temperature?

Science 2:Can you reverse the

change?

Design & Technology 1:

Food tech –chocolate creations

Design your own chocolate bar

Science 3:Moulds – experiment with different shapes

for your chocolate bar

Design & Technology 2:

Create a package for your chocolate bars by making a net of a

3D shape.

your own font / typeface / lettering

style

Art 2:Decorate the

packaging – use your

logo and then think about the colours you use

Art 3:Create an advert poster, using ideas from ‘English

4’, but be creative to make it eye-catching.

Geography 1:Tropics / Cacao trees.

Try testing a family member with the quiz

cards

PSHE:Why is Fair Trade

important?

English 1:Follow and listen to at

least Chapter 1 of Charlie & The Chocolate Factoryhttps://www.youtube.com/watch?v=

qCuNSZjCKg8&feature=youtu.be

English 2:Inventing words, ‘Roald Dahl style’.See activity below

English 3:Winning ticket

writing

English 4:Write the text for an advert to persuade people to buy your chocolate. This may

help: https://www.bbc.co.uk/teach/class-

clips-video/english-ks1-ks2-how-to-write-a-persuasive-text/zkcfbdm

English 5:Write a set of

instructions / a recipe so we can make your

chocolate at home and taste it.

Maths 4:Willy Wonka’s maths

problems

Maths 5:Place value chocolate

mystery

Maths 3:Weight Check

Weigh your chocolate bar/s so you can write

the weight on the packet

Maths 2:Chocolate Blast

Score 1,000 points in a day to enter the chocolate draw

Maths 1:Chocolate bar areas /

multiplication

Science 1:Try to find at least 3 different types of chocolate. Place a square / piece of each (keep them the same size, so it is a fair investigation) in a small bowl / on a light plate. Place the small bowl / plate with the chocolate on in a larger bowl with some warm water. Observe closely. Do they melt at the same time? If not, why do you think that is? (explain like a scientist) Are there any patterns?

If you have a cooking thermometer, you could be really scientific and measure the temperatures that they melt at.

Some interesting videos to watch here…https://www.stem.org.uk/resources/elibrary/resource/315591/what-temperature-does-chocolate-melt

Science 2:Reverse the change!You’ve melted the chocolate (or try ice cream, or butter) – it is now a liquid. Now, how can you solidify it again?

For a challenge, try to do it without a fridge / freezer! Explain how you did it + see if you can find out what is happening to it as it turns solid again.

Design & Technology 1:• Try blending different chocolates together• Mix fruit or other ‘extras’ into your chocolate• Add a topping• Run a taste test (survey) with different designs in

your household • Act on feedback from your survey results and

‘tweak’ / redesign your product.

Science 3:Use different objects from around the house.Make a mould the correct shape you want.How can you make it easier to get the chocolate out?How would a scientist explain why the chocolate takes the shape of your mould?

https://littlebinsforlittlehands.com/chocolate-science-reversible-change-food-science/ may help.

Design & Technology 2:If possible, watch this…https://www.bbc.co.uk/bitesize/topics/zt7xk2p/articles/z247tv4Use the cardboard from old cereal boxes / delivery boxes, or nice white card if you have it, to make nets and come up with an interestingly shaped packet for your chocolate bar.

You could also try adapting an existing packet / box that is going in the bin / recycling.

Art 1:Create a font to match the name of your chocolate bar, like this one for my ‘Ice Bar’:

Maths 2:Score 1,000 points or more in a day to enter a prize draw. The child who wins will get chocolate delivered as a prize!

Maths 3:As well as measuring the weight of your chocolate bars, try checking the weights of food in your kitchen. Can you find 3 that are labelled with the wrong weight? For example, they say 350g but only weigh 345g?A reminder, if you need it…https://www.bbc.co.uk/bitesize/clips/z9kwmp3

Maths 1:Use the squares to calculate the areas of the chocolate bars.How are the chocolate bars like arrays for multiplication?How could you use times tables facts to solve these more efficiently?

See: https://www.bbc.co.uk/bitesize/topics/zjbg87h/articles/zwqt6fr if you can.

Geography 1:Chocolate (from cocoa beans grown on cacao trees) is grown in countries in ‘The Tropics’. What are Tropical countries? Where are they?What is special about them that makes these places great for growing chocolate?Could I grow chocolate in my garden? Why not?

PSHE:Watch the video of beans being harvested and read through the slides on here about Fair Trade. There is some of it that may need an adult to help you with, so if possible, watch together with someone.Why should we try our best to buy Fair Trade goods?

English 3:Great writers, like Roald Dahl, can describe and entertain in just a few carefully chosen words. In no more than 280 characters (the Twitter limit), explain how you would feel and what you would do if you’d won a trip to a magical place. Any letter, piece of punctuation, or a space counts as a character .

Maths 1

How can you use multiplication to help you calculate these

without counting the squares?

Hint – ‘arrays’

Challenge!

English 2

Invent your own words to describe…1. Amazing sweets and chocolates

2. Children 3. Teachers

4. Disgusting foods

Trade Not Aid

Established in 1992, the Fairtrade Foundation aims to give small-scale farmers a better deal, offering families in rural communities a stable income and enabling them to plan for their future.

Buying items with the Fairtrade mark means you are helping to support farmers and workers around the world, giving them a fair price for their products.

You!

The People

Meet some of the farmers who produce the cocoa that

makes your chocolate. They belong to a cooperative,

which means they pool or gather their resources and

work together.

Many cocoa farmers are from Ghana in West Africa.

Around 65,000 farmers belong to the Kuapa Kokoo

cooperative. Together, they grow, farm and harvest

cocoa before selling to the Fairtrade organisation for a

guaranteed fair price. They even own shares in Fairtrade

chocolate companies, giving them greater control over

their own futures. They are proud of their work. The

motto of Kuapa Kokoo is ‘Pa Pa Paa’, which means ‘best

of the best’.

The Trees

Cocoa trees grow to be five metres tall. They reach maturity in between three and five years, which is when they begin to produce the valuable cocoa pods.

Thousands of tiny white flowers appear on the cocoa tree. Between 20 and 30 of these develop into pods.

Strangely, the pods can grow on the branches or the trunk.

The Pods

The cocoa pods are roughly 35cms in length and are shaped like rugby balls. The pods are cut open with a machete or long knife. Inside, protected by a white fleshy pulp, are 30-40 cocoa beans.

Cocoa pods can be harvested twice a year. They start off green and turn yellow as they ripen.

The Trade

Once dried, the cocoa beans are packed and taken to the village.

The recorder is in charge of weighing and paying. Farmers are elected to this important position and are trusted to be fair. Before fair trade, many companies would cheat the farmers by giving a false weight and paying poorly.

Why do you think community projects are important?

Now, at cooperatives such as Kuapa Kokoo, fair trade means a set price and a social premium, which provides money for community projects such as clean water wells and schools.

The Factory

After weighing, the cocoa beans are loaded onto trucks and taken to the port where they travel on to European fair trade chocolate factories.

The cocoa beans are roasted, then winnowed to get rid of any shells before being turned into cocoa butter and cocoa liquor.

Cocoa liquor, cocoa butter, milk, sugar and vanilla are mixed for several days in large vats. After testing for consistency and flavour, more ingredients may be added before moulding, wrapping and packing.

The Shop

The journey from cocoa bean to chocolate bar is complete. Now it’s down to you, the customer, to choose which type of chocolate to buy.

What would influence your decisions? How would you respond to the these customers?

Bright colourful packaging makes it look appealing.

I prefer to buy Fairtrade products.

The taste! I’m prepared to pay a little more for a

good taste.

As long as it’s cheap, I’ll buy it.

I don’t think about where

it’s from.

I like to know who made the product.

It’s important that cocoa

farmers get a fair deal.

I like to be kind to the environment.
