This document provides an agenda for Day III of a Chemistry I course. It includes plans to debrief a candle lab, have students turn in completed labs and review Chapter 1. There will be a unit exam next week covering all of Unit 1. Students are assigned to complete chapter reviews, study for exams, turn in lab safety agreements and prepare element reports to present in class. Homework includes metric conversions practice and completing a lab write-up.

Dimensional Analysis
Unit 1 Exam will be next week
All Unit 1 Work should be
completed & turned in with your
exam
2. Mass Balance Lab Discussion
What was the largest difference between added
individual masses and the mass of both items
together?
How many times was there a difference?
What explanation do you have for the difference?
What could reduce differences?
How accurate is the scale?
With what precision does the scale measure?
3. Homework
Complete Chapter 2 Review
Study for Chapter 1 & 2 Test
Have Lab Safety agreement turned in
give reports
4. Element Notes
Set up section in your binder to take notes
during Element reports. Take notes on the
following.
Name & Symbol
Elemental Family
When, where and by whom was it
discovered.
Where is it most commonly found.
How it is used.
5. Chapter 2 Review
SI Base Units
Density Calculations
Density = mass/volume
Conversion factors
Percent Error
percent error =
Value(accepted) –
Value
(experimental)/Value
(accepted) x 100
Significant figures
Scientific Notation
Direct proportions
Inverse proportions
6. Homework for Week IV
Complete Chapter 2 Review sections 1 & 2
Complete Metric Conversions
Complete Accuracy and Precision Lab
Write Up
Prepare for Unit 1 Exam
7. Scientific Inquiry
Hypothesis /
Background
State the proposed
phenomena or results
expected in the research
State background
information that supports
thesis or is needed to
justify proposed
investigation.
Connect background info
with thesis – explain why it
connects.
Investigation Design
Step by step procedure for
research
Include detailed materials
list
Include drawings of
unique procedures or
equipment.
Address any safety
issues/risks associated
with the design
8. Scientific Inquiry
Data Collection and
Interpretation
Data is relevant to Design – in
quantity and quality
Data tables and graphs clearly
labeled
Observations are made and
noted.
Data graphed to make
interpretation of Data quick
and easy
Conclusion / Analysis
Hypothesis restated
Results stated quantitatively
and qualitatively to evaluate
hypothesis and or research
design
Background information and
observations/data used to
explain results
Modifications or next steps in
research proposed based on
evaluation of research.
9. Scientific Inquiry
Sharing investigative work
Peer Review – have your work reviewed –
edited by another student.
If your research is original the next step is:
Public Peer Review in Scientific Journals.
10. The Law of Conservation of Mass
Matter cannot be created or destroyed in
chemical or physical changes.
Matter is conserved.
