific notation, and significant figures

C.2(H) organize, analyze, evaluate, make inferences, and predict trends from data

C.2(I) communicate valid conclusions supported by the data through methods such as lab reports, labeled drawings, graphs, journals, summaries, oral reports, and technology-based reports.

Ongoing TEKS

C.1(C) demonstrate an understanding of the use and conservation of resources and the proper disposal or recycling of materials

C.2(A) know the definition of science and understand that it has limitations

C.3(A) analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student

Student Learning Targets:

• I will perform calculations using scientific notation and standard notation.
• I will perform calculations using significant figures.
• I will perform calculations using unit conversions.
• I will define metric units and prefixes and explain how metric units are used in measurement.
• I will distinguish between accuracy and precision in a given set of data.
• I will identify hazards and select the appropriate safety equipment.
• I will summarize the information on the Safety Data Sheets (SDS)
• I will communicate conclusions in written and graphic forms.
• I will use essential vocabulary of the discipline to communicate conclusions
• I will use appropriate writing practices consistent with scientific writing.
• I will present scientific information in appropriate formats for various audiences.
• I will use various methods for communicating conclusions.

Essential Questions:

• Why is it important for a scientist to maintain thorough documentation of all work?
• What should be considered when appropriately conducting a scientific investigation and why?
