Innovative Investigations: Block and Tackle

DATE: 22 Zilhijjah 1433/8 Nov. 2012

Block and Tackle

AIM:
To build a simple block and tackle and a pulley with hangers and investigate how they work and which is easiest.

load; plasticine

MATERIALS:
- 3 coat hangers
-  plasticine
- tape
- scissors
- pencil
- paper cups


METHOD:

cup holding load

First we used the paper cup and yarn to make a bucket to hold our load.

Then we made the Block and Tackle with two hangers, some yarn and tape; we tied one end of the yarn to one hanger and taped it in place. Then we wound the yarn around both hangers and held on the the other end of the yarn to pull. The bucket was attached to the lower hanger.

The second pulley was made by attaching the bucket to one end of the  yarn and looping the other end over the curve of the hanger.


RESULTS:

Block and tackle in action

load up

simple system pulley using a hanger

OBSERVATIONS:
1.Which pulley system worked better?
The simple pulley.

2.Why?
It could be pulled more easily.

3. Did both pulleys need the same amount of force to work?
No, the block and tackle needed more force to move (it was difficult to use too).

 4. Which needed more force?
The Block and Tackle.

5.Why did it need more force to lift the load?
The yarn had to move over more distance to work and had to the lower hanger as well.

Creative Characters (Bookworm Club Competition)

Our Bookworm Book Club is currently reading "Charlie and the Chocolate Factory". Once the first four lucky golden ticket winners were revealed in the book, our Book Worms were asked to write about a fictitious child who would fit in with the first four nasty winners and tells us how the child found the ticket. They were given a week to prepare for the competition.

HBAP (7yrs) was very excited, she brought out a white board and marker and asked Ummi to help write out her thoughts. She first considered writing about a child who played too much cricket and the following day changed her mind and thought out a story about a boy who didn't like to bathe. She then asked Ummi to write it out so that she could copy it on to paper. She then wrote it out twice to make it neat, still not satisfied with her own handwriting she asked Ummi to write it out.
This is HBAP's story in her own handwriting:

TED KHAN

It continues-One day his parents said they would give him money to buy chocolate if he had a bath. He washed his hands and face with soap, and they gave him the money. Then he went to the chocolate shop and he bought a chocolate. He went home and he opened it and he saw a golden ticket inside.



MBAP (9yrs) decided not to write anything because he felt he couldn't possibly win, but was quick to suggest stories for others to write, with some persuasion he finally put together a story just before the club session began.  His story:

JESSE MEANIE

Jesse was an only child who did not know how to share. When his neighbors play cricket and their ball flies into his house he takes it and hides it in his sleeves and tells them it did not come there .When he plays with them and gets out he stops playing and goes whit his ball so no one else can play. When Jesse heard about the golden ticket he bullied small children to give him their chocolate .once he found a ticket he left the little children alone.           

IBAP (11yrs) eagerly put his story together and wrote it out without a fuss Masha'Allah!

IBAP's Story:

PETER   POSTOPIA

Peter Postopia loves his PSP. He plays on it all day long. Even when he wakes up he plays on his PSP while his mother feeds him breakfast. At school when his teacher is checking other children’s work, he uses it under his desk. Peter plays with it till he falls asleep so it stays in his hand while he is asleep. When he heard about the golden tickets he started eating chocolate while playing on his PSP, till one day he found a ticket. Peter then stopped eating chocolate to concentrate on his games.

After all the club members had presented their stories a secret ballot was carried out to ascertain the competition winner; Masha'Allah HBAP won! She received a Hajj activity book as a prize.

Unusual Pics

Alhumdulillah our Hajj trip (Abbi and Ummi's) was a smooth one. There was much to tell the children when we got back. While there we bought some books with beautiful pictures of the various important locations of Makkah and Madinah, Alhumdulillah so we took some photographs of those things we wanted to share with the children other than those in the books:

The buses used at the airport

canopies at the waiting area outside the Hajj terminal, Jeddah

  

We were provided with metal hooks to attach onto the tent walls and then hang up our bags (Mina). For many of us short sisters this was out of reach, and a safety hazard as we slept just under the hanging luggage.

Subhan'Allah there was much to discuss with the children, the Hajj was a test of patience and tolerance as well as physical endurance. It gave us time  to reflect, appreciate the things Allah SWT has blessed us with esp the things we take for granted and made us aware of our shortcomings as well. It was a real Learning Live experience and we make dua that Allah SWT will forgive us and accept our Hajj. Aameen.

Newsflash: BAPs Update

A few updates to share Masha'Allah:

-  Masha'Allah. Role Model Institute had its annual  Hifz competition where ABAP (13 yrs) was proud to have his Dada accompany him, Masha'Allah. ABAP (13yrs) place first position in his group. He received several vouchers to a nearby bowling alley/ restaurant where he and his family enjoyed a night of fun.

- Alhumdulillah QBAP (12 yrs), after attending for a week and preforming Istikara, has decided to attend RMI for hifz .

- Subhan'Allah ABAP has just completed his 11th para (juz 20).


We are grateful that Allah SWT has guided our elder two sons to make the decision to do Hifz and  may He make it easy for them, accept it from them and reward their efforts. Aameen.
