Lesson Plan

Period #2 Chemistry, Matter & Observations

Materials : Textbook : Chemistry - Nelson

Safety Quiz, Laboratory Write up Sheet, Copper Lab

Review : Lab Write ups from Science 9.

Objectives : students should be able to :

1.9 define matter

1.10 describe chemistry as the science concerned with the properties, composition, and behavior of matter

1.11 describe and give examples of a variety of forms and properties that matter can exhibit

1.12 distinguish between observation and interpretation

 

Part I - Chemistry, Lab Reports & Classifying Knowledge - Notes :

Short Quiz on Safety and Good Lab Techniques

• hand out test, students should take about 15 minutes to complete
• when finished, they can look over chapter I on Nelson text

Why learn Chemistry? - Discuss possible careers for students studying chemistry

• show overhead of jobs page 1-8

Introduction to what Chemistry is

• ask students what they think chemistry is
• discuss and give notes on chemistry, and scientific method on page 1-9.
• show overhead of a model for scientific problem solving one page 1-10 or notes (page 24 - Nelson)

Lab Reports

• relate scientific problem solving to Formal Lab Reports
• handout sheet on Lab Reports - go over very thoroughly
• example report can be found on page 729 of the Nelson Text

Classifying Knowledge

• differentiate between observation and interpretation and discuss and give notes on empirical and theoretical knowledge starting on "CLASSIFYING KNOWLEDGE", on page 1-9 of notes
• show overhead of knowledge classification page 1-11
• discuss and give notes on qualitative and quantitative observations also on page 1-9 of notes.
• relate this to lab report write ups (what goes where)
• Copy Table 1.2 into Notebooks page 34 of Nelson on independent and dependent variables

Exercise :

Do questions 31-34 page 34 of Nelson.

Evaluation :

Unit One Exam

Question 31-34 page 34 of Nelson

Part II - Observations and Laboratory Write-ups - Introduction and Notes

Demo proper Use of Bunsen Burner - See Nelson Page 734

Demo - Burning Magnesium - Give Notes starting "BURNING MAGNESIUSM", on page 1-12.

Write up of Lab Report for Magnesium Burning

• go through proper format for lab write up as a class, use "Sample Lab Write Up- Combustion of Magnesium on pages 1-13, and 1-14 in notes.
• brainstorm on how to organize data, and what should go into analysis

If time, students can start copper lab (see handout, PRACTICE IN SCIENTIFIC OBSERVATIONS)
