To Do: 15 minutes to work… Turn in October Sky Lab Write-up (regular sci) Grab a yellow lab sheet and answer all analysis questions from Physics 500 in your journal using complete sentences. Read pages 3-6 in our new book  Vehicles in Motion Create a new journal entry called “Motion Brainstorm” and answer the questions on pages 5 & 6 in complete sentences and be prepared to discuss your answers with the class. Begin to develop your own definition of motion. o How would you describe motion to a third grader?

While Messing About: Copy the table below into you journal on 4 separate pages One page for each of four toy cars you will be examining Be sure to record which toy car you are examining Refer to pages 8-9 for descriptions of each category. Also include a sketch of the top and bottom of each toy car that you examine on each page below your chart. Toy Car: _________________ Structure Mechanisms/Parts Performance

To-Do List (Day 2): 1.Get a book and think about the questions on page 10. Consider how your answers to these questions have changed since last class. Add any new thoughts to your “Motion Brainstorm” journal entry from last class. 2.Create a new physics project board on the next five pages of your journal using pg 11 in the book as your guide. Don’t forget the big challenge question! 3.Reflect on the last week of science class and add a few things to the first three pages of your project board. 4.Grab an equation chart handout from the side counter and cut & paste it to your journal (see example on front table)…update your table of contents 5.If you finish all of the above, read pages 21 and 22 in your book

Set up project board Design and build a vehicle that will go straight, far, and fast, and carry a load What do we think we know? What do we need to investigate?

Project board What are we learning?What is our evidence?

Project board What does it mean for the challenge?

Think, Pair, Share… After a solo reflection on the items below, discuss the following with your table groups: - What did you learn from messing about with the toy cars? - What did you notice/discover about each car? Hot Wheels Pull Back Cars Speed Racers Battle Tanks Be prepared to share out as a class  Stand Up Review!

Give 1 Take 1… Goal: Mingle with peers who you wouldn’t consider to be your closest friends in order to add new things to your project board. Rule: You must give them one new idea to add to their project board that they do not currently have listed and you must take one new idea from their project board that you don’t have yet. If neither person has any new ideas, then you must create a new idea together!

Relative Motion Reading Goal: After reading pg 21-22, have a class discussion to explain relative motion and frame of reference. Key Question: Is the bowling pin on my desk moving? Explain. Train Car Example:

Relative Motion Reading

Frame of Reference Relative motion is just a way of saying that sometimes different people will say different things about the motion of the same object. Relative motion is just a way of saying that sometimes different people will say different things about the motion of the same object. This is not because one of them is wrong, but because they are using different frames of reference. This is not because one of them is wrong, but because they are using different frames of reference. The best way to see how this is possible is to look at some examples. The best way to see how this is possible is to look at some examples. In all of the following examples, ignore air resistance. In all of the following examples, ignore air resistance.

Did YOU know? Frames of reference and relative motion is actually the reason that people get car sick. Your brain is getting two different sets of information about your body's motion that might not exactly agree with each other; information from your eyes, and information from your inner ear. Some people are more sensitive to these differences, which causes them to feel car sick as they watch the road "whiz" by. If you are prone to getting car sickness, try to look forward at a point far in the distance and stay focused on that.

Equation Chart  SPEED! Can you create a line in your new equation chart for speed? ???

Sept 12, 2003Astronomy 100 Fall 2003 Speed or Velocity What’s the difference between speed and velocity? Measured in km/h, miles/hr, cm/s, AU/century, etc…

3/13/ Average Speed Your instantaneous speed, difficult to measure, is your moment-to-moment speed Your instantaneous speed, difficult to measure, is your moment-to-moment speed Your average speed is the calculated measure of your speed over a distance. Your average speed is the calculated measure of your speed over a distance.

Sept 12, 2003Astronomy 100 Fall 2003 Average Speed You notice when you drive you can never keep a constant speed due to stop signs, traffic, whatever… Your instanteous speed is what your speedometer reads.

Sept 12, 2003Astronomy 100 Fall 2003 Speed or Velocity We use the terms loosely today, but there is a distinction. Velocity is a speed AND direction. See the arrow?

Sept 12, 2003Astronomy 100 Fall 2003 Speed and Velocity Take as an example, a car driving in a circle. The car is always going the same speed, but it’s direction, or velocity, is constantly changing. From Conceptual Physics
