PBL for Friction and Motion


Scenario:

You and your team's job is to build a race car. Use the different car designs to build the fastest race car you can. Make sure that is the fastest! You must be able to prove that your car is the fastest. Take into account how friction (wind resistance) will effect the speed of your car.


EQ:

How would friction effect how you would build a race car?

Vocabulary:

motion, friction,

Activity:

1. Go to http://www.youtube.com/watch?v=lXQJSvDBgQY and watch how pinewood cars can be designed for speed. Pay attention to the different types of pinewood blocks and the way that they are shaped.
2. Looking at the different pinewood block designs, decide on a block design and build your car. Sketch in your journal the shape and design of the car.
3. Take car to the test track outside on the blacktop. Place test car on the top of ramp and release. A teammate will use the stop watch to time how long it takes for the car to reach the finish line.
4. Record the time in your journal with the sketch of the car that was tested.
5. Go back to the pinewood block designs and choose a different block design to test. Sketch in your journal the shape and design of your second car.
6. Take car to the test track outside on the blacktop. Place test car on the top of ramp and release. A teammate will use the stop watch to time how long it takes for the car to reach the finish line.
7. Record the time in your journal with the sketch of the car that was tested.
8. Go back to the pinewood block designs and choose a different block design to test. Sketch in your journal the shape and design of your third car.
9. Take car to the test track outside on the blacktop. Place test car on the top of ramp and release. A teammate will use the stop watch to time how long it takes for the car to reach the finish line.
10. Record the time in your journal with the sketch of the car that was tested.
11. Test, design, and sketch each pinewood block design until you can prove that you have found the fastest way to build your car.
12. Show your fastest car and how you know that it is your fastest and why it was the fastest.
13. Using Powerpoint, show the sequence of car design from fastest to slowest. Show proof of the speed and how friction affected the speed.

Formative Assessments:

Discovery Education:

can use this site to create a quiz or writing a prompt. You can check your students' progress as you go, if you group by class. You can add clips
and other Discovery Channel material.



Corkboard:

I could use this board to post reactions to stories, model how to develop a story, use a graphic organizer...

Quizlet:

http://quizlet.com/_3ijmk

This could be used for new vocabulary and review of vocabulary. Can use as flashcards.

Poll Everywhere:

Can be used to check for knowledge prior to teaching something and to check for understanding after teaching.

At least 3 done...great descriptions, links work. Great job! Let me know if I can help with anything else. - Bryan
