My dear 10th. Students:

This week is a special one since we need to inform the midterm report of our class activities.

On monday we`ll share 2 videos to reenforce the Electron arrangement in atoms and introduce the Physics of the quantum mechanical model of atoms. The class work will finish with the 5-1 and 5-2 Section Assessments. For our small scale lab we need to buy a diffraction grating, so we'll try to perform this lab practice on wednesday. Please try to check on this lab materials in your tx-bk pag. 137, to have all we need by wednesday nov. 9th. Our last topic of this week is going to be Atom Spectra and Quantum mechanichs.

As home work, you need to resolve the Organizing Information concept map described in your tx-bk pag 148. All of this will be graded and included in your mid term report.

See you monday nov. 7th.

My 11th. grade Students

This week is a special one since we need to inform the mid term report of our class activities.

On tuesday Nov. 8th we'll talk about Heterogenous Aqueous Systems: Suspensions, colloids, and emulsions,
If we can get the reactives for Lab practices: Diffusion and Electrolytes, both will be performed on Thursday. In the case that the reactivs couldn't be adquired, then we'll assign other activities to fulfil your mid term cumulative.

As homework you have to resolve sections 15-1 until 15-3, in your note book and have them ready to be check out on wednesday nov. 9th.

That will be all for this week.

See you tuesday.

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.

Orbitals the basics: https://www.youtube.com/watch?v=Ewf7RlVNBSA


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.

Tegucigalpa, M.D.C.  August 16^th, 2016.

Greetings to the big family of St. Mary’s Episcopal School.

Specially meant to my future Science, Biology and Chemistry students, form 7^th grade to 11^th grade.

I’m about to start my first year as a Science teacher for this, respectful and kind, educational institution. I cannot hide my excitement and optimism at the moment because I believe that if you get to know where we come from, and how our matter is conformed of, this knowledge could lead you to new investigations and innovations in technology that might carry out a lot of activities yet to improve.

My personal goal is to “promote and advance scientific and investigative development through education and practice within the walls of this distinguished school, among its youthful population.

In words of Dr. Doug Ashcraft, Head of Idyllwild Arts Academy, “Cultural development and positive personal growth, mean that we want to do more to produce skilled artists”, in my case, I will like to promote novel and skilled investigators that can optimize, with my classes on Science, Biology and Chemistry, their college studies in any career they choose.

So, welcome students to my classroom and let’s see where this new academic year could leads us.

My best wishes to all of you.

Mrs. Aura Graciela Arevalo Villeda

Master in Education of Natural Sciences

St. Mary’s Episcopal School.
