LEARNING AT HOME (HW)

Exam Thursday. Review Days 100-116

Essential Question: How can energy be transferred?

GOALS: SWBAT...

1. list the requirements for the Rube Goldberg project

2. Assess their current knowledge of simple machines

3. Define "machine", and the six types of simple machines

4. Compare and Contrast the three classes of levers

I'll be checking today's assignment for credit on Monday, at the beginning of class. You should complete today's assignment in class. Make sure Mr. Potkin signs off on your completed work (in your notebook) before the end of class. Also, there's extra credit available. See the HW section for info. Questions? Get permission to use your phone, then message me via the Remind App. 

Best,

Mr. Alexander

WARM-UP 117 (4 min)

1. list three concepts you'll need to understand in order to be successful with this project

2. which component of the project am I valuing the most in assessing your learning (aka, in assigning your grade)

3. list two ways you can earn points (aka, show knowledge)

4. list two ways you can lose points (aka, show lack of knowledge)

CLASSWORK

1. 117A: Simple Machines Knowledge Inventory (15 minutes)

This is just like the knowledge inventory we did for Thermodynamics. We'll do the pre-learning now, and the post-learning at the end of the unit. 

Make a four column organizer with the following columns (see below in ORANGE, or day 101 in your notes for an example)

This will take about 1-1.5 pages. 

Number, copy, and answer the questions below in your organizer

Rank your current understanding of each concept, from 1 (low) to 10 (high)

Remember, don't look up the terms or questions for the knowledge inventory. We what to know what YOU know.

  etc.....

QUESTIONS: 

117B: The Six Simple Machines (15 minutes)

Below, I've provided two links to informational pages on simple machines. Use both to improve your understanding of simple machines. 

1. Define the term, "machine"

2. Create a graphic organizer like the one below. Use it to define each of the six simple machines

Great definitions of five of the six simple machines. https://www.explainthatstuff.com/toolsmachines.html

Good for examples and alternate definitions of machines. Includes a good definition of 'inclined plane' that isn't in the first link: http://idahoptv.org/sciencetrek/topics/simple_machines/facts.cfm

117C: Venn Diagram: Three Classes of Levers (10 minutes)

In case you're wondering what "class" means, a synonym for class is "type", or "kind of". So, "Three Types of Levers".

Use the resource linked below to read about levers, and to create a three-ring Venn Diagram comparing and contrasting the three classes of levers. 

To fill in your diagram, think about definitions, examples of each lever class, and functions of each class. 

LINK: https://www.explainthatstuff.com/toolsmachines.html (the notes on lever classes are titled: "Types of lever", and are approximately 1/4 of the way down the page) 

    

LEARNING AT HOME (HW)

1. Complete any incomplete classwork from today

2. Complete any late assignments (states of matter lab)

3. EXTRA CREDIT OPPORTUNITY: 

Want some? Our Rube Goldberg project is materials heavy, so, if you'd like to donate some common materials to class, I will reward your support with points.

Things which are larger, or more expensive (boxes, glue sticks, springs) will get more points per item than something small and cheap (10 straws, for example)

Here's what we need, preferably on Monday (03/18/19):
