Lab Report: What happens if put bones into vinegar.

My son's lab report for studying human bones and learning how a base will dissolve the calcium in bones.   I needed to assist my son in preparing the bones, but otherwise he did the experiment himself.  He asked me to handle the bones after they sat in the vinegar.  He took the pictures.  :)

Hypothesis: Vinegar would weaken the uncooked bone, and it would not weaken the cooked bone in vinegar.   The bones not in vinegar... The uncooked one would not break and the cooked one would break. 

Procedure: We put one cooked bone and one uncooked into vinegar and let them in there for five days.  After five days we took them out too see what would happen.   We put one uncooked and one cooked bone on a plate and left them to sit for five days.

The bones in vinegar were both bendable.  The uncooked bone was more bendable than the cooked bone.  You could bend the ends of the cooked bone but not the middle.   With the uncooked bone you could bend the entire thing.   The ones in vinegar, the cartilage came off, it was gloppy with the uncooked one... spreadout with long strands, the cooked one stayed together but was mushy.  Both bones not put in vinegar were not bendable.

Conclusion: Vinegar weakens bones and cartilage.  Letting bones air dry makes them harder.   Vinegar is a base and bases dissolve things.

Book Series: Parenting - be an ambassador parent

Paul David Tripp wrote an interesting parenting book called Parenting: 14 Gospel Principals.  I thought it might be interesting to read through this book.  Join in if you would like.

I decided to start with the introduction rather than digging into the first of 14 chapters.

In the introduction Mr. Tripp talks about how as he has travelled the world helping parents learn to do this job better, he has discovered that what they need help with is "big picture parenting worldview".   Having this worldview will give us grounding in what God calls to do as parents.. it explains, guides and motivates all that we do.   Ergo as he writes this book he wants parents to understand the gospel behind good parenting practices.

To start with, we have to know who we are in relation to God, to what life is all about and to who your children are.  This knowledge is of paramount importance.

Mr. Tripp wants us to move away from the ownership idea of parenting to the idea that we are ambassadors.   We need to remember, these children aren't ours.  They belong to God and we need to parent them with that idea in the forefront of our minds.

As we parent, we need to be aware of something.   As much as we desire to be ambassadorial parents..... we will fail.  We will want to do things our way, to meet our needs, to just want the short run satisfaction.  We'll fail.  But that's not the point.  The point is to keep striving to do God's will.

Questions we could ask ourselves.
1. Identity - where do we get our identity from. 
2. Work - working to turn your children into something?  or helping them develop into something more?
3. Success - which is more important the end product or what you are doing?
4. Reputation - Living with the craziness that children can bring... does it affect who you are or does it reflect your children?

An ambassador is called to represent the message, methods, and character of the Owner to their children.  (p.20)

The next 14 chapters will introduce different principles to reflect upon to help us do the job of ambassador of God to your children effectively.


I read the thought of "you will fail" and it made me smile.  I so often feel like I am failing in what I am doing as a parent.   But it strikes me that seeing oneself as an ambassador of God before the eyes of my son... strikes me as a grave responsibility, as well as taking a load off.  It's not my job to make my son into's God's job.  Mine is simply to show God to him.  That's it. 

Recipe: Homemade Marinara Sauce

Take a few marina sauce recipes, see what they have in common, and find a way to make it work.  This is what my hubby came up with.

Blogging Alphabet: E is for Edgewalk

Welcome to week five of blogging through the alphabet.  I am SO pleased that you have come to join us.  :)

Check out this link to see the rest in this series eh?

Anyways, as I go through the alphabet I am focusing on all things Canadian and this week we couldn't get much more Canadian than the CN Tower.   Did you know they have added an Edgewalk?

Imagine being able to walk around the highest building in Toronto?   Wouldn't that be breath-taking scary!!!  (at least in my eyes, my son says "that would be so cool!!!")

 Defining the Toronto skyline at 553.33m (1,815ft5in), the CN Tower is Canada’s most recognizable and celebrated icon. The CN Tower is an internationally renowned architectural triumph, an engineering Wonder of the Modern World, world-class entertainment and dining destination and a must see for anyone visiting Toronto. Each year, over 1.5 million people visit Canada’s National Tower to take in the breathtaking views and enjoy all the CN Tower has to offer. (source)

Canadian National built the CN Tower in 1976.  Their desire was the demonstrate the strength of the Canadian industry through building the tallest tower in the world.  It was a very ambitious product that involved 1537 people working 24 hours a day, five days a week for 40 months.   Worked started February 6, 1973.

Throughout it's history, improvements and changes have been made to the CN Tower.  The Edgewalk was added in 2011.  The Edgewalk gives people a chance to walk hands-free on a five foot walk completely encircling the tower.  It is 1168 ft above the ground. 

Adventure lovers can go around in groups of six.   As they walk they are attached to an overhead safety rail.  A trained guide walks with them.   The 30 minute walk is part of a 1. 5 hour event. To learn more check out Edgewalk CN Tower
