Day 6 - Extension:  Calculating Mass From Experimental Data                                                                                                          

LESSON OVERVIEW

Students will apply use of formulas and equation solving techniques to find the mass of objects.

INSTRUCTIONAL GOALS

 Students will perform the required calculations to find the mass of the objects using the data found in previously completed lessons.

 

 TN STANDARDS

2.6     Apply the concept of variable in simplifying algebraic expressions, solving equations, and solving inequalities.                                               

1.10 Select and apply an appropriate method (i.e., mental arithmetic, paper and pencil, or technology) for computing with real numbers, and    evaluate the reasonableness of results.

4.5 Demonstrate an understanding of rates and other derived and indirect measurements (e.g., velocity, miles per hr. and cost per unit)

 

FORMATIVE ASSESSMENT

Students will be graded on the proper use of equation solving techniques, showing all required work per instructions given during introduction, and completion of all assigned data collection.

 

Opening the Lesson:

       15 minutes

Discuss the use of the formula (F=MA) and the equation solving techniques needed to find the experimental mass of the objects used in this project.  Work practice problems using data from Practice Problems Worksheet provided to ensure students can solve for the required data.

Developing the Lesson:
30  minutes
  1. Provide the students with the data previously collected Average Time Table 1.
  2. Have the students find the Force and Acceleration figures needed to solve the formula F=MA for the mass of each object.  Table 2
  3. Solve for the mass of each object used in the project.

Closing the Lesson:   

                  5  minutes

Students will turn in all work for grading and collection for the next Science lesson.

TEACHING RESOURCES

Table 2  to record calculated data.  Data collected during Lesson 3 (Average Time Table 1), calculators, practice data from Practice Problems Worksheet, pencil and paper.

LAB SAFETY

No safety concerns.

ACCOMMODATIONS FOR SPECIAL LEARNERS

Special Ed and ESL students may work with tutor or other student to perform required calculations.
