Bell work – Explain how yesterdays lab shows Newton’s 2nd Law.

We graded bell work notebooks for the following assignments. These were all done in class.

  • 1st law activity
  • 1st law cheat sheet
  • mass lab (cars)
  • acceleration lab
  • Bell work 8/27 – 9/7

Vocabulary -Define the following words

  • Friction
  • balanced force
  • Unbalanced force
  • mass
  • acceleration
  • force
  • Newton’s 1st law
  • Newton’s 2nd law
  • Newton’s 3rd law
  • weight
  • motion
  • velocity

8th grade

Bell work – List each type of atom present and how many of each present.

  • H2O

We graded bell work notebooks for the following

  • Static (balloon) lab
  • Atomic structure – draw 7 atoms and their parts
  • Atomic model checklist
  • Model comparison
  • Bell Work 8/27 -9/7

Counting atoms worksheet.

Counting Atoms

September 6

7th Grade

  • Bell work – Give 2 examples of unbalanced forces.
  • Finished Acceleration lab.
  • Acceleration lab

8th Grade

  • Bell work – Explain why the “modern” model of the atom is the most correct.

September 5

7th Grade

  • Bell work- Define balanced and unbalanced force.
  • Acceleration lab
  • Acceleration lab

8th Grade

Bell work -Why is it important to understand the number of protons, neutrons and electrons in an atom?

Look up the following atomic models on the internet. Using the “Atomic Model Checklist” from Tuesday, create a T chart for each model showing the pros and cons for that model based on how it compares to the checklist.

  • Dalton
  • Thomson
  • Rutherford
  • Bohr
  • Cloud
  • Modern

September 4

7th Grade

  • Bell work – Define independent variable and dependent variable.
  • Finished Mass Lab

8th Grade

  • Bell work – Draw and label a square from the periodic table
  • Wrote down “Atomic Model Checklist” in our notebooks.

To be a good representation of an atom a model show the following.

  1. All 3 sub atomic particles and their charges.
  2. Protons and Neutrons should be shown larger than electrons.
  3. Protons and neutrons should be close together in the center of the atom.
  4. Electrons should be smaller than protons and neutrons, should be far away from the nucleus. They should be in an area around the nucleus.
  5. The atom should show its structure is mostly empty space.
