North West London Jewish Day School

Events Coming Up!

This month is the launch of our monthly home-school science activities. See below for April's edition. Participation will earn your child science points. Collect them all and a science adventure awaits! 

Quantum Theatre is coming to do a Science show on the 19th April. We can't wait to end the term on a science high!

In recognition of our excellence in Science we were awarded an ENTHUSE bursary this year. We have been working closely with a Science consultant in order to continue to promote outstanding Science provision.  

We are so excited for the Year 6 Science Fair which will be taking place after SATs; Timetable and more information to follow.

In the Summer Term, there will also be the opportunity for Year 6 students to undertake a CREST award: these widely recognised awards give children the opportinity to explore real-world science. technology, engineering and maths projects in an exciting way. CREST is a UK award scheme that recognises success and enables students to build their skills and demonstrate personal achievement. It is student led which means that young people take ownership of their projects and choose to undertake them in areas they enjoy or see as relevant. 


Science Home Challenge - June/July

Inspired by the Year 6 Science Fair, this month we will be making Non Newtonian Fluids! Thank you to Ruby, Annabel, Maya and Joseph for sharing this exciting experiment with us.

Non-Newtonian Fluids

You will need;

1/4 cup of water, 1/4 cup corn starch, mixing bowl and newspaper

What to do: 

1) Place a sheet of newspaper on the table and put the mixing bowl in the middle 

2) Put 1/4 a cup of dry cornstarch in the bowl

3) Next, add about 2 tablespoons of water to the corn starch and stir slowly

4) Continue to slowly add the water to the mixure, whilst stirring

5) Add water until the corn starch acts like a liquid when you stir it slowly. When you tap on the liquid with your finger it shouldn't splash but will become hard. If your mixture is too liquid, add more cornstarch. 

6) Scoop the cornstarch mixture into your hand and work it into a ball. As long as you keep pressure on it it will stay solid. Stop rubbing and it 'melts' into a puddle in your palm!

7) Have fun and play with your mixture. Can you work out why it behaves like this? 

8) Remember to send pictures to Mrs Halter ( and Miss Cohen (

Science Home Challenge - May

One of the best ways to inculcate a love for science in kids is by doing hands on activities. This is the basis for our Home-School Science Challenges and is reflected by our Schools Science Principles (see below).

Lemon Foam Eruptions 

You will need:

Clear hand soap, baking soda, warm water, citric acid or lemon juice*, plastic cups, food colouring. 

You may want to do this experiment in a tray or outside. It will get messy!

*(eruptions will be more dramatic with citirc acid although lemon juice will work. Citric acid can be bought at the supermarket and is a safe, naturally occuring acid).

What to do: 

1) Fill plastic cups with clear soap, warm water and a few drops of food colouring

2) Add a couple of scoops of baking powder to each cup

3) Next add a couple of spoons of citric acid powder or some lemon juice. Mix to create a light fluffy foam!

4) The more citric acid you add the more foam you will create. 

5) Have fun and play with your foam.

6) Send a photo of your experiment to Mrs Halter ( or Miss Cohen (

Science Home Challenge - April

The Exploding Lunch Bag

You will need:

One small zip lock sandwich bag, baking soda, warm water, vinegar, measuring cup and a tissue 

What to do: 

1) Go outside

2) Put 1/4 of a cup of warm water into a bag

3) Add 1/2 a cup of vinegar

4) Put 3 teaspoons of baking soda into the middle of the tissue

5) Wrap the baking soda into the middle of the tissue by folding the tissue around it

6) You will have to work fast now - partially zip the bag closed but leave enough space to add the baking soda packet

7) Put the tissue with the baking soda into the bag and quickly zip the bag completely closed

8) Put the bag on the floor and step back. The bag will grow and grow until it EXPLODES! 

How does it work? 

The baking soda and the vinegar mix and a chemical reaction occurs. Cardon dioxide is formed which is a gas. Gases need lots of room and spread out to fill the bag. As the carbon dioxide spreads out the bag can no longer hold it and it pops! Is this a reversible or irreversible reaction? How do we know? 

Make it an experiment:

Are you feeling like a super scientist? Make this demonstration into an experiment by answering these questions:

1) Will using different temperatures of water affect how fast the bag inflates?

2) How much baking soda will create the best reaction?

3)Which size bag will create the fastest pop? 


Carry out this demonstration or the following experiments at home and bring in pictures of you carrying it out to achieve your 'Chemical Reactions' certificate. Collect all the certificates to go on a special science adventure. 


The Science Committee

North West is proud to have its very own Student Science Committee which has been organising events throughout the school. Look out for the Science Committee report coming to this space soon. 

Our Science Principles:

At North West we believe that….


  1. Science should be FUN! Teachers should have positive attitudes to science and share these with children. Children should know that anybody can be a scientist and think, discover and invent like a scientist.


  1. Inductive learning is important. It is vital for children to explore and find out things for themselves BEFORE instruction from the teacher.


  1. Science should encourage and cultivate higher order thinking through questioning and experimentation. Children should initiate learning, coming up with their own questions and ways of investigating. Children should learn to think like scientists.


  1. Science should be hands on and children should have access to a wide range of activities and resources.


  1. It is important to work with others. Discussing our thoughts with others allows us to share ideas and develop our own knowledge.


  1. Children should always know WHY they are learning something and its real world importance.


  1. Children should understand that science is important in every aspect of life. This is reflected in strong cross-curricular links.


  1. Children should have regular extra curriculum trips, workshops, science days and assemblies as well as access to science clubs in order to extend their science learning.
Science Day

In February, we had an amazing Science Day with the Science Boffins! A whole-school assembly was followed by workshops and activities such as: slime making, lava lamp creating and making and eating edible blood. A massive thank you to Mrs Gilbert, Mr Halfin, Mrs Eppel & Mrs Feigenbaum for their incredible workshops.

Tu Bishvat Recycling Day

This year Tu'Bishvat was linked with Science Recycling Day. We planted trees, made recycled paper, paper mache bowls and made our own videos to promote recycling in the school. We also made beads and photoframes from recycled paper and learnt about different artists that use recycled materials to create beautiful sculptures. Then we made our own!
