Games with magnets

4th classes have been learning about magnetism in Science, and to conclude the work they have designed and made inventive games with magnets. 
Starting with brainstorming ideas and working out what materials they would need, the students worked in class time, mostly in pairs,  to bring their ideas to life.  Projects ranged from using magnetism to guide actors on a stage, to various 'fishing' games and mazes, to a crane that managed to lift its own weight.
After writing their work up as a procedure, complete with diagrams, students will present the challenges and pitfalls they experienced to the rest of their class.

Building maths concepts

3rd class R boys have been having fun in maths exploring 3 dimensional shapes.  Working in pairs they have built a wide range of 3D shapes with skewers and blue tack- learning about vertices, faces and edges - and experimenting to find which shapes are the most stable.

Maths camp

On the 11th - 13th March, Eloise, Ellie, Josh and I went on a maths camp to Elanora Heights conference centre.  We had to wake up at 7:00 to go for a morning swim, then we did maths for 13 and a half hours.  We weren't allowed to go to our cabins until 9:30pm.
We did a lot of maths in that time.  We did so much that at the end of the camp I had an insane headache from all the maths.
I'm so glad that I got to go.  It was such a great opportunity and a really good experience.  I learnt so many new things, such as how to define a problem and collect and organise the data.  We also learnt to work as a team, and how to enjoy maths and make maths fun.   I am a better mathmatician now. I enjoyed it so much and I'm sure everyone else that went did too.

2nd classes' Coastal trip

Studying wet and dry environments at the Coastal Environment Centre

On Friday 8th March, all of Year 2 from John Colet went to Long Reef in Collaroy.
We went for a big walk around the rock pools. We went and saw starfish, anemones, crab and lots of limpets and oysters.  We didn't see a blue ringed octopus.
We ate our lunch on the stairs at Long Reef.  It was a hot day.  The walk was hard because my bag was heavy but I really enjoyed looking and touching the rock pool.
By Amy, 2nd class C

...We went on a school excursion to the Coastal Environment Centre at North Narrabeen.  The excursion was really interesting and fun. 
We went on a rock platform at the beach.  I saw and felt anemones.  They felt jelly like. I really enjoyed seeing and feeling all the sea creatures.
I had a great time and I would love to go again.

Buoyancy (or why did the Titanic float, then sink?)

The topic in Junior Science Club this week was buoyancy: Why do things float? Everyone tried experimenting at each of our four stations to investigate. Click  "Continue Reading"   to find out what our Junior scientists got up to at each station.

Young biologists on Safari

Our two 2nd classes are loving their science unit "Schoolyard Safari" where we investigate small creatures found in the schoolyard and our own backyards.

The children have observed worms and snails closely, drawn diagrams and now have
the worms in a worm viewer in their classrooms where they are closely observing their movements and habits. Lots of fun!

It's never too early for algebra

These are photos from our Maths lesson on Patterns and Algebra this week.  Madeleine  and Yasmine are creating AB patterns (patterns involving two variables) and recording them in their Math Journals. 
On the carpet are more complex patterns using paddle pop sticks.  Some are in 3D, showing creative thinking by the children.  An extension of this is to create patterns which can be transferred to sounds such as tapping and clapping.  These are all foundational concepts for algebra in later years.  Both 2nd class T and C did this block of work.

3rd class volcanoes

This term, 3rd Class have been extremely busy putting together Volcano Projects. This is part of our HSIE topic. Children have been given free range to create a presentation in which they must include lots of different information and facts about volcanoes. Children have also had the opportunity to make their very own erupting volcanoes which has been both messy and lots of fun! We haven’t quite got to the erupting part but very close to finishing our models, then the real excitement can happen.

The children have been so engaged in these projects. It has been wonderful to see the children co-operating, compromising and learning from one another. It has been a very successful project in many ways and a great way for some to extend themselves and be creative.

Here are some photos that will give you a sneaky peak of what we have been doing:

Fun with problems!

Many of our primary aged students have enrolled in problem solving classes after school each week.   The children certainly don’t seem to mind staying late at school, even on a Friday,  because the problems are fun to solve, yet still challenge  the children to think and use different methods to come up with answers.   

For example, they’ve designed the best possible zoo (where all the animals can get to the lake, but not all of them need to access the savannah, for example) and another, set out below, challenged the children to find the most efficient way for a farmer to transport some troublesome produce... 

Problem: a farmer has to row across a river to deliver a chicken, a sack of wheat and a fox to the other side.  The fox and the chicken can’t travel or be left together, because the fox will eat the chicken.  The chicken and the wheat can’t travel or be left together, because the chicken will eat the wheat.  There is only room in the rowboat for the farmer to row two ‘items’ across at once.  How can the farmer use the boat to transport the wheat, the fox and the chicken safely across?   (Answers involving stowing the chicken up a tree on the far side, or tying the fox into the empty wheat sack, while inventive, are not part of the actual answer!)

Communication science continued

This term 4th class learnt about communication and last week we learnt about the history of sound recording.  We listened to a portable grammophone that belonged to the teacher's  grandmother and was about 100 years old.  You wound a handle and the disk would start turning.  After that you would put the arm that had a speaker and a needle onthe disk and it would start playing music.

Plant science 101

Where does the water go when a plant is watered? Jack and Zander from 2nd class W  were very pleased to show off their class experiment for the week,  discovering for themselves how essential the functions of roots and stems are to plant growth.

The science of keeping in touch

4th class studied the telephone in Science recently. We looked at the basic inner components of a telephone.

We all got to try making a call on a “brick”  analog phone from the late 1980s. We also made simple telephones out of string and plastic cups.  Headmaster even had a go and they worked surprisingly well.

Ancient secrets of mental calculation revealed

If you know a quick way to square any number that ends in five, perhaps you’ve had some lessons in Vedic Mathematics.

John Colet School is running an enrichment course in Vedic Mathematics for children from 3rd - 6th classes.  The course focuses on extending students laterally through an alternative system of maths that has its origins in ancient India. 

The exercises and skills taught are not intended to replace students’ understanding of mainstream maths, but rather to enhance mental calculation and creative capacities.

The classes are being run as an extracurricular activity after school.  A common response from children taking part is: “Why were we not shown this before?”

5th class maths and science

5th class have been working on Geometric Patterns as well as 3D shapes in maths lessons recently. Resource maths books purchased using P & F funds helped to provide creative ideas for running these maths lessons. One lesson involved constructing geometric patterns of octagons and hexagons with a challenge of finding the way to make a certain number of shapes with the least number of toothpicks. Other lessons involved constructing 3D shapes from plasticine, drawing them and then transferring shapes to isometric views.

In science lessons we have been planting seeds in half-egg-shells to investigate whether the roots of the plants will break the egg-shells. So far none have broken through but it is early days! The class is waiting with bated breath for the first egg-shell to break. Will it be a carrot striving to break through? Or perhaps a radish or basil? Or even the mysterious borage plant? Time will tell ….  All resources were purchased from P & F funds with Mrs Moor using the cracked eggs to make staff lunches so nothing went to waste!

Our place in Space

How big is the solar system?   4th class travelled to the oval for science recently to investigate the size of our solar system.  The necessary tools were balls of different sizes (a hula hoop was the sun) marker flags and a trundle wheel to measure the distance between the ‘planets’. In our model it was 89.94m from the sun to Neptune.
