Make-Up Test and last New Unit

If you need to take a make-up test or RE-test for Acids, Bases, and Solutions, you can either plan to 1) take it during your study skills period OR 2) take it after school Thursday 5/2, Friday 5/3 or Wednesday 5/8. I have meeting after school on Monday and Tuesday next week.

Remember that our Lab Write-up for Titrations will be due THURSDAY 5/2. Please see the previous post for a Word Doc helping you to complete this Lab write-up. The questions for Kinetic Molecular Theory are due at the beginning of the period on Thursday 5/2 as well. You had time to complete most, if not all, of this in class on Tuesday.

Our last unit for the school year will cover Gas Laws and Equilibrium. I have scheduled the TEST for Thursday May 16th. You will have a TWO webassigns for this unit 1) Ideal Gas Law and Conversions due Friday May 10th before midnight and 2) Equilibrium due Tuesday May 14th before midnight.

Lab Report, Make Up Lab and Webassign

The Webassign on pH and titrations is due tonight (Friday April 26th) before midnight! Our Test is Tues 4/30. Test flashcards are located in an earlier post. Scroll down to an earlier date for that.

Of you were absent from school on Friday April 26th and missed the Lab, you must do a make-up assignment. Here is the “virtual” titration lab link that can be used with handout provided in class.

Here are my thoughts on the Lab write you should be turning in on Tuesday April 30th

Important Reminders!

Tomorrow (Friday April 26th) is our Titration Lab and the pH Webassign is due before midnight! Don’t forget to wear Not-your-nicest clothes (Keith, I will give you time to change) as we will be working with strong acids and strong bases. Also-Our Test for Solutions and Acids will be next Tuesday so please begin to study. Remember that the flashcards that Curran typed up are in an earlier post. Just scroll down to access those, or MAKE THEM for extra credit!

Webassign due Friday April 12th

Flashcards updated below on 4/12

Our new unit is on Solutions, Acids, and Bases. I have scheduled 2 webassigns for this unit. Molarity and Dilutions will be due this coming Friday April 12 before midnight. The pH and Titrations webassign will be due Friday April 26th before midnight. Both of these due dates are A-Days so I will remind you about the deadline in class and via this website post.

The projected due date for the test of Solutions, Acids, and Bases is April 30th

Here are the Test Flashcards that you can use to study or make for extra credit.

Upcoming Test and last unit for the year!

Your Astronomy TEST will be Tuesday April 9th! Flashcards for this test are in the previous post. As usual, you can make these for extra credit if you bring the to class on test day. Our last unit for the year will be about Human Impact on the Environment.

26% of the Exam questions will come from this one unit!  We saved it for last hoping you will remember much of the information that we study in April and May.  I have several links I want to provide for your use and study.

Here is the Flashcards Word doc for Human Impact Unit. You can make these for extra credit as always.

Here is the link to the You Tube for “The Story of Stuff.” We will watch this in class and consider the problem and possible solutions. A handout will be provided for this activity.

Here are the website links for a investigation in to creating a Zero Carbon Footprint. We will calculate our carbon footprint and then investigate things that are being done around the world to mitigate the problem,

Webassign and Heat TEST

The Heat Webassign is due tonight! (Wednesday April 3rd before midnight). All the problems are Q=mCp delta T. Recall that heat lost is exothermic. In #3 letter b, when they say the heat is lost, you do not need to insert a negative sign. The correct answer for webassign will be positive.

Your Chapter Test on Heat, Reaction Coordinate Diagrams (Potential Energy Diagrams), and Phase Diagrams is THURSDAY April 4th. Flashcards for this test are posted as a link to a Word Doc in the previous post.

The Solutions Dissolving Process Study Guide on pages 4, 5, and 6 of your new packet will be due on Monday April 8th.

Under this calculation, show the work for the % Yield and % error for this experiment.

Turn in your Lab handout with this data and please attach these instructions so I know how to check your work.

Reminder to STUDY!

Stoichiometry Quest Friday March 8th (50 points, equations are provided and balanced) and the Stoichiometry Webassign is due before midnight Friday night. We are on an early release schedule so Be ready!

Stoichiometry

Our Stoichiometry “Quest” (little test big quiz) will be Friday March 8th. That is an early release day so the classes will be one hour in length. Since this is less than 10 problems, we should be able to finish the “quest” in the shortened class period. Here is a tutorial that might help with mass-to-mass stoichiometry

Here is a Slideplayer step-by-step tutorial of stoichiometry mass to moles and mass to mass

https://slideplayer.com/slide/9194297/

TEST & Webassign 2/14

Please remember to study for the Big Quiz (small test) “Quest” on Mole Conversions, Empirical and Molecular Formulas on Thursday Feb 14th. You have a “Quest” review that were covered in class on Tuesday. The “quest” will be worth 50 points.

Thursday Night (before midnight) you have TWO webassigns that are due! One is mole conversions only and the second one is for Empirical Formulas. Recall that sometimes there is NO subscript of ONE. Any mole ratios that end in 0.5, 1.5, 2.5 or 3.5 will need to be doubled (that’s every subscript doubled). If you have a mole ratio with any element ending in .33, 1.33, or 1.66 then you will need to multiply every subscript by 3. This will give you a small whole number ratio for the formula. Examples are Al2O3, N2O5, Na2Cr2O7, Au3O4. You have had about 40-50 minutes of class time to complete these webassigns, so there should be no excuse for not having them done on time.

Mole Conversions ( with Empirical and Molecular Formulas)

I have uploaded 2 new webassigns for these topics that are also due on Thursday Feb 14th.  I am hoping to have a Webassign “lab” in class to help you get started with these two assignments.

We will have a QUEST (big Quiz or small Test) on this unit Thursday Feb 14th.  There are no quizzes planned but you will have graded assignments along the way-some for completion and some for accuracy.

Here is a tutorial on the Mole Concept

Chemistry Test Re-Takes

The Matter and Metrics Test has been entered into Powerschool.  I found one error on the “B” form of the test and have already adjusted every student’s grade accordingly.  I also decided to add a flat 6 point curve to each test score in light of the delays lost due to Hurricane Florence.  That curve has already been added to the test score in Powerschool.

Now that we have had our first test, I printed the 1st Quarter Interim Grade reports for all Chemistry Classes.  These reports will go home Wednesday and should be signed by a parent or guardian.  I may consider adding bonus points for the the prompt return of signed Interims on Friday Sept 28th.

Students can still bring in Test Review Sheets or Printed Reference sheets for FULL credit, if they have a zero.

Any student that scored below a 70% on the test is eligible for the Test Re-Take.  The Matter and Metrics test grade will be the average of the re-take score and the first score (but not to exceed 70%).  For example, a student that made a 60% on the original test would need to score at least 80% on the re-take to get the grade changed to 70% in Powerschool.   Mathematically 60 + 80= 140/2=70.  Or another example, with a student that originally scored 50% and must make at least a 90% on the Re-take to get the grade changed to 70%:  50 + 90 = 140/2= 70%. If you have questions, send me an e-mail at mbrown2@wcpss.net

I will only offer Test Re-Take sessions after school on Thursday and Friday this week!  Students must bring a hand-made study guide to the Re-Take session.  The Study Guide should reflect the concepts missed on the original test.  Students will have an opportunity to see their Test mistakes on Wednesday 9/26 at the beginning of the period.  Students may write down any concepts that need further study but no photos of the test will be allowed.

As a final reminder, there are now TWO webassigns due this Friday before midnight. Students should access their account at www.webassign.net.    I will have 19  laptops in class on Wednesday and Friday so that we may begin the second webassign together, but the first one should be done at home. You are welcome to bring your own laptop (and store it in my classroom if that helps).

Matter & Metrics TEST Monday 9/24

Don’t forget to prepare well for the Matter & Metrics Test on Monday Sept 24th.  It will be worth 100 points and Interim Grade Reports will include this test score.

Please see the previous post to access the link to print your NCDPI Chemistry Reference sheets.  Staple your reference sheets together and put your name on the first page.  This will be a “practice” grade this week in class.

Finally, there are now TWO webassigns that will be due on Friday Sept 28th before midnight.  The first is the rescheduled webassign from our first unit on Density and metric conversions.  The NEW webassign covers the Bohr Model, electron transitions, and light.  We started this topic in class on Thursday and will finish it by Wednesday this week.  If you bring your own device to school this week, you can use extra class time to work on these two webassigns.

Plate Tectonics Flashcards

Students that MAKE these flashcards can earn Extra Credit on Test Day (Oct 5th).  Here’s what you have to do:

  1. Print the document using the link below.
  2. Use 1/2 of a 3 x 5 index card for each term (or diagram)
  3. Either glue or write the left hand column on one side of the flashcard then put the corresponding right hand column on the other side of the flashcard.  On the document, that means 2 flashcards per row.
  4. Use these to study important Vocabulary!
  5. On the Test Date, put your name and class period on the first flashcard. Rubber band your flashcards together and bring them to science class.  Place your flashcards in the RED picnic basket before we take our test and get EXTRA CREDIT on your test.

Here is the link for the Plate Tectonics Flashcard document.

Test Date moved -yet again

Mrs. Ashburn said that the schools could not be occupied today (Monday 9/17) because many were being used a evacuation centers.  However, she assures me that we WILL go to school on Tuesday Sept 18th.

Right now the 2 make-up A-days are Oct 31st and November 21st.   Recall that Wednesday Sept 19th was to be a vacation day due to Yom Kippur.  The WCPSS School Board may re-visit when the make-up days will occur and announce those changes later.    SO, If we review for our test on Thursday September 20th,  then our Test will be Monday September 24th. Please recall that an earlier post has links to tutorial videos that can help you prepare for the topics covered on the test.  The Test is a product grade worth 100 points.

The Webassign ( at www.webassign.net) will still needs to be completed by many of you.  I have awarded extra points for those students that have already done that assignment.

 

Change of TEST Date

Due to the expected arrival of Hurricane Florence, I would like to move our TEST for the Rock Cycle and Branches of Earth Science UP to Wednesday September 12th.  We will complete a study guide for the TEST in class on Monday September 10th. Students will be able to take their entire packet of materials home to use for review and study.

The Earth Science Pacing Guide will be adjusted as needed after Sept 19th.

Density Lab Friday 9/7

Bring your calculator to lab!  You will need it to do Density Calculations.  Bring your Density Lab handout with you.

Remember to dress appropriately; tie back long hair, no dangling jewelry, no lanyards, or no floppy long sleeves.

We will wear goggles.

Our first Webassign covers Density Problems and Metric Conversions.  This assignment will be due, Sunday September 16th, the night before our first TEST.  You do NOT have to wait to attempt the Webassign.  You may begin to work as soon as you feel you are able to accurately answer questions about Metric Conversions and Density.

Log on to www.webassign.net and enter you password to access your Chemistry Class.  You will only have 3 submissions per item. The entire assignment must be completed by 11:59 pm on Sunday night 9/16.

I will be checking to see that you have PRINTED the Chemistry Reference Sheets for your personal use.  These sheets will be kept in your notebook and can be used for any homework or webassign.  The LINK for the Reference Sheets can be found on our first post.  Simply scroll down to access that link.
