Unit

A Powerful Workout--LAB

Local Objective

At the end of the lab, students will be able to...

a. Calculate the work and power used to climb a flight of stairs.

b.  Compare your work and power with that of a 100 watt light bulb.

Objective used to evaluate students

Yes

Assessment Activity

Informal Evaluations--Teacher will observe during class discussion and questioning as students calculate work and power.  Teacher will observe to make sure students stay on task. 

Independent Practice--Students will be following the procedure for this activity on their own.  Teacher can make a formal assessment on their work and ability to read and follow directions.

Assessment--A final assessment can be made of students answers to analyzing their results and drawing conclusions.

Learning Activity

The students will:

1.  Review all safety cautions and icons before beginning the lab activity.  ***Students who have asthma or any other respiratory problems should not perform this lab.  (This is not a race.)

2.  Using a chart, follow the procedure outline listed on pages 114-115 of the Holt Science and Technology (M).

3.  Conclude this activity by analyzing their results and drawing conclusions.  During their activity, write down notes about the lab, those will be used to analyze and draw conclusions.

Instructional Method

The teacher will:

1.  Guide students during the review of all safety cautions and icons before beginning the lab activity.

2.  Guide students in following the procedure outline listed on pages 114-115 of the textbook.  Help students to complete their charts correctly.

3.  Guide students in analyzing their results and drawing conclusions about the experiment.  Show students how to use notes to analyze and draw conclusions.
