Chemistry I and III,   Oct. 31st - Nov. 4th. activity up-date.


My dear 10th. Students:

Since I got sick last week we are delayed in our 2nd. Partial contents agenda. For this reason the topic for this week will be about Chp. 5 Electrons in atoms.As an introductory activity, at home, try to perform the inquiry activity described in your tx-bk pag. 126. Bring your observations and we'll answer together the think about section.

In addition I'm sharing a web site for you to visit and work with this week main topic. As you read the presentation material you'll be invited to participate writing answer for some questions and perform in some virtual activities linked to the presentation. Try to resolve this activity and all written activity please do it in your notebook. It will be graded as a homework.

Here is the Atomic Theory presentation site: http://www.powershow.com/view/3ae02c-MDI3M/Atomic_Theory_powerpoint_ppt_presentation

For our 2nd. class period next thursday Nov. 3rd.we'll be talking about: Physics and the Quantum Mechanics Model, and performing 2 Lab Practice:  No. 1  Now What do I do?  and No. 2, Atomic Emission Spectra.  Review your tx-bk pages 94 and 137 to check out the materials that you need for each lab and distribute them among each work group as always.

Especial note: for lab practice no.1 we need 2 L.0.05 coins, pre- and post- 2000 coined. Try to collect them from your mom drawer prior being requested respectfuly.

This will be all for this week. Enjoy your weekend.











Dear 11th grade students:

This tuesday Nov. 1st. we'll discuss the information you gather last thursday oct. 27 investigative activity, about Dalton's and Graham's laws of Gas Mixtures. Try to finish what was inconcluded so you can have all the grading for this activity. Then we'll be exploring 

Ch. 15. Water and its properties, and homogeneous aqueous systems. 

As an introductory activity, that you may perform at home: Observing Surface Tension, described in your tx-bk pag. 444 at the begining of ch. 15. I suggest to take some pictures during your performance and then, answer the think about questions, writing your report about it in your notebook. Remember to send the pictures about this practice to my smes mail. It will be graded as homework.

The following site will take you to a youtube video about Electrolytes  and Solution basics:

https://www.youtube.com/watch?v=gZNXm0_irkY  

Try to explore it and we'll discuss it during class time.

On thursday Nov. 3rd. we'll be performing a lab practice named Electrolytes, I`ll make sure we can have all chemical reactives ready for this matter. 

Wishing you a nice weekend, I'll be seen you all in our next class.

Chemistry I and III,   Oct. 24th - Oct. 28th. activity up-date.


My dear 10th. Students:

This week, we'll be reviewing section 4.3 Distinguishing among atoms in your tx-bk pag. 110.
Those of you that have a Periodic Table please bring it along because we will be checking some values in it. Those that don't have one, please try to get one as soon as possible so we wont have any delay in this importan topic.

Also we'll perform a lab practice, The atomic mass of Candium, so for this purpose we will need that each group may brig a bag of candies of different colors, as those shown in your tx-bk pag. 120.

For the 2nd. class of this week we will be resolving som exercises to calculate composition of an atom, atomic mass, and the introduction of Chp. 5 Electrons in atoms.

Try to see the following video about this topic so you can have an idea of it prior to our class about electrons. Have a nice and productive week, my dear students.

Here's a Bohr's atomic model for you to make an image of how the electron moves around the nucleus of an atom.

Dear 11th. gde students:

This week we'll be finishing ch. 14 contents with the combined gas law, the Ideal gases and mixtures and movements of gases. We'll check out the materials to perform the small scale lab described on your tx-bk 437 to finish up this chapter.

Here's a video to help you out with Dalton's Partial pressures law:

https://www.youtube.com/watch?v=RqffPYOoxd8

A work sheet with more practice exercises will be resolve to practice Combined law, and Dalton's law of partial pressures.

That'll be all for this 1st. week of the 2nd. partial. See you in class!

Chemistry I and III,   Oct. 17th - Oct. 21st. activity up-date.


My dear 10th. Students:

For this week, we`ll be checking out our 1st. partial final grading and performing a feedback of those topics that showed to be not as well understood and learned as expected, during this school year's first academic period.

This tuesday I've programed to develop a dialogued exposition with Ch.3 Conversion and Scientific Notation problems worksheets, to make a closure to every doubt that you could have about these important calculations.

By thursday we'll be starting Ch. 4 about Atomic Structure.

For those of you that need to undergo the leveling process, there is a guide of conversion exercises with a cross word puzzle to solve, that will be delivered and explained during our regular chemistry class; these activities will be valued as leveling instruments for you to aprove the partial grading.

I hope that you can accomplish all you can and work hard this new academic period.

This tuesday I've programed to develop a dialogued exposition with Ch.14 The Behavior of Gases, key concept theory, and resolve some problem's worksheets, to make a closure to every doubt that you could have about these important calculations.

By thursday we'll be starting Ch. 14.3 about Ideal Gases, and 14.4 Gases: mixtures and movements.

For those of you that need to undergo the leveling process, there is a guide of study and some gas behavior exercises with some match terms items to answer, that will be delivered and explained during our regular chemistry class; these activities will be valued as leveling instruments for you to aprove the partial grading.

I hope that you can accomplish all you can and work hard this new academic period.

CHEMISTRY, ASSIGNMENT LETTER for the Oct. 10th - 14th. week.




My dear 10th. grade students:

To undergo the next final evaluation for this 1st. partial in our class of Chemistry you need to prepare yourselves studying with your text book from pag. 68 to 90 about significant figures, and the following key concepts about Atomic Structure:

• How Dalton transformed Democritus’s ideas 
• The importance and use of the periodic table. 
• The types and description of subatomic particles, in an atom.  
• The nature and meaning of  Isotopes of an element 

I'll check out your notebook this friday, I hope you have all the lab practices reports resolved and the activities you did with Mr. Galeas. These evidences will be graded and added to your accumulative grade.

Good lock in all your evaluative activities.

Dear 11th Grade students:

For your Chemistry exam you need to study with your text book from page 413 to 425, paying close attention to the gas behavior laws of Mr. Boyle, Mr. Charles, and Mr. Lussac, as well as the combined gas law. Resolve the sample problem of each topic and then the following 2 practice problems below, and study the theory explanation that preceds each calculation.

I'll check out your notebook this friday, I hope you have all the lab practices reports resolved and the activities you did with Mr. Galeas. These evidences will be graded and added to your accumulative grade.

Make use of the following youtube sites to see a clever explanation about these topics before you study these concepts.

1) Boyle's and Charles's gas laws https://www.youtube.com/watch?v=vG6M7LuNgag

2) Combined gas law: https://www.youtube.com/watch?v=m578esxRSvQ

Good lock in all your evaluative activities.
