Lesson Plan Day: 21 

 

Teacher: P. Kirk

Subject: Science

Course: Chemistry

Topic: Using Significant Figures in multiplication and division calculations.

 

 NGSS:

C.PM.1: Atomic structure, Evolution of atomic models/theory
C.PM.2: Periodic Table

  

Objectives:

Students have learned how to round. Unfortunately, they did not learn when to round or why to round. We round to the significance of the measuring devices we use.  Apply the multiplication and division rule to determine the sig figs in the resulting answer of this kind of calculation.

  

Vocabulary:

 Significant Figures

 

Student:

The students will learn and practice the identification of significant figures. There are five rules for the identification of sig figs. They will apply the multiplication and division rule to determine the sig figs in the resulting answer of this kind of calculation. Students will practice these activities on EA2B.

  

Teacher:

The teacher will use notes and example problems to demonstrate the application of the five rules and identify sig figs and the multiplication and division rule to determine the sig figs in the resulting answer of this kind of calculation. Teacher will create, publish and evaluate progress on EA2B.

 

 Resources:

Sig Fig Notes, Sig fig introduction sheet copies, Sig Figs Level I / Sig Figs Level II work sheet copies, EA 2B

 

Evaluation:

Sig fig introduction, Sig Fig Level I are practice sheets. Students will check answers. Teacher will monitor student progress. Sig Fig Level II will be collected for a grade. There will be a grade taken on EA2B. There will be a quiz covering the combined skills of sig fig identification and sig figs in calculations (addition and subtraction) and (multiplication and division.)
