Friday 3rd April

Friday 3rd April (AKA Fun Friday!)


After today, I will not be setting you any work to do until we are back on 20th April J J We all deserve to relax and have a good rest! Myself and Mrs Zinga miss you all so much but we are all 2 weeks closer to getting to see each other again too! J


First, complete 30 Minutes on Read Theory, Day 10 of the Spelling on Purple Mash and one page of your Big Maths CGP book.

Then, please use the CGP Mark Schemes that I have written below to self-mark all of your CGP work from this week. If you haven't finished marking any previous ones, they are on the Friday 27th March web page. 

Hopefully, I haven’t made any mistakes with the answers, but if you think that I have, please let me know. If you are unsure of where you went wrong anywhere, please ask and I will help you.



As it is the last day of the term, I thought I would set some slightly different tasks to do today. The task are listed below. Please write about what you did in your Green book.


 Please, please send me some photos etc. to show me which ones you have chosen to do.



Collect all of the following items in a bag/basket. Tick off the items as you go:

  • A toy/item with wheels
  • A book with the first letter of your name in the title
  • A pair of matching socks
  • 4 things that are green
  • Something very soft
  • A toy/item smaller than your hand
  • Something round
  • A book with number in it
  • A photo of someone you love
  • An item you can see yourself in
  • An item that makes you feel cozy
  • A toy/item that has 3 different colours
  • A movie that has ‘S’ in the title



Collect all of the following items in a bag/basket. Tick off the items as you go:

  • 5 leaves that look different
  • A stick that is longer than your hand
  • A rock with spots on it
  • A flower
  • A flat rock
  • 10 blades of grass
  • Something you love to play on
  • A piece of rubbish that you can recycle
  • Something that is brown

  • Something that is very light
  • Something that needs the sun to live
  • An item smaller than your thumb
  • Something that starts with ‘M’

4. How to Grow a Rainbow.

You will need:

● Kitchen roll/paper.

● Felt tip pens.

● Two small bowls of water.

● Paper clip.

● Thread.


 1.Cut your kitchen roll into the shape of a rainbow.

 2. Colour a rainbow with felt tips about 2cm up on both sides.

 3. Attach your paper clip to the top and tie a piece of thread to it. This will give you something to hold your rainbow with.

4. Fill each small container with water.

5. Hold your rainbow with the ends slightly submerged(dipped) in the water then watch your rainbow grow!   

The Science.

A brief introduction to ‘capillary action’ Water molecules like to stick to things -including themselves. Sticking to things is called adhesion and sticking to itself is called cohesion. The fibres in the kitchen roll make lots of little holes. Water is ‘sucked’ through the holes because of adhesion. The water pressure will eventually slow down and the pressure of gravity will mean it stops moving.

5. D.I.Y. Lava Lamps.

You will need:

● Vegetable/sunflower oil.

● Vinegar.

● Food colouring.

● Bicarbonate of soda.              

● Tall glass or bottle.

● Spoon.

● Small cup.


  1. Add three spoons of bicarbonate soda into the tall glass or bottle.
  2. Fill two thirds of the container with oil-but DO NOT mix!
  3. In the small cup, add some vinegar and several drops of food colouring.
  4. Slowly add drops of your coloured vinegar into your oil/bicarb mixture and watch your lava lamp come to life!

The Science.

Oil and vinegar do not have the same density (how heavy something is) Vinegar is dense than his type of oil- that’s why it sinks to the bottom of the container.

Once the vinegar touches the bottom of the container, it reacts with the bicarb. This chemical reaction creates bubbling carbon-dioxide, which rises-these are the bubbles you see within the container.

6. Invisible Ink.

You will need:

● Lemon Juice.

● Cotton bud or paint brush.

● Cup.

● Paper.

● Hairdryer.


  1. Add about one tablespoon of lemon juice to the cup.
  2. Soak the cotton bud or brush in lemon juice and use it to write a message on your paper.
  3. Once it is dry, it will be invisible.
  4. CAREFULLY hold your paper over a hairdryer to reveal your message-try not to set fire to the paper. Get an adult to help you and make sure you have a bowl of water next to you just in case!

The Science.

The paper discolours before the rest of the paper gets hot enough to do so. Lemon juice contains carbon compounds which are colourless at room temperature. Heat breaks down these compounds and releases the carbon. When carbon comes in contact with air (specifically oxygen), oxidation occurs and the substance turns light or dark brown.

7. The Leak-proof Bag.

You will need:

● Sharpened pencils or skewers.

● A sealable bag.

● Water.


  1. Make sure your pencils are sharp before you begin.
  2. Fill three quarters of your bag with the water and seal it.
  3. Holding the top of the bag with one hand, use the other hand to push a pencil right through to the other side. Like magic, there are NO leaks!
  4. Repeat with several pencils-making sure they are pushed through in different places on the bag.
  5. Test how many pencils your bag can hold.

The Science.

The bag is made out of polymer which has lots of molecules attached together in long chains. The tip of the pencil can easily push apart the molecules.

8. Grow Your Own Hanging Crystals.

You will need:

●Two glass jars.

●Hot Water.

●Bicarbonate of soda.

●Two paper clips.

● String or wool.

● Small plate.


  1. Pour hot water into the jars and stir in bicarbonate of soda until no more will dissolve, (about 6 teaspoons). When a layer forms at the bottom of the jars, this means no more will dissolve.
  2. Tie a paper clip to each end of the piece of wool or string and place each end in each jar, so it hangs in between.
  3. Put a small plate underneath the wool between the jars.
  4. Leave the jars for a week. Crystals will begin to form along the wool, hanging down like stalactites. You may even get crystal stalagmites, forming on the plate!

The Science.

You have created a super-saturated solution. Hot water can hold more dissolved bicarb than cold water because the molecules are further apart. When the water cools, the bicarb can no longer fit in the water, so it clings to the wool. As the water evaporates, crystals form. These crystal strings get longer as more water drips down.
