19. 9/26 Turn in your worksheet from yesterday if you did not do so already. Answer this question in complete sentences. – What makes boats float???

20. Expectations for Groups Remain seated with your group Work quietly Compromise, work together and get along No horseplay If you need something, raise your hand

21. 9/27 Try to list as many of the different types of forces as you can by memory. Then, look at your list and see which ones you didn’t remember and write those down as well.

22. 9/28 Get our your data sheet from yesterday so we can discuss it Opener: – What different things could possible affect the speed of your boat? List as many as you can think of.

23. 10/1 Do not turn your homework in today. Have your homework out so that I can check it. Opener: According to Newton’s 1 st Law, objects with greater mass have more inertia. What does this mean for your sailboats?

24. 10/2 Turn in your worksheet from yesterday if you took it home for homework. Opener: 1.An object with a mass of 10 kg is pushed with a force of 2 N. Calculate the acceleration that will happen. 2.If the object has a mass of 20 kg, what will the acceleration be?

25. 10/3 Please turn in your Newton’s 3 rd Law Packet from yesterday. Opener: – How are the formulas for weight and force similar? How are they different? Weight: Fg = mg Force:F = ma

26. 10/4 Turn in your study guide Check the list of things you should have turned in on the front board. You have 5 minutes to study to prepare for your benchmark

27. 10/5 Turn in your “Friction Reader” from yesterday if you did not do so already Opener: – What is friction and how does it affect the motion of your sailboat?

28. 10/8 Opener: Please reflect on the quote on the wall. Write a 5 sentence reflection. What does this mean? How does it relate to school / your life?

29. 10/9 Make sure you have turned in your “Newton’s 3 rd Law” packet and your “Friction Reader.” Many of you are missing these assignments! Opener: – How do friction and applied force compare to each other when the boat is moving at a constant speed? Are they balanced or unbalanced? Why?

30. 10/10 Winners of 2 nd Round of Testing: – Deshawn, Yuri, Keonte, Arthur (3 rd period) – Nya, Mynish, Shariah (4 th period) What is creativity? How creative was your design? Why is creativity important?

31. 10/11 No opener today Please get your binder and have a seat. We will be going to the computer lab as soon as everyone is settled. Turn in your Vocab Review Worksheet. It is due today. If you would like to take your boat home, come get it at the end of the day. Otherwise, they will be recycled.

32. 10/12/12 Please make sure you have turned in your Vocab Review Worksheet and your Sailboat Test Data Sheet 2 Vocab quiz will be first today (before lunch for 3 rd period) You have 10 minutes to study

33. 10/15/12 Opener: – John is riding in a go cart. He is holding an ice cream cone piled high with scoops. When he makes a sharp right turn, what happens to the scoops of ice cream? Which of Newton’s Laws explains why? Please be sure to sharpen your pencil before our quiz today.

34. Opener – 10/17 If an object starts at position 4 and ends at position 10, what is its displacement? ∆x = xf – xi ∆x = displacement xf = ending point xi = starting point

35. Notes – 10/17 The first way to measure motion or movement is called displacement – Displacement is how far an object is from where it started – It is different from distance because it also tells you the direction something went – Positive number = forward direction – Negative number = backwards direction ∆x = xf – xi ∆x = displacement xf = ending point xi = starting point

36. Opener – 10/18 Do you think the inventors of the roller coaster were white or black? Why do you think so? Does the fact that Mr. Wurz is white affect the way you view this class?

37. Reflection Reflect on the video you just saw. Underneath your opener for today, please write down your reflection on the video you just saw. What are your thoughts and feelings?

38. Opener – 10/19 A girl is hanging from a rope. The force of gravity acting on her is 200 Newtons. If all the forces acting on her are balanced and the net force is 0, what is the force of tension in the rope pulling her up? Draw a diagram of these two forces acting on her and show that the net force is 0.
