Fall Break 2018

Fall Creek FallsKids-

You made it to Fall Break! You have one week of homework due on Oct 18 after Fall Break. There is not a new Prelab due because the Molecular Models Lab does not require one. You do have a Postlab due (5.2). Use p.152-153 to help you write it, especially the red box, include the two vocab words from book, also the words polar and non-polar, and the word “surfactant.”

When you get back, we’ll be very close to celebrating  National Mole Day!    moleparty

Enjoy your time off and stay safe! jb

Week 7 of Chemistry ✅

Students,

One more class before Fall Break! You can do it!

Hopefully, things are starting to click by this point for you. If not, call/email/come see me ASAP with your questions.

The Chapter 4 Test will be open tomorrow through next Wednesday. Bring any math work to class next week. Here are some videos to help with Chapter 4 if you need it. Choose from any of the electron configuration videos.

Help session will be next Thursday, Oct 4, in my classroom at 2:30pm. Get some help before we move on with Chapter 5.

Have a great weekend! jb


Week 6 of Chemistry ✅

Students-

Nice job on the flame tests! Don’t forget to include the six words/phrases below from the board in your Postlab due Thursday (along with reading p84-87).  If you don’t know what something means, use the Google machine or your textbook’s glossary.  Be sure you identify your two unknowns in the paragraph as well.

The Chap 3 Test opens tomorrow at 8am and closes Wednesday at 10pm.

See you soon!  jb


HW Due Sep 20

Students,

Nice job on the math and the puns today!

For next week:

Be sure you have handwritten your Prelab into your lab notebooks as usual (according to the Flame Test Lab linked to the HW site).

Please note that the data tables are to be hand-drawn into the V. Data Section before coming to class. BaCl2 was left off the table, please add it in.

Be sure you are dressed appropriately for lab. Cover feet and legs.

I look forward to seeing you then! jb


Chemistry Week 4 ✅

Students,

Prelabs are looking great. Post labs are getting better. Here are a few reminders for this week:

1- Chap 2 Test will be open Friday @ 8a – Wednesday @ 10p. You have 60 minutes.

2- Your Postlab should be labeled with 5 things: what, why, how, data, errors. The data this week is just observations about what happened.

3- for extra credit, email me at homeschoolscience@live.com and tell me the name of the substance in your body that catalyzes the decomposition of peroxide. (Why does a wound bubble with peroxide- don’t say oxygen?)

4- Quiz Sep 13 on the first 36 elements. Know the symbols and names, spelled correctly. There’s a quizlet on the homework page.

Have a good weekend! jb


Chemistry Class #3 ✅

Hey Kids…

Great job on the Conservation of Mass lab!

For this week:

1- Please include your two masses, color changes, temperature changes, and percent error in your Postlab, labeling the “what, why, how, data, and errors” we talked about today. Explain why this is called an “exothermic” reaction in your Postlab (look it up in your book for more information). For extra credit, email me (homeschoolscience@live.com) what the two different colors of solution represent from the lab today.

2- Quiz on Sep 13 over the first 36 elements. Know their symbols and how to spell their names. You do not need to know the atomic number. If someone creates a Quizlet on these, send it to me, and I’ll post it for everyone.

3- Print two copies of the Periodic Table that is located here and bring next week to class.

Enjoy your vacation from labor on Labor Day Monday! jb


2nd Week of Chemistry ✅

rulersStudents-

Great work on Thursday with your first lab!  Here are a few reminders as we look forward to the third class!

  • New homework is posted, due Aug 30.
  • Your Chapter 1 test is posted on the calendar on Engrade. You are to use your calculator and brain only. Otherwise, you are cheating.
    • The test opens tomorrow (Friday) at 8am and closes Wednesday at 10pm.
    • Be sure you have one hour of uninterrupted internet time.
    • Complete all math work on notebook paper. If you are unsure if work is required, show your work. No work = No credit.
    • Turn in your math work on the notebook paper next Thursday in class (Aug 30) for full credit.
  • You have your first Postlab (Section VI) to complete this week.  Review the Lab Report Format file first. Be sure to include your important data (your actual numbers), any errors, what happened, and why. Use 3rd person.
    • If you completed Experiment 1.2 in class, write the Postlab for 1.2. Read the top of p.18 in your book for some ideas.
    • If you completed Experiment 1.3 in class, write the Postlab for 1.3. Read p.26 in your book for some ideas.
  • You have the next Prelab to complete this week.  This week’s experiment will come from the linked handout (on the Homework Page- Conservation of Mass Lab). Follow the same steps you did last week to complete the Prelab (Sections I-IV).
  • Quiz next Thursday, Aug 30, over metric conversions, lab equipment, and lab safety rules.
  • There will be another quiz Sep 13 over the elements and symbols #1-36 on the periodic table. You need to know the symbol and be able to spell the names of those elements correctly. Print a periodic table for class from the Homework Page to study.
  • If anyone makes flashcards for these, send me the link, and I’ll post them.

Have a great week! jb
