SPEED OR VELOCITY

Description

This lesson pack contains a lesson plan and a set of activities which will develop the childs ability to observe, measure, compare, analyze and make generalizations about the difference between speed from velocity.

Target Audience

Grade Five Science and Health Pupils

Subject Matter/Learning Competencies

Speed or Velocity ?PELC (RBEC) Science and Health VI Unit IV-Energy- Third Grading Period 10. Differentiate Speed from Velocity10.1 Measure the speed of an object in motion10.2 Identify the specific direction of a moving object10.3 Measure the velocity of a moving object

Duration

40 minutes

Objectives

After doing all the activities, the pupils will be able to:

Measure the speed and velocity of a moving object.

Identify the specific direction of a moving object.

Differentiate speed from velocity.-

3Preparation Provide pupils with enough background knowledge and hands on activities regarding the proper use of the stopwatch.

Prepare in advance the appropriate place for the outdoor activity .

Measure a 20 meter distance on the ground ahead of time. This is done in order to save time.

Procedure

Divide the class into groups of four to five members. Each group will choose its speaker , manager and director.

Let the managers get the activity sheets and the materials needed. Remind them to return the materials as soon as they are through with the activity.

Remind pupils to follow strictly the time allotment.

The time frame for each activity is 10 minutes. Publishing and reporting of group responses will be given 5 minutes.

Let the pupils record the results of the activities on the Record Sheet.

Publish the data gathered and report the findings.

Teaching Hints

Allow pupils to use the calculator for computation of speed.

Provide a battery operated toy car for this activity.

Time allotment should be followed strictly for each activity so that the activity will be finished on time.

After all groups have reported, confirm the answers given and supply any additional information needed.

LESSON PLAN IN SCIENCE AND HEALTHGRADE FIVE

Objective

After doing all the activities, the Grade VI pupils will be able to differentiate speed from velocity

Subject Matter

Speed or Velocity, Science for Active Learning, pp. 226 - 230

Science Ideas: 1. Speed is distance traveled per unit of time. 2. Velocity is the speed of an object moving in a particular direction.

Processes stressed: Observing, measuring, inferring, explaining

Materials:

stopwatch activity sheet meter stick battery-operated toy car tape measure record sheet calculator

Learning Activities

Review/Checking of Assignment Allow a member of each group to read or discuss their answers to the assignment.

Lesson Proper

Motivation Ask: How far is your home from school?

How do you get to school? Do you walk, ride, or run? If you walk, how long does it take you to get to school?

Presentation/Development Divide pupils into small groups of three to four members and let the manager get the activity sheet and other materials. Pupils perform the different activities simultaneously. Publish and record the data gathered.

Ask: What are the things to be considered when we talk about speed? (Distance traveled and time spent)How can we get the running and the walking speed of an object?How can we get the velocity of a moving object?What are the things to be considered when we talk about velocity? (Emphasize speed and specific direction.)

Confirm pupils responses and give additional information needed.

Say:Speed is written as, meters/second orm/sec.Velocity is written asmeters/second north orm/sec.n.

GeneralizationAsk:

What is the difference between speed and velocity?

Expected answersSpeed is the distance traveled per unit of time.Velocity is the speed of an object moving on a particular direction.

Application

Average and slow learners:(To be done orally)

Directions:

Tell which refer to speed and which refer to velocity. 1. 30 km/hour 5. 13km/hour south

2. 18 km/ hour north 6. 270 m/min

3. 4m/sec east 7. 19m/sec west

4. 16 km /hour 8. 5m/sec

Evaluation

Average and Slow learners

Directions:

State which refers to speed and which refers to velocity. On the space provided for write S if it refers to speed and write V, if it refers to velocity.

1. A ball rolls 50 cm in 23 sec.2. A runner covers a distance of 100m in 10 sec.3.A car is going at an average speed of 50 km/ hour.4. A tricycle travels at the rate of 5 km/h covering a distance of 10 km North.5.Joanne walks 1000 meters to school in 15 minutes.6. Matt drives his motorcycle at an average speed of 15 km/hr.7. The snail covers a distance of 5 meters in an hour.8. Patrick ran after the dog, 5 m/sec East.

Assignment

Write five situations wherein speed is measured and another five wherein velocity is measured.

ACTIVITY A

WALKING SPEED AND VELOCITY

Objective

Measure the speed and velocity of an object in motion

Materials for each group

Stopwatch Meterstick/tapemeasure Calculator Activitysheet Recordsheet

Procedure

1. Measure 20 meters on the ground and mark the starting and the finish line.2. Let a classmate walk the distance at the signal GO. Use a stopwatch to find how long it

takes. Take note of the specific direction. Have one more to walk the distance. 3. Divide the distance walked by the time spent to find the walking speed. Use a calculator.4. Find the velocity, which is the speed of the object moving on a particular direction.5. Record the data gathered on the record sheet and prepare a short report about your

findings.

TIME FRAME: 10 MINUTES

ACTIVITY B

RUNNING SPEED AND VELOCITY

Objective

Measure the speed and velocity of an object in motion

Materials for each group

Stopwatch Meterstick/tapemeasure Calculator Activitysheet Recordsheet

Procedure

1. Measure 20 meters on the ground and mark the starting and the finish line.2. Let a classmate run the distance at the signal GO Use a stopwatch to find how long it

takes.Take note of the specific direction. Have one more to run the distance.3. Divide the distance ran, by the time spent, to find the running speed. Use a calculator.4. Find the velocity, which is the speed of the object moving on a particular direction.5. Record the data gathered on the record sheet and prepare a short report about your

findings.

TIME FRAME: 10 MINUTES

ACTIVITY C

HOW FAST IT GOES?

Objective

Measure the speed and velocity of an object in motion

Materials for each group

Stopwatch Meterstick/tapemeasure Calculator Batteryoperatedtoycar Activitysheet Recordsheet

Procedure

1. Mark 8 meters on the floor.2. Let a toy car run from 0 to 8 meters.3. Use a stopwatch to find out how long this takes. Take note of the specific direction.4. Divide the distance traveled by the time spent to find the speed. Find the velocity which

is the speed of the object moving on a specific or particular direction.5. Record the data gathered on the record sheet and prepare a short report about the

findings.
