8th Grade Science - September/October 2018
 

Welcome to the first issue of our 8th grade science newsletter! Each month we will highlight critical content, content limits, item specifications and supports for EOC review and student success. We hope this newsletter will be useful as you and your team plan targeted, standards-based lessons for your students. Happy September!

 

FORCES & CHANGES IN MOTION


Clicking on each unit title will take you to the item specs and content limits for that standard as it pertains to the 8th Grade SSA. Clicking on the standard number (SC.6-7-8.P.#.#) will take you to the FLDOE CPALMS description for that standard.


Learning Goals
SC.6.P.13.1 (sample test item)

  1. Students will differentiate contact forces and forces that act at a distance. (Retrieval)

  2. Students will identify types of forces that act at a distance, and their properties, including electrical, magnetic, and gravitational. (Retrieval)

  3. Students will identify the different types of friction (rolling, sliding, static, and air resistance). (Retrieval)

  4. Students will identify and/or describe the role of forces acting on an object and the object’s behavior. (Comprehension)
Vocabulary
magnetic, friction, magnet, electromagnets

Featured CER (Claim Evidence Reasoning)
Apply: “What would happen if you break a permanent magnet in half?” (don’t break - just hypothesize and discuss how it creates two N-S magnets and have half the magnetic force and does so in perpetuity).

*bring up traffic induction loops, metal detectors, “free energy devices”

Featured Vernier
Probeware Lab

Middle School Manual:
#2 Exploring Magnetism – CSG, LSG, TG (Complete lab with added experiment of DC and nail coil magnet comparison) “What happens if you reverse the battery polarity?” “What other ways can you change the polarity of the magnetic field?”

LAW OF GRAVITY

Clicking on each unit title will take you to the item specs and content limits for that standard as it pertains to the 8th Grade SSA. Clicking on the standard number (SC.6-7-8.P.#.#) will take you to the FLDOE CPALMS description for that standard.


Learning Goals
SC.6.P.13.2

  1. Students will describe the relationship among distance, mass, and gravitational force between any two objects. (Retrieval)

  2. Students will differentiate between mass and weight. (Retrieval)

  3. Students will identify and/or describe the change in weight of an object as the mass OR distance of an object exerting gravitational force on it changes. (Comprehension)
Vocabulary
law, gravity, force, mass, weight

Featured CER (Claim Evidence Reasoning)
Bungee Barbies
Phase 1: Collect data with different masses and different heights.

Ultimately the challenge is to have the longest bungee cord (rubber band) to bungee from the balcony and not hit the ground (apply the math prior to dropping); known height of drop, known mass (add?), experiment to find stretch of rubber band, and use Gravitational falling force formula with mass. (without balcony, must engineer a launch pole with release mechanism)

SPEED & DIRECTION OF MOTION

Clicking on each unit title will take you to the item specs and content limits for that standard as it pertains to the 8th Grade SSA. Clicking on the standard number (SC.6-7-8.P.#.#) will take you to the FLDOE CPALMS description for that standard.


Learning Goals
SC.6.P.13.3 (sample test item)

  1. Students will describe and/or explain that an unbalanced force acting on an object changes its speed and/or direction. (Retrieval)

  2. Students will interpret and/or analyze graphs of distance and time for an object moving at a constant speed. (Comprehension)

  3. Students will identify and/or describe the role of different slopes on objects moving at a constant speed. (Comprehension)

Vocabulary
speed, displacement, velocity, inertia, motion, force, friction, acceleration

Featured CER (Claim Evidence Reasoning)
How can you demonstrate changes in motion with a balloon and straw and marble to create a Putt-Putt Golf course?

Set up: design your own course challenge that has a minimum of 2 changes in direction to reach the hole (utilizes geometry, measurement of impact force)
