Physical Science Week of 10/9-10/13


FYI: All students will take the PSAT 8/9 on Wednesday, 10/18, starting promptly at 9:15. Due to the College Board return procedures, there will be no make-up testing for this test, so please ensure your student is present on testing day. Contact Joni Myler if you have any questions: [email protected] 


Thursday and Friday:


Reminder: PBL’s are DUE on Monday 10/16 at the END of the period. (I have reserved the laptop carts, HOWEVER be mindful that we have early release. There will only be approx. 30 minutes per class.)

Here is the template: Business Proposal Template OL 14-15-23fhj9t

Some Helpful Information for you to use when writing your PBL:


  1. ICE CREAM LAB DAY!!!!! (Thank you Hovarth Family for sending in plastic spoons! It was so appreciated!)
  2.  Here is a copy of the lab Dry Ice vs Water Ice Lab OL – Student Format 17-psj31z
  3. LABS ARE DUE ON FRIDAY 10/13!!!


Monday 10/9 and Tuesday 10/10:

Class Agenda

Today we worked on PARTICLE DRAWINGS for the 3 types of heat transfer. Conduction / Convection / Radiation

Here were the directions and information given to each student:


You are to create 3 diagrams showing each of the three types of heat transfer as it pertains to your ice cream. (conduction, convection, & radiation)

Use paper that is 8 ½ X 11 inches only.


  • dry ice temp is -78.5°C
  • ice cream is at -13°C when it is put in the ice cream cart
  • the water ice is at 0°C
  • air temperature is 30°C
  • heat transfer goes from the warmer substance to the cooler substance


Your diagrams should show what is happening with the particles as the energy moves from one substance to the other.  It should be obvious what is happening to the particles as the heat transfer occurs. Include arrows to show the direction that the particles are moving and/or energy is being transferred. To clarify your diagrams, add captions as necessary.   Be sure it is clear why the particles are moving and/or the energy is transferring in your drawing or captions.  You may NOT use images of these events from the Internet.

You need to have one page for conduction, another page for convection and another page for radiation.

***Remember, these will be part of your proposal and should be a quality that will impress the CTO!!***

Physical Science Week of 9/18-9/22



Today in class we worked on Particle Drawings for the 4 States of Matter.

Here is the paper if you missed class: (This is important because you will hand in your particle drawings with your Business Proposal at the end of the PBL.) States of Matter Diagrams 13-21lpeix



Today students began their research on our next PBL. We will be looking at the 4 States of Matter.

  1. Take NOTES…. Include the following vocab terms: states of matter, solid, liquid, surface tension, viscosity, gas, atoms, molecules, crystalline, amorphous (these words are within the reading in Italics… look carefully.)
  2. Take notes on the states of Matter. LIQUID, SOLID, GAS, PLASMA. Be sure to include: particle position, motion/speed, volume and shape.
  3.  Don’t understand PLASMA? Here is a good overview:


Research for PBL for unit 4

  1. Measure the temperature of your freezer.
  2. Place a scoop of ice cream (from your freezer) into a bowl and measure the temperature of the center of the ice cream scoop. (If you need to use sorbet or almond milk ice cream etc; please do)
  3. Eat all of the ice cream except for one spoonful. Measure the temperature of the last spoonful.
  4. Describe the consistency of the ice cream as it first came out of the freezer, and of the last bite.




Today we introduced ourselves to our Unit 4 PBL!

Melting ice cream problem PBL Statement OL-1lhln6u



All students were given the opportunity to re-write their Chemistry in a Bag Lab from 9/8.

Here is the Rubric for the grading and some tips for writing in the CER method.


10 pts

Clearly stated                           10 pts

Unclear                                        5 pts

Missing or unrelated                  0 pts




40 pts


Specific color change                10 pts

Temp changes (up & down)     20 pts

Gas production                           10pts



50 pts

Restatement of claim w/ supported, refuted or inconclusive                                                     10 pts

Summarized all evidence collected:  color change, temp changes, gas production                 15 pts


Evidence suggests statement                                                                                                              10 pts


Connection of scientific fact                                                                                                                15 pts


CLAIM: (10) Do not use “I” or “our” A claim is a simple 1 sentence statement. However, be sure you are specific. (Especially if you are using chemicals)

EVIDENCE: (40) Be sure to follow the ORDER of the lab. It does not make sense when you are just jotting random things down. Also, be sure to write the chemicals you are using “BB” makes no sense.

REASONING: (50) There should be no “I” or we” Be sure that you have re-stated your claim and said if it was supported or refuted. Summarize your evidence in paragraph form.  “The data suggests a chemical change occurred because…” CONNECT TO A SCIENTIFIC FACT (Use the info GIVEN to you on the back of the lab)

DO YOU NEED THIS LAB?  Chemistry in a Ziploc Bag OL 2016-26oxtm2

CHEMICAL NOTES SHEET_ziploc bag lab-uxzx0h


Class Agenda:

  1. Students were given the entire class period to work on their PBL Banana Poster.
  2.  Please see my previous post on FRIDAY 9/15 for the powerpoint, rubric and requirements for the PBL poster or pamphlet.
  3.  ALL Banana PBL posters are due tomorrow. 10 points off per day for late submissions unless there was an absence.
  4. TOMORROW– I am holding an AMNESTY DAY in Science. Many, many students need to fix, or re-do C.E.R labs that they have handed in. Tomorrow will be a day to re-do and improve their LAB grades. Students are not using their time wisely or their resources to write their labs, therefore I am allowing this class day of work time to improve their Lab averages. Please come prepared to work independently.
