MS-PS1-2. Analyze and interpret data on the properties of substances [before and after the substances interact to determine if a chemical reaction has occurred].
 
SEP: Scientific Knowledge is Based on Empirical Evidence:
Science knowledge is based upon logical and conceptual connections between evidence and explanations.
 
SEP: Analyzing and Interpreting Data
 
CCC: Patterns
Today in Class:
1.  You should have first listed a reading strategy as you copied your homework.
2.  Next, you and your group read the Essential Questions and the Performance Standards and you answered these – relating them to the work you completed with your experiment.  You should have written this information on your Box Paper (practice lab).  
3.  Then, you and your partner met and really discussed and finalized your written lab work– you should have been able to complete your final Experiment Title, the Problem statement, your Hypothesis, Materials List,  Procedure, Improvements made, ….   You may have a few lines to write or need to double-check your Data Table / Graph / Chart.  You will have 5+ minutes to complete the final details on this tomorrow.
4.  I evaluated some of the details on your data chart /graph / table….. to help you make those final changes as you were working.
Homework:  Read “Atoms and Elements,” pages 7-12.  This is assigned on Google Classroom.

CCC: Patterns
Today in Class:
1.  Explained that students need to complete any missing HW this long weekend.  Next week– all missing HW is due for the TRimester.
2.  Partners double-checked the organization of their graph/ data table/ chart … many of you had forgotten what a Control Experiment or what an (Independent) Variable is.  I aske you to look this up in your notes — if you have lost this information, I am pasting a link below… You DID learn this with Mr. Piccard and Mrs. Slotman last  year, I I have also reviewed this earlier this year for a couple of the labs / experiments.  
3.  Once you set up your data table or graph, with labels, you were to set up your Control Experiment and make your Golf Ball sink!  Most of you completed this task right away.  You recorded this data and then moved on to the next experiment.
4.  Now, most groups needed to run multiple trials – for their (Independent) Variable experiments.  After you and your partner ran a few trials, most of you were able to get that Crazy golf ball to float.!  Great job!  Nice determination and persistence!  You again recorded this data and then cleaned up your area.
5.  Some groups did not complete their Variable experiments.  If  you and your partner wish to come in Monday morning and run one or two more trials,  I will have my door open for you between 7:20 and 7:25am.
You will be writing up your final lab report Monday!  You should be ready!
Take-Away Task — Homework:   1.  Complete  any missing work.  2.  Study your Chemistry notes.    3.  Your practice graph / data table / chart should have been completed in class today.  If it was not, complete this!

Today in Class:
1.  Phenomena:  Chemical Crime Solvers: Students listen to a story about a forensics and firefighting team, and how they had to use various chemical and physical properties to determine  how the fire started. 

After, students checked to see how many C & P properties they identified.  

2.  Partners decide how they will mimic the golf ball/tennis ball container demonstration. They Ask, Imagine, & Plan (STEM Engineering Process), and write their plans on a Lab WS – experiment will be completed tomorrow during class.
Hypothesis
Materials
Procedure
Physical Properties – concepts
Chart / Table / Graph (to record data)

3.  Most teams of students completed all of the above sections of the STEM paper during class today.  You  also should have listed in your Planner and on your STEM paper the material(s)  you hope to bring tomorrow to class to complete this experiment. 

 

Take -Away Task ~~~  Homework:  Bring your  material(s) that is/ are needed for the experiment tomorrow.

Performance Standards/ Disciplinary Core Ideas / Science & Engineering Practices:

MS-PS1.A     Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. 
(MS-PS1-2),  (MS-PS1-3)

MS-PS1-2. Analyze and interpret data on the properties of substances [before and after the substances interact to determine if a chemical reaction has occurred].

CCC: Scientific relationships can be represented through the use of algebraic expressions and equations.

SEP: Analyzing and Interpreting Data

 

Today in Class:

1.  Phenomena:  Observe, Wonder, & Infer:  Use physical properties to describe the 3 powders on your table.  Next, ask questions about the powders,  involving possible chemical properties that would help you to identify these powders.  Lastly, write a hypothesis, an inference as to how you would prove the identity of one of the powders.

2.  You completed an in-class assignment— Chemical and Physical Properties #2.  You were able to refer to notes and reading strategies as you noted specific physical and chemical properties that were good identifying characteristics of these substances.  We then discussed and corrected these Q & A.s.  

3.   Last, we discussed our class results for “I Love Density.”   You should have been able to explain which liquids were the most / least dense, as well as used the table to compare the densities of different liquids for the numbers on the tables.  I explained how the molecular arrangement changes from more dense to less dense substances. 

 

Homework:  Study Chemistry Notes: Chemical and Physical Properties, Metric Measurement….  use the Study Game method….make sure to study out loud.!

Today in Class: 

1.   Students began by answering and asking questions about the performance standards, and noted how they thought these standards would relate to the class procedures this week.

2.  I discussed the effort (or lack thereof) on the recent assignment, especially worksheet p. 6-7.  Too many students did not read the directions or paragraphs on the pages before answering the questions.  Other students did not refer to their Graphic Organizer notes (Chemical and Physical Properties).  You students are super-talented and intelligent– and this was an easier level worksheet to check on your introductory level understanding of these properties.  I asked you to slow down and think about the reasons why you did not (or did) score higher on this worksheet.  I also offered a Make-Up worksheet for this assignment.

3.  I Love Density!!!  (So do you!!)  You searched for and then we  shared with the class how to determine density of a liquid using algebra  and simple math.  I determined the density of molasses with the class, and then each group of students determined the density of a different liquid.  Each group completed the math necessary and then reported their results, which were put into a Google.sheets document.  Most of the students completed the class results on this Data Table  (If you need to check your data, you will be able to tomorrow during the beginning of class). 

 

Homework – Take-Away Task:  1. Complete any missing assignments or Make-Up assignments that you need to do.  2.  Study your Chemical and Physical Properties, & Measurement Notes.

MS-PS1.A     Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.               (MS-PS1-2), (MS-PS1-3)

***Which characteristic properties (chemical and physical) can you use to identify any particular substances?

***How will  you  analyze and interpret data on the properties of the substance?SEP  Analyze displays of data to identify linear and nonlinear relationships

 

Today in Class:

1.   We talked (in most classes) about the importance of writing sentences to explain information related to your experiments on your lab worksheets.  About 85-90% of the class needs to improve on this area.  The nice thing is that your English / LA teachers are working with me to encourage you to improve with this skill.

2.  You cut out heart shapes, yes, heart shapes!  Why???  Because you LOVE density!!!  If you do not yet understand why you LOVE density, don’t worry, it will become clear tomorrow.    We will be completing a Density experiment tomorrow—  this love of density is key to understanding how to determine density!

3.  Notes:  Measurement notes….  you learned about the description and definitions of types of matter, the tools we use to make these measurements,  the metric units to describe the amounts measured…. and you saw the different tools and examples of measurement – taking.  (these will be updated on my Blog directly after this post)

 

Take-Away Task ~~ Homework:    Can you make a column of liquids as shown to you during class?  You may use a plastic glass or regular glassware (I know you don’t have a graduated cylinder at home!)   Make sure to ask a parent for permission to use a glass and any liquids– you choice.    If you do this activity, either draw a diagram of the results (and label) or take a photo (save on your Google.drive).  We will talk about the results you have brought in to class tomorrow.
