What are your observations…?

What caused this accident? What may have caused this multi car wreck?

Talk to your partner about 3 possible things that may have contributed to the accident.

Have you been in an accident?

Have you seen an accident?

Did you know…

What happens in the first fatal second after a car going 55 mph hits a solid object?

The front bumper collapses

The grille collapses

First 1/10th of a Second

2/10th of a Second

The hood crumbles and strikes the windshield

Spinning rear wheels lift from the ground

Fenders wrap around each other causing the frame to stop

The driver legs stiffen and snap at the knees

3/10th of a Second The steering wheel starts to disintegrate

The steering column aims for the driver’s chest

4/10th of a Second

Two feet of the car’s front end is wrecked

Rear end of the car is still moving at 35 mph

Driver’s body is moving 55 mph

Driver and passenger can experience serious injury

5/10th of a Second

Objectives of Today’s Lesson:Understand reaction time

Measure reaction time

Record appropriate data

Analyze data

Compare your reaction time to other situations

FOOD FOR THOUGHT…

How is reaction time related to distracted driving?

Reaction time

Reaction time is a time interval

Gun firing = stimulus

Runner movement = response

Time interval = how long does it take a runner to start after the gun

Where is reaction time important? Sports: Softball, Baseball, Football, Gymnastics

Games: Cards, Board games, Activities

Video Games

Physical Activity Tests

Driving

Let’s Test Your Reaction Time

Get into a Team of 2

Test 3 times for each hand

Record your results on lab paper

Determine averages

What about Computer Skills?

With your partner test out the computer activity

Record your times in the data table

Is your time the same or different?

If different, why is your time not the same as the ruler test?

Try the second Computer Test

Is it the same or different from the other computer test?

Simulation Test 1 Let’s try a driving situation

Try to brake your vehicle and DON’T hit the pedestrian

You LOSE if you see the shatter screen

You WIN if you brake before the shatter screen appears

Watch each video 3 times

Record your results

Simulation Watch the simulation

Simulation Test 2 Try the Simulation again 3 times

Have a phone in your hand

Watch the phone, dial or text during the simulation

Record your results…can you stop in time?
