All students should be rereading chapter 1, in anticipation of a review of Motion

Mousetrap race car rules and requirements packet.

Today's Lateral Thinking question:

Sid Shady is in jail and is planning his escape. His cell, which is on the third floor, is 30 meters above the ground level. Shady managed to remove one of the bars from the window, enabling him to squeeze through. He has a rope, but it's only 15 meters in length and a fall of 15 meters is too dangerous. Aside from the bars on his cell window, there is nothing else above or below, where he could attach the rope. However, using just the rope Shady managed to escape safely. How?

Today's Class:

Students began their mousetrap races on Thursday and Friday and we will continue this today. Students will create graphs using Excel on the laptops to graph the motion of the class cars. (Students who did not make a care can use this as a second chance to pull out some type of grade rather than taking a zero on the project.) We have finished up our races and students will now work on building a speed and time graph using Excel. All students need to remember that they can only graph cars that traveled at least 4 meteres to maintain accuracy and precision in their data. After completing the graphs we will look at two different virtual labs designed to reinforce the information in this unit
Ticket out the door- Describe at least three forces acting upon your mousetrap car.

Today's homework:

Watch the videos listed above. By Friday of this week you should have viewed all three videos.
Unit Vocabulary
speed, velocity, positive acceleration, negative acceleration, inertia, momentum, contact forces (friction), non-contact forces (gravity, electrical and magnetic) balanced forces, unbalanced forces, net forces, Law of Universal Gravitation, mass, weight.
