Tuesday, October 24, 2017 Day 3

Homeroom:

  • Turn in Magazine Drive Orders!

Grade 8 Agenda:

Design an experiment to explore the field between two electric charges.

Your assignment is to identify a scientific question that can be investigated using the PhET Charges and Fields simulation.  Your investigation must involve exploring the electric field between two charges.  After you identify a valid scientific question, you must:

  1. identify the manipulated, responding, and controlled variables in the experiment.
  2. write a method for conduction your investigation.
  3. prepare suitable data tables for recording data.
  4. collect and record data.
  5. prepare a graph showing your results.
  6. prepare a report that presents your results and answers your experimental question with suitable evidence in support of your conclusion.

Use the PhET Charges and Fields simulation.

Review notes and check definitions of terms on this list.  

This will be a graded project - you must demonstrate the following:

  • ability to write a scientific question

  • correct identification and use of manipulated, responding, and controlled variables.

  • good practice for collecting and organizing data

  • graphing ability

  • preparation of a neat, professional report

  • making a valid conclusion with appropriate support

Report requirements will be provided Thursday.

Final report will be due Monday.

Some class time will be provided - including tomorrow.

WIN:

Study hall and conference Time.

Source credibility - continued work

Grade 7 Agenda:

Homework:

  • Calculating Density worksheet - use FDSS method, due Thursday

  • An assignment will be given in class tomorrow - do not put this off...

  • Quiz Make-ups will be given in class tomorrow

 

SLANT: DENSITY

  • PHYSICAL PROPERTY

    • defined: how much matter is packed into a certain volume

    • DENSITY DEMONSTRATED

    • determines Buoyancy

  • DIFFERENT FOR EACH ELEMENT/COMPOUND (UNLESS SAME BY COINCIDENCE)

  • RATIO BETWEEN MASS AND VOLUME

    • WHAT IS A RATIO?

      • fraction
      • comparison of two quantities
      • how much of one fits in the other
  • EQUATION DENSITY=MASS / VOLUME

  • MASS

    • units: g
  • VOLUME

    • units: mL and cm3
  • SOLVING A PROBLEM: FDSS FORMAT

  • Practice
