Game: Bohr-Rutherford Diagrams

Before class preparation

In class activity

  • If you haven’t finished the sheet in the preparation, you will be completing the sheet in class
  • Game: Bohr-Rutherford Diagrams
    • Describe patterns in the arrangements of electrons in the first 20 elements of the periodic table, using the Bohr-Rutherford model
  • Bohr-Rutherford Card Sort
  • Bohr-Rutherford Scavenger hunt

After class work

  • Check the answers for the BR-Diagram worksheet
  • Make sure you can draw a BR-Diagram for any of the 1st 20 elements with the aid of a periodic table only, you can be quizzed at any time!

Intro to Physics Experiments: Waves

Before Class Preparation:

  • Edpuzzle: Accuracy Versus Precision
  • BYOD Laptop or chromebook if you can
  • Organize the given data in a Google Sheets (Assignment in Google Classroom)
  • Read this document about instrumental error & uncertainties
  • Video: Uncertainty of a measured number

In Class Activity:

  • Lesson: Averaging raw data and its uncertainties
  • Complete Air Column Resonance Raw Data Table in Google Classroom

After Class Work:

Physical and Chemical properties

Before Class Preparation
-How do we separate chemical and physical properties and how might we distinguish chemical and physical changes in substances?
-Would a change of state (e.g. solid to liquid) be a physical or chemical change?

In Class Activity
-Identifying physical and chemical changes
-Alka-Seltzer demo
-Instant snow revisit

After Class Work
-Chemical and physical change card sort

Resonance in an air column

Before Class Preparation:

  • Read this overview of Resonance in an Air Column
  • Answer Pre-Lab Questions in Google Classroom (due before class)
  • What is the distance between different parts of a standing wave (nodes, anti-node) in terms of wavelength?
  • Read this handout: Air Column Resonance
    • Print if possible
    • Identify the variables on the handout
    • We’ll be working with water, so computers are not a good idea
  • Download frequency apps:

In Class Activity:

  • What is the goal in a science experiment?
  • Resonance of standing waves
  • Resonance in an air column
  • Verifying the speed of sound in air
  • Record your results here

After Class Work:

Physical Properties: Density

Before class preparation

  • How would you identify unknown objects (elements?)
  • Read over the Density Calculations worksheet, print if possible
  • Is density a physical or chemical property? Why?

In class activity

  • Density Demo & Explanation
  • Coke vs. Diet Coke
  • “Smart Meter”
  • Density Calculations (Sage & Scribe)
  • Collected next class

After class work

Quiz – Waves

Before Class Preparation:

  • Finish Assigned CK12 & Self Quizzes in Google Classroom

Can you:

  • State the wavelength, amplitude, equilibrium point, frequency of a wave
  • Solve problems involving the wave equation v=fλ
  • Use the principle of superposition and draw a graph to represent interference of waves

In Class Work:

  • 15 minute pre-quiz discussion
  • 15 minute quiz

After quiz:

Take up the quiz immediately using Sage & Scribe 

Lab: Density

Before class preparation

  • Read and Print this document
  • Predict and Explain your hypothesis on the document
  • Design a table to record your observations according to instructions in the document

In class activity

  • Investigate, through inquiry, the physical property of a common compound (water)
    • What happens to the density of water as the volume increases? (40 minutes)

After class work

  • Complete the hypothesis section of your good copy
  • Draw an iceberg and see how it will float.
  • Bring an empty recyclable water bottle and a ketchup packet if you can
