Life Cycle: Human Body Part II

Wednesday, October 22, 2014

The second and last part of our Human Body Study includes the Skeletal System and a brief introduction to the Permanent Teeth Development. 

The Human Bones (Skeletal System)

Previous works on Skeletal System can be found here and here.

This year, I added some depth into our study.  We started our work using the Skeletal Nomenclature Cards.  This is an independent work for him. 

SKELETON

Next, I have this small miniature of the human skeleton which I bought on a Euro Store and I started to cut it into pieces.  Here showed Mavi the bone models and compare it to our image.  We talked about the functions of each bones in the human skeleton.  We also tried to compare the arm and the leg bones.  Pointing out to Mavi that bones in the legs are longer than the arms.DSC_0815

We played around with the bones.  Making different formations.  Mavi thought that this was funny LOL.

Forensic Anthropologist (A Play Pretend)

I buried the bits and pieces of the skeleton I previously dismantled in a bowl of oatmeal.  Here I asked Mavi to dig, brush and put the pieces of skeletons back together. “Oh, just like the dinosaurs Mommy!” he exclaimed.

And much to my surprise, this was an easy task for him.  He was able to complete the work in no time. Though he wasn’t challenged, he really liked digging the bones and scrubbing the oatmeal off.DSC_0864

 

The Bone Experiment

We conducted an experiment on a chicken bone. This is to demonstrate the effect of acids on bones. 

What you need:  Vinegar, chicken bone and a jar

After cleaning the cooked chicken bone, we place it in a jar filled with vinegar.  After 24hrs, we remove the bone from the jar and examined it, its texture and flexibility.  Mavi observed that, the bone’s flexibility increases daily (for 5 days) having a feeling of a rubber.

This is because of the loss of calcium in the bones after exposing it to vinegar which is an acid and reacts chemically with the bone.  As a result, Mavi and I discuss the importance of calcium in our body specifically in our bones.  How it gives the bones strength and firmness.  We also talked about the foods that are rich in calcium, which we need to eat in a daily basis for maintaining healthy bones.

Books

Our book from the library the Eyewitness Skeleton [aff. link] was also a great helped.  It shows the contrast of human bones and animals bones, the structure and formation.

And that concludes our Human Body study for this year.  Hope that this post will help you with your own skeleton activities.

Color Gradient Painting

Sunday, October 19, 2014

We try to have an art class every Friday as what I indicated in our October Calendar.    I bought new sets of paint last week, they’re 80% organic, non-toxic, water washable and doesn’t have the strong smell like that of Crayola.  So my son had a renew interest in painting and he’s been doing it randomly not just during Friday.

This idea was from a picture I saw in my Facebook newsfeed and I wanted to try it with Mavi, teaching him the colour progression… from light to dark or the other way around.

He picked the primary colours and the green. We added 3 drops of white paint each time we lighten the colours.  Son totally enjoyed this activity!  He especially loves the part wherein we changes the shade of the colour and he gets excited to see the effect.

So here’s Mavi’s work and mine. I didn’t get to finish my work as I ended up assisting him in his colour mixtures.

As an extra work, he ended up mixing the primary colours…. to produce secondary colours so he can paint a rainbow. A few years ago we had colour mixing activities, you can pay it a visit as it became really popular and was featured in other blogs as well.

I’m so happy of his renewed interest! And with the new paints, I can allow him to do lots of art works without worrying of the strong paint smell :D

Tally and Finger Counting Cards

Friday, October 17, 2014

I mentioned in Facebook that this activity (one to one correspondence) of numbers is one of my son’s favourite works.  Here, we used the number symbol cards, Montessori beads, counting finger cards, dot cards, number words and bear counters.

You can get the number cards, tally and finger counting cards from this post of Linton Academy.  The number dots were made by yours truly. Unfortunately, I lost the file and couldn’t retrieve it.  But this is so easy to do.  The number words were homemade as well (handwritten).

Enjoy!

The Nile River

Wednesday, October 15, 2014

NileRiver

Continuing our World History study, we read about the people of Egypt and the richness of the Nile River.  We pinpoint the location of the river in the map and how the civilization of the Egyptians started in this great river.

After reading Chapter 2 of the SOTW, we proceeded immediately with the mini-projects it suggested. One of which is creating a model of the Nile River.  We could have done this outside, but the weather has been really terrible this week so we made use of our art crafts at home and whatever we could find to make our model as close to the description of the river.

Below in the picture, Mavi using blue crepe paper for the river forming a delta going to the Mediterranean Sea.  Here we discussed what is a “delta”.  A good review of our landform lesson.

He added some playdough to plant our mini trees (from our front yard) and made pyramids out of LEGO bricks.

I added accent to his project by painting the base with green paint to represent some lush farmlands. And this completed his Nile River Project!

Next I will be sharing our map work and the first mummies :D
