3: Newton's First Law of Motion - Inertia

Pace: 5 Days
Checkpoint:  XXX


Big Ideas

Standards

P3.2 Net Forces
Forces have magnitude and direction.The net force on an object is the sum of all the forces acting on the object. Objects change their speed and/or direction only when a net force is applied. If the net force on an object is zero, there is no change in motion (Newton’s First Law). 
MS-PS2-4.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects. [Clarification Statement: Examples of evidence for arguments could include data generated from simulations or digital tools; and charts displaying mass, strength of interaction, distance from the Sun, and orbital periods of objects within the solar system.] [Assessment Boundary: Assessment does not include Newton’s Law of Gravitation or Kepler’s Laws.]

3 Pretest and Student Differentiation

If you score a 90% or above on this pretest on your first attempt you will not need to complete any of the practice for this unit and an accelerated assignment will be provided.  The pretest is not open internet or buddy or book.  This pretest will be timed and may only be completed in class.

#1 

EXPLAIN IN YOUR NOTEBOOK:
1.  Watch the Demos.  With your group explain what is happening with an explaination in your lab notebook.   

7 Inertia Demos



REFLECT IN YOUR NOTEBOOK:
2.  Watch the following "What is inertia" video and complete a 5 sentence reflection WITH at least ONE diagram describing the main idea.  

What is Inertia?


Extra Credit:
Create your own misconception video about Inertia and submit

Below is a list of possible misconceptions to explore in your video

#2 
3.4 Newton's Law of Inertia
pg 33-34

BIG IDEA:
Newton’s first law states that every object continues in a state of rest, or of uniform speed in a straight line, unless acted on by a nonzero net force.
Day 2 PRACTICE:

BOOK NOTES:
1.  Use the key terms and your text to complete Cornell Notes for this section.  Include diagrams and examples as much as possible.  
KEY TERMS:
Newton's First Law
Law of Inertia
Net Force
Friction 
Inertia


CREATE:
2.Create a mini lesson on the topic of Newton's first law.  Your lesson should include all KEY TERMS that are EXPLAINED with an EXAMPLE. You should be able to share your information in some way (video, website, poster, etc.) and last now more than 4 minutes.  Use this one of the following videos   as an example.
Example #1
Example #2

#3
​
3.5 Mass - A Measure of Inertia
3.6 The Moving Earth Again
pg 36-39

BIG IDEA:
The more mass an object has, the greater its inertia and the more force it takes to change its state of motion.

The law of inertia states that objects in motion remain in motion if no unbalanced forces act on them
BOOK NOTES:
1.  Use the key terms to create notes about the big idea.  
KEY TERMS:
-Mass
-Weight
-Kilogram
-Newton
-10 Newtons in 1 Kilogram
VIDEO REFLECTION
2.  Review the following "The Difference b/t Mass and Weight" video and complete a 5 sentence video reflection WITH at least ONE diagram describing the main idea.  
PAPER PRACTICE:
3. Complete the following practice.

DAY 3-4: 3-4 October
3. Inertia Labs and Practice

You must read, consider, and attempt each problem, as you do not know which problem your group will present.  Record your thoughts for each lab in your journal
inertia Labs

DAY 4: 4 October
3.Review

Use the following materials along with your materials from Chapter 3 to review for your Chapter 3 Mastery Check.

This review will help you prepare for the final assessment but will not be included in Power School.
