Agenda for the Week…Agenda for the Week…

Today is the official beginning of our first major unit of study together:

“FORCES AND MOTION”

Pre-test on Forces and Motion

Introduction into the Unit

Page 5: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Agenda for the weekAgenda for the weekFor this unit, I am going to try to have at

least one mini lab per day to get you up and out of your seat “DOING SCIENCE”

You must have exceptional behavior and use your quiet partner voices for this to work. REMEMBER: You all want science to be fun, but it has to be a safe and orderly environment.

Many of the materials (cars, balls, etc.) I have borrowed from my children’s toy basket. PLEASE TAKE EXCEPTIONAL CARE OF THESE ITEMS.

Lost or stolen materials = NO MORE LABS

Agenda for the Unit…Agenda for the Unit…

In addition to mini-labs, Thursday you may have an outside lab.

In order to earn this privilege, you will need to meet class expectations as well as complete a pre-lab sheet

I will continue to do a super fun activity at the end of every week if as your behavior and attitude warrant me doing so.

Today we are going to…Today we are going to…Learn some of the very basic

vocabulary◦Position, Motion, Distance, and

SpeedWatch a couple of videosTake some guided notesParticipate in a Mini-LabLearn how to calculate speed

Thinking together….Thinking together….SILENTLY each person should chose

an object in the room…

SILENTLY think of how you could describe to another person how to get to that object from the classroom door….

With the person next to you, try to guess each others’ objects by giving your directions to that object

(DON’T SAY THE OBJECT’S NAME!!!!)

PositionPosition

POSITION is the location of a place or object.

Often you describe where something is by comparing its position with that of something elseCan someone describe how they used this technique in the last exercise?

Page 11: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Reference PointsReference PointsEach time you identify the position

of an object, you are comparing the location of the object, you are comparing the location of the object with another location or place

The object or location to which you compare other objects or

locations is called a REFERENCE POINT.

DistanceDistance

DISTANCE is the measurement of two positions

In science, we measure distance in METERS◦Kilometers for long distances◦Centimeters for short distances

Page 14: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Distance can be either Distance can be either straight line or a measure of straight line or a measure of a path taken…a path taken…

Question:How would the distance of the path of this maze be different from a straight line measurement?

Page 15: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

MOTION…MOTION…

MOTION is the change of position over time.

Motion can be either:

VERTICAL HORIZONTAL

Page 16: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

SOME IMPORTANT THINGS SOME IMPORTANT THINGS TO NOTE….TO NOTE….

Motion does NOT indicate how quickly something changed position◦This is SPEED, something we will learn in

a moment

Motion can change direction

Page 17: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Check for Check for Understanding…Understanding…1. What is the name for the location

of a place or object?2. How does scientists measure

distance?3. Motion can be __________ or

______________.4. The location or object to which

you compare other objects or locations is the ____________.

Page 18: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Finally, what is speed???Finally, what is speed???Speed is a “rate of motion”

It is measured as a distance over time

SPEED = DISTANCE TIME

◦Or speed = m/s

Turn to page D16 in the textbook. You will work with in groups of 3 to complete the short task “EXPLORE SPEED”. You have 5 minutes to complete this and turn in the “WHAT DO YOU THINK?” questions as part of your exit ticket.

2 people to roll ballsTeam Captain will use stopwatch to record time.

DISCUSSION: SPEEDDISCUSSION: SPEEDYou actually already know

a great deal about speed. What does the speed limit

on the road stand for?MILES PER HOUROr miles hourRemember our formula

for speed?

Calculating SpeedCalculating Speed

A wheelchair racer completes a 100 meter course in 20 seconds. What is his speed?

Page 23: Forces and Motion Mrs. Anna Ward Ridge Road MS. Warm Up Copy onto Page 13 King Henry Died Unexpectantly Drinking Chocolate Milk

Calculating SpeedCalculating SpeedIf a car travels 400 meters in 20

seconds how fast is it going?

Answer: 20 m/s

EXIT TICKETEXIT TICKET

1. Mr. K’s class is 10 meters away. If it takes you 8 seconds to get there, what is your speed?

2. The Gym is 100 meters away. If it takes you 90 seconds to walk there, what is your speed?
