Experiment - Egg Motion

Learning Law of Motion with an Egg

A Spinning Eggsperiment

Materials Needed:

2 eggs: 1 hard boiled, 1 raw


Spin the two eggs and then gently stop them with a finger.


What happens when you stop the eggs?



I took a whole hard boiled egg and a whole raw egg (with the shell), and told the kids that I was going to show them something interesting with the two eggs. You can also have it ready from before then ask the kids which one is boiled which one is not? They might guess it right but there is no way to be sure. So what do you do?

Spin the Eggs. 


I told my Lil Muallims to pay close attention to the eggs and to notice which spins well and which one spins slow. While the eggs were spinning I tough them gently with a finger to stop them, and then quickly moved away my finger. They were surprised to see what they saw.

(I couldn't get a picture of the eggs spinning... they lookes so nice!!)

What Happened?

One egg stopped while the other kept spinning slowly for a few more seconds. 


I asked the Lil Muallims why?

I could see deep thinking on their faces.

Then I asked then what happens when we are all driving in a car and baba has to push the breaks suddenly?

Lil Muallims in unison: "We move forward?"

Me: "Why? That's a little physics for you here. That's because even though your are sitting still you are supposed to be moving in the same direction and in same motion as the thing you are travelling in. So even when baba hits the breaks and the car stops, because you were moving with the car, you first bend forward..... proving you motion.

So why do you think the egg is still moving?"

Lil Maullim thinking: "Probably because the liquid inside the egg was still moving"

Alhumdolillah! Great Answer Mashallah!

The following explanation from Steve Spangler's web site explains it simply

Hardboiled or Raw?
"Can't remember which egg is which? The answer is only a spin away. Simply spin the egg and pay close attention to how well it spins. If the egg spins well, it's hardboiled. However, if the egg wobbles and spins slowly, it's raw. A hardboiled egg is solid inside whereas a raw egg is fluid. When you spin the raw egg, its center of gravity changes as the fluid inside the egg moves around. This results in the wobbling motion you noticed in the raw egg. As soon as the raw egg starts spinning, touch it briefly with your finger just long enough to stop it. When you take your finger away, the egg will continue to spin for just a quick second. This is due to the inertia of the fluid inside the egg. When the hardboiled egg is spun, the solid center immediately moves with the shell, causing little resistance to the spinning motion."

What we learnt ?

.To tell which egg is boiled which one isn't simply test them for inertia.

What is Inertia

Simply put Inertia is: 

"An object in an object at rest  remains at rest and an object in motion remains in motion, till an outside force is applied to it"

This is Newton's first law of motion

Understanding Quran


Alhudmolillahi Rabbil Aalameen for all that He makes Available for our benefit. May we be the ones to utilize it too Ameen.

 I am abundantly grateful to Allah Subhanawata Allah for always showing me the light whenever I am looking for something in particular. It's not only surprisingly amazing but also very humbling that whenever I seek, think or pray for finding a  good resource for a certain topic, my Ar Rahman brings it forth for me. What is even more fascinating is that it usually comes from where I least expect. May Allah make me truly thankful.

In our homeschooling I always look forward to have Lil Muallim's Abi help out and do certain topics with the kids. It's not always consistent, but whatever he teaches has been very beneficial and the kids really cherish it too.

So this time round when my husband called Lil Muallim #1 to do something with him, I was ecstatic. Why? Because, he had called him to watch a video course, whose worksheets I was already trying to use with for Lil Muallim. I have to admit we hadn't done them for a while but they are all set up in his Quran Translation file. I also hadn't had a chance to check back on the website for quite sometime, so when my husband opened the link for the whole course on video........... and he doing it with Lil Muallim #1, you can only imagine my excitement and Shukr  ALHUMDOLILLAH ya Rabbal Alameen.

It has been my dream for myslef and my kids to be able to understand every word of the Quran as we read, or hear it. I have made my own system to try and reach that goal. I will post about that another time Inshallah. For now I hope a lot of you can benefit from the following course. I have added the videos for the first two lessons here for a preview for you.

Lesson 1a Understanding Quran Made Easy Short Course 1
Lesson 1b Understanding Quran Made Easy Short Course 1
NOTICE!!!! The Understand Quran Academy does not offer this course for free anymore. Please take their membership as it suits you and benefit from their hard work and support their cause Inshallah.
Understand Quran Academy There are many more treasures on their website.
The methodology and technique used is truly effective and the worksheets are a good revision. I am also trying to do extra exercises with the kids to review each lesson. I will be posting it lesson by lesson. Inshallah. May Allah put barakah in our time. Ameen.
May Allah reward the brother and his team generously for this tremendous endeavor

Experiment - Cellular Membrane and Osmosis

Lil Muallim # 1 "Cellular membrane and  Simple Osmosis"

Studying the basic structure and characteristics of a cell and it's membrane.

What I know :

The egg is actually the largest cell in the world. The calcium carbonate makes up its outer shell. It is made up of  calcium carbonate (CaCO3) crystals. This is just an outer coating protecting the actual cell membrane. The cell membrane encloses the eggs yolk (nucleus) and white (cytoplasm).

Simple anatomy of an egg can be learnt here

Materials Needed:
An egg
Clean glass wide necked bottle

vinegar coffee maker
Regular white vinegar


Paper Towel


  1. Place an egg in a medium sized jar.
  2. Fill the jar with vinegar until it covers the egg
  3. Leave it for 3-5 days
  4. On the 4th or 5th take out the egg and wash it gently with water removing the powdered calcium coating
  5. Observe the egg in the dark with a torch
  6. Place the egg on absorbent paper towel and try touching it gently
  7. Leave it like this for about a day
  8. Place the dehydrated egg in a bowl of water overnight


#1 Bubbles started forming inside the jar as the acetic acid in the vinegar starts to react with the calcium carbonate crystals in the egg shell.

# 2  After a day in the vinegar the egg shell started softening.

# 3 The appearance of  the egg shell changed as its chemical composition changed. The solid Calcium Carbonate crystals broke apart in the acetic acid releasing carbon dioxide gas.

# 4 The calcium turned into powder and was easily removable when rubbed gently

# 5 The egg looked slightly larger because it had absorbed some of the vinegar, showing that the cellular membrane is semi permeable (can pass through some air and moisture) and osmosis (simply the transfer of molecules from one medium into the other).

# 6 The cellular membrane is translucent and the yolk can be seen bobbing in egg white (albumen) through it, because of it bright color 

A raw egg with it's egg shell dissolved

(you can also try looking at it in dark with a torch I couldn't get a clear picture with my camera but this website shows how we saw it) 

# 7 The egg was bouncy showing the elasticity of the cellular membrane as it is partly made up of keratin (a fibrous protein)

# 8 When left to dry out on an absorbent paper towel the egg shrivels up as it paper towel absorbed the moisture from egg. This again shows the semi permeable characteristic of the cellular membrane 

# 9 When the dehydrated egg is placed in water, it restores its shape as it regains moisture through osmosis.

# 10 It is still bouncy as before. Subhanallah!


The cellular membrane encloses and protects the inner parts of the cell, It is stretchy because of keratin a string fibrous protein. It is also translucent. Osmosis can easily take place as the cellular membrane is semi permeable.


The egg does bounce watch it in this video I found 

NOTE: We used the same egg frim Lil Muallim # 2's experiment and we did the dehydration and hydration part twice on the same egg and it worked perfectly.\After the second hydration it was still bouncing as the first time.


Experiment - Calcium in Teeth /eggshell


Of recent I've been trying to be more pro active with doing Science Experiments REGULARLY with my Lil Muallims. This made me think I should also record and share them here one by one Inshallah. So keep checking. I hope to post one experiment in detail every 1-2 weeks Beidhnillah.


Last week we did a fascinating experiment. It was awesome....Subhanallah. The experiment tied in with two different topics being covered by the kids. This one was for Lil Muallim # 1

  "Calcium in teeth"

To find out how acidic and carbonated drinks effect our dental health.

Materials Needed:
An egg
Clean glass wide necked bottle

vinegar coffee maker
Regular white vinegar


How will the vinegar (acid) react with the calcium in the eggshell. Will it effect it in anyway?


  1. Place the egg carefully in a glass bottle. 
  2. Pour vinegar until it is completely immersed in the vinegar
  3. close the bottle and leave for 3 days


Immediate: Bubbles form around the eggshell. They look like the bubbles of  carbonated drink poured in glass.

 Our pictures didn't come out well.. will try again next time

Discuss Reason: When calcium carbonate (the egg) and acetic acid (the vinegar) combine, a chemical reaction takes place and carbon dioxide (a gas) is released.  This is what the bubbles are made of. (source)

DAY 1: Bubbles still surround the egg. Try touching the egg shell after a day. It will be soft and squishy. Don't press hard.

Discuss Reason: The chemical reaction keeps happening until all of the carbon in the egg is used up -- it takes about a day. When you take the egg out of the vinegar it's soft because all of the carbon floated out of the egg in those little bubbles. (source)

For older kids: When you submerge an egg in vinegar, the shell dissolves. Vinegar contains acetic acid, which breaks apart the solid calcium carbonate crystals that make up the eggshell into their calcium and carbonate parts. The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide—the bubbles that you see. (source)

DAY 2: Bubbles have reduced a bit but are still present. 

DAY 3:  Follow the steps:

Step #1: Remove the egg from the bottle gently. It's quite squishy on touch. Gently rub your fingers on the egg. Powdered calcium rubs off on our fingers showing the inner membrane of the egg. Subhanallah!

Step # 2: Rub off all the calcium until all is removed revealing the inner membrane of the egg. You can do it in a bowl of water or under gently running tap water.

Step # 3: Hold the egg an inch above the table and gently let go. The egg will bounce. Subhanallah!


Drinking a lot of carbonated drinks can make our teeth weak as they react with the calcium in our teeth and damage its enamel. (besides the fact that they are not good for health).

Watch Video of Bouncy Egg


There are other version of this experiment too. Will be posting them too soon as we do them.

Hand Eye Coordination Secondary Level

Speedy Movements

My Lil Muallim # 3 got the whole house very excited today. What was the cause of all the excitement?


He was so full of it after doing it with his friends. Back at home we looked at some record Speed Stacking videos on the official Speed Stack website..... yes Speed Stacking is actually a sport and there is a WSSA - Word Sport Stacking Association. It was a revelation to me ! 

Wourld Sport Stacking Association

You can also check out the Speed Stacks at Amazon and read reviews by clicking on the image below.


Check out some of the OFFICIAL RECORDS videos 

They are quite interesting......

Personally, I would not like Lil Muallim # 1 to chase a record, but for me this is definitely a good way to improve hand eye co-ordination and make swift hand movements. Now those are skills that can be useful in sooooooo many ways.

There are some tutorial videos on the official site but there's too much music and other things I am comfortable not comfortable with.

Soooo........I found this tutorial.... the fact it's given by a kid for me is beneficial in many ways. It was simple, homely and kids friendly. Lil Muallim # 3 was impressed how a kid was explaining so well.... ahem (now that's a good skill to have isn't it :) ) Well back to the tutorial check it out here.


After going through the videos and discussing the skills that can be attained from this. Lil Muallim # 1 said ever so innocently, "Mama I like how you like everything I like" .....aaaawwwww Alhumdolillah

Speed Stacking at Umamah Learning Academy

It is notable that the shape of the cup really makes it work well. But before even thinking of investing into this my mind started rolling with what other options I have.....hhmmmmmm

How the design of the glass effects the activity is a science lesson in the making. :):):):) I guess we homeschool moms try not to miss any opportunity.

For now, I suggested we try out the Ikea plastic children's tumblers we have first.

Ummi's Advice: I always try to imply to my kids that there is not only one way of doing things. We should always improvise. We don't need to BUY things / spend money to have fun. Making things up on your own is not only more amusing but also rewarding.

Trying it out

After a couple of times Lil Muallim # 1 figured out how to keep the tumblers from getting stuck inside each other.......atleast most of the times. He figured out how much pressure to use and loosed the stacked tumblers before starting afresh every time.

He tried out different sequences with the 15 tumblers we had.

5 groups of 2-1

2 groups of  3-2-1 and i group of 2-1

1 group of 4-3-2-1 and 1 group of 2-1

1 group 5-4-3-2-1 

He did, and did, and did, and did and couldn't stop :) Infact he got the others doing it too.

Lil Muallim #1 Speed Stacking

It was fun to watch Lil Muallim #1 doing it and teaching to his siblings VERY PATIENTLY Mashallah! It was so cute how he kept encouraging them

Lil Muallim # 2 Speed Stacking


Lil Muallimah Speed Stacking

 Lil Muallimah wouldn't be left behind and she tried it too... and did quite well to everyones surprise. The older Muallims were quite patient with her Mashallah and kept egging her on.

First she made her 'Tower'


And Ta Daaaaa.... she raised her arms uo\p in excitement when she was done.......


After almost  4 hours of speed stacking in between dinner, clean up, and snow shoveling, hehe 

Lil muallim commented: "This is the best past time ever for your free time!"

Guess I will be pulling this one up on him the next time he says I am bored. HA HA!!!

Timed Stacking

Mind you, the stop watch was out after 2 hours and scores were being kept. To my and his utmost delight and Abi's surprise Lil Muallim improved his score with practice. Infact in the longest sequence his time came down by more than a minute.......Mashallah!

 I am loving it cause I keep telling him we shouldn't expect ourselves to be perfect as soon as we try to do something...PRACTICE IS THE KEY.....but ofcourse who likes hearing that?

 Now with speed stacking, he WANTS to practice, so he is doing it again and again. I pray to Allah that he applies this lesson learnt so candidly, in other things too Ameen. 

Do I sense your plastic glasses coming out too?
