This week students will be solidifying their understanding of the relationship between a line, graph, equation and table. They should be able to consider this relationship both contextualized and decontextualized and be able to answer the following:
What do graphs tell me about the relationship between two variables (bivariate data)?
What does a straight line tell me about the relationship?
What does and equation (y=mx+b) tell me about the graph of its line?
How does a table relate to a graph and equation?
We are also closing out our experience on simple machines. See beolw for more details.
Simple Machine Final Challenge Week
Throughout the last weeks you have worked with levers and pulleys and seen the impact that inclined planes can have on work. In this unit, your goals were laid out on the unit overview, and we are trying to answer the following questions:
- How do machines help us to do work in the real world?
- How are simple machines different from other machines?
- How do I know if work is being done?
- How do I decide which simple machine is right for a particular job?
- How do simple machines make work easier?
By the end of this week, you should be able to answer those questions. You will have a written assessment and a product that you create to show your understanding of these concepts.
THE PRODUCT: You will design/sketch OR build your own machine incorporating at least 3 simple machines OR research an existing machine or technology and analyze its use of simple machines. You will create one of the following:
Diagram (either of your own design or analysis of an existing machine):
___ 3 simple machines labeled
____ Written description of how your machine makes work easier.
MODEL- Build something:
___ Either take a picture or a video or bring in the product on Friday.
_____ Be able to point out the three simple machines in it
___ Be able to describe how it makes work easier
Written Explanation/Argument:
____ In a typed paragraph
____ describe the complex machine
____ the machines that it is composed of
____ how it makes work easier
I am going to BUILD DRAW WRITE.
THE WRITTEN ASSESSMENT: Multiple choice and short answer questions on energy, work and simple machines. You will be required to calculate PE and KE and solve for velocity given KE. You will also be required to calculate work given a particular situation and determine if work is being done. See your unit overview for more details.

| Goal: I can identify the simple machines (lever, inclined plane, pulley, wedge, screw, and wheel and axle) alone and within complex machines.
Goal: I can use the formula for work given a distance and force.
HW: Simple Machines Handout pg. 1 and 7 |
Goal: I can explain how different variables might affect the efficiency of a machine. I can determine when work is or is not being done on an object. I can predict which machine would have more mechanical advantage in a given situation
Have read all of Chapter 6.3 and answered all questions on pg. 147, |
Goal: Review of Potential and Kinetic Energy :Practice Questions pg 151 and 152 |
We will review the section review for chapter 6.3, Have work completed to be checked |
In Class assessment. Turn in pll practice work with final assessment. Product is due. Question: How does the amount of practice that I do affect my performance?
Product due: I can draw diagrams of simple machines and demonstrate how they could be configured to do work. |
