WLW Day # 4: Water as Solvent


Science Experiment # 3: Water as Solvent


Materials needed:

* chalk
* filter paper
* heat source
* lime powder or tablets
* phenolphthalein
* 2 pyrex beakers




Instructions:

* Crush some chalk
* Mix chalk into water in a beaker
* Pour the mixture through filter paper. The water appears to be "pure".
* Boil the water or let it evaporate away.

Q: What is left?

* In a beaker, mix lime powder or tablets and water.
* Filter until clear.
* Fill another container with water.
* Obtain some phenolpthalein (Hln or phph) and add a few drops to a glass of "pure" water.
* Add a few drops to the water mixed with lime.



  Q: What are the results?
  Q Relate to hydroponic gardening (growing plants in water instead of soil)?

What we learned:

* Water's power to dissolve substances (e.g. chalk + water)
* Substances can be transported when dissolved in water  (e.g. chalk + water or line + water)
* Water can carry out chemical reactions (e.g. lime+water+Hln)
* A clear water does not always mean "pure" water. It may carry substances or minerals.
* Application: Water passing through soil dissolves some of the minerals and transports them through the soil to plants and animals, and contributes to the salinity of the sea.

WLW Day 2: Ionic Bonding

Science experiments time. . .

Experiment # 1: Ionic Bonding



Materials Needed:

2 inflated balloons                                          
thread                                                             
string                                                              
piece of material (nylon, wool, or fur)
nylon stocking
piece of white paper

Instructions:
* Tie the ends of the thread to the knotted ends of the balloons, and tie the middle of the thread to the middle of the string.
* Rub the balloons with a piece of material, and then pick them up by holding the ends of the string and stretching it to its full length.

   Q: What happens to the balloons when they are close together?
    Explanation: The material used to rub the balloons transferred electrons to the balloons.
   Q: What electrical charge does the balloon have now?

* Cut 2 3X12 inch strips of material from the nylon stocking.
* Place both strips on a piece of white paper and rub them briskly in your hand.
* With your fingers lift the 2pcs of nylon and hold them side-by-side.
    
    Q: What happened? Why?

* Now bring one of the nylon strips near one of the balloons.

   Q: What happened?

 What we learned:

 * atoms with the same charge, repel
 * atoms with opposite charge, attract/stick together = Ionic bond

  • Teasing needle, straight
  • Test tube rack, 6 holes
  • Test tubes, small 13x100 mm
  • Test tubes, x-large 19x150 mm
  • Thermometer, Celsius, 12"
Yes! a very long list of items that. . . after the school year, we will have our own Science Laboratory! LOL!

Hopefully we will be able to complete them before the end of the school year. One Unit at a time. :)

Unit 2 (Basis of Life) will be about : 

* molecular models
* ionic and covalent bonding
* inorganic compounds experiment about solvent, thermal properties of water, acids,  bases and salts
* chemical reactions like electrolysis and using yeasts
* organic compounds like testing for starch, sugar, oil and protein in some food
* and,  properties of enzymes

So here's our stash (in photo) :





Grade 10 Unit 2 materials

stored securely (p.s. we need a bigger container soon)

Oh how this simple exercise of gathering all the materials reminds me of how I love Science back when I was in school. 

Rocking Science we should be!

The Road less traveled

...yes, we are choosing the road less traveled. Where it will lead us and how it will turn out will be all dependent on us... and by God's grace!

Homeschooling is foreign to most Filipinos. When I opened the idea, we were swamped by so many questions:

* Is it allowed here?
* Why? is she failing? 
* How about socialization skills? Baka maging anti-social or worst, loner.
* What kind of education will she get?
* etc, etc

Let me try to answer as best as I can...

Is it allowed here?

Yes.  Apparently, there are several schools offering distance educations for several years now. In fact, the University of the Philippines already has Open University for college students! Surprise!

Homeschools in the Philippines

Why? Is she failing?

To borrow a popular local lingo:

"Pagnag ho-homeschool, bagsak na agad? Di ba pwedeng talented muna?" or better yet "genius muna" and our traditional school can not support his/her needs?

Apparently,  comments like these are born out of ignorance.  So let me enlighten the uninformed...

There are so many reasons why families homeschool. Most Filipino families do so because: (not in any particular order)

* They find the Philippine curriculum inadequate
* One-on-one education is far better than generalized education
* They want to take charge of their kids education and values formation
* Child with special health concerns
* Kids with special needs (sadly, our traditional school do not and could not support them)
* Kids with special talents (i.e. sports, arts)
* Families that travel a lot

Of course, DEPED also has a special program for children of the less privileged who wants to finish college. But I will not delve into that anymore.

How about socialization skills?

The most feared "effect" by the uninformed.

And this is not true. In fact, as per observation, most of those who are homeschooled can carry a conversation with an adult, like an adult.

Most homeschoolers are part of a support group. Where group activities can be conducted for a chance for kids to meet fellow homeschoolers and do activities together.

And if your kid is into other activities i.e. sports, music, art, dance, theater, etc., being anti-social will be far from being true.

In the case of Gia, she is going into homeschool at 13years old. Has been to a traditional school where she had a lot of socialization. And, she is into ballet, where she has to interact with her teachers and fellow ballet students.

So this is the least of my fears...

What kind of education will she get?

A lot and far better based on what I observed and what I have seen and read.

What and how the child learns will be dependent on how good and patient the parent-teacher or tutor will be. Of course, the curriculum adopted is an important factor too.

Most of the homeschools here in the Philippines are DEPED accredited. If you prefer to use your own curriculum, there are some schools that lets you do so as long as it satisfies DEPED's guidelines.

And, the most important part is, they will not be limited to the classroom in their learning! The world becomes their classroom!

Lifepac uses a lot of experiments, field trips to neighborhood parks, places, and activities outside of the classroom.  Making learning a lot of FUN!

With that, let me share Robert Frost's popular Poem:


 Looking forward to a school year of so much learning for both Gia and myself!

The books have arrived!


...this is getting more exciting!...and more challenging!

The Lifepac books have arrived and so have the local books!  Now, I have to go through each and do the lesson plan before we start the school year...

Thank you to fellow homeschool bloggers, I will be using Homeschool Tracker to do just that.  Assignments, readings, activities, field trips can be included. I will  be using the downloadable free version for lesson planning as HCSI will be providing me with their own grade sheet program.

...this is it! let's rock the homeschool world!
