5 experiments

Dear parents and guardians Through play, children develop different cognitive skills. Scientific studies show that when we are having fun or making discoveries during an experiment, a neurotransmitter called Dopamine is released.

Dopamine is known to be responsible for feelings like motivation, reward and learning and that’s why experiences are related to positive feelings. So, if learning is a positive experience, it will stimulate the brain to develop various skills.

Therefore, Science4you aims to develop educational toys that combine fun with education by fostering curiosity and experimentation.

Find out below which skills can be developed with the help of this educational toy!

1. The science of magic and potions 1.1. Alchemy Alchemy is a secret and mysterious ancient practice created in the middle ages and adopted until the 17th century. Many historians describe it as the medieval study of chemistry, while others theorise that it was pure magic.

Initially, alchemy aimed to transform common metals into gold, such as lead and copper. This transformation would only be possible with the help of a mythical substance – the “philosopher’s stone” – which would also act as the elixir of life, making whoever found it immortal.

Its practitioners, alchemists, combined chemical techniques and philosophical concepts in their creations. Furthermore, they believed in the existence of four basic elements:

FIRE

AIR

EARTH

WATER

DID YOU KNOW...

Scientists have since discovered how to turn an element into gold?

Glenn Seaborg was an American scientist who, in 1980, discovered how to turn a small amount of bismuth (Bi) into gold in a nuclear reactor.

However, obtaining gold in this way is more complex and expensive than extracting it from mines or recycling it.

Alchemy was vital for developing modern-day chemistry and the discovery of many of the chemical elements.

Today 118 chemical elements are known and listed on the famous Periodic Table.

PHILOSOPHY studies human thought

CHEMISTRY studies the substances

Little wizard, can you imagine how today’s chemistry will be seen in the eyes of scientists of the next millennium?

1.2. The chemistry behind the magic If you think about it, chemical reactions are like fantastic magic potions.

Stop by the lab to learn more about chemical reactions and the amazing effects you can get when you mix different substances!

What is a chemical reaction anyway?

Chemical reactions involve the mixing and interaction between different substances. The substances that react are called reactants, and any substances formed by this reaction are called products of the reaction.

Reactants

All substances are made up of molecules, which in turn are made up of atoms. An atom consists of a nucleus, which comprises protons and neutrons, and electrons that circulate around the nucleus, creating the electron cloud.

Products of the reaction Proton (+) Electron (-) Neutron

2. Magical potions classes 2.1. The lesson of Master Know-it-all

Hello little wizard!

Are you looking forward to your first potions class?

Master Know-it-all is the oldest inhabitant of the Village of Magic and its only wizard. He possesses a large and ancient potions book in which he writes all his recipes in invisible ink. One of his favourite potions is the bubbling foam.

POTION 1 Bubbling foam What will you need?

Material included in the kit:

• Sodium bicarbonate

• Blue colouring

• Potions tube rack

• Wooden stick

ATTENTION: When you finish the experiment, dispose of all foodstuff used during the same.

Steps: 1. Assemble the tube rack and place the three test tubes inside it.

2. With the small measuring cup, measure 3 millilitres (ml) of sodium bicarbonate and distribute them equally between the three test tubes.

3. Add one drop of liquid dishwashing detergent to each test tube.

4. With the Pasteur pipette, add 4 drops of blue colouring inside each test tube.

• Pasteur pipette

• Small measuring cup

ATTENTION: ask an adult for help.

• Test tubes with cork stoppers

Extra material: • Liquid dishwashing detergent • Vinegar

5. Measure 10 ml of vinegar with the small measuring cup. Distribute it equally between the three test tubes.

6. If needed, use the wooden stick to mix the content of the test tubes.

What do you think of your amazing coloured foam?

MAGIC CHALLENGE: Use different amounts of vinegar and sodium bicarbonate. Did you manage to create even larger foams ?

What happens?

The acid in vinegar (acetic acid) reacts with sodium bicarbonate, which is a base, and an acid-base chemical reaction occurs. In this reaction, gas is formed, carbon dioxide (CO2). The release of CO2 in the detergent bubbles leads to the formation of a large amount of foam.

ATTENTION: ask an adult for help.

POTION 2 Invisible ink What will you need?

Material included in the kit:

• Test tube with cork stopper

• Pasteur pipette

ATTENTION: When you finish the experiment, dispose of all foodstuff used during the same.

Steps: 1. Squeeze half a lemon into the measuring cup.

2. With the Pasteur pipette, add a few drops of water to the lemon juice.

Your invisible ink is ready!

3. Place the test tube in the potions tube rack and add the ink you have prepared.

• Small measuring cup

• Potions tube rack

Extra material: • Water • Lemon • Air dryer • Paper sheet • Cotton swab (or brush)

4. Dip the swab (or brush) in the ink and write a message on the sheet of paper.

Wait for the ink to dry.

5. To find out your secret message, ask an adult to help you and ask them to move a hairdryer closer to the sheet of paper.

What happens?

Despite its yellowish colour, lemon juice is practically transparent. So after you let the juice dry on the paper, it becomes invisible. Most fruit juices have carbon compounds in their composition. At room temperature, these compounds are absorbed into the fibres of the paper.

The hot air from the hairdryer breaks the molecular bonds in the paper and causes it to release carbon. In turn, the carbon reacts with the oxygen in the air in an oxidation reaction, which darkens the substances. This is why the lemon juice darkens and becomes visible on the paper.

Your secret drawing has been unveiled!

DID YOU KNOW...

The oxidation reaction often occurs in fruit and vegetables?

When you cut into these foods, the normally trapped inside enzymes are exposed to oxygen.

The interaction between the enzymes and oxygen causes the food to oxidise (brown).

2.2. A visit to the night fairies

At night, the village fairies use an amazing potion of colour transformation to camouflage themselves.

POTION 3 Colour transformation What will you need?

Material included in the kit:

• Test tubes with cork stoppers

Welcome!

It’s so nice to finally meet you, little wizard! We have a fantastic potion to show you. Shall we begin?

ATTENTION: ask an adult for help.

ATTENTION: When you finish the experiment, dispose of all foodstuff used during the same.

Steps: 1. Ask an adult to prepare the red cabbage water.

Put a sliced red cabbage leaf in a bowl and pour hot water.

Wait for half an hour. Using a colander, filter the liquid into a cup and leave it to cool.

2. Place the three test tubes in the potions tube rack. Use a marker to label the tubes A, B and C. 3. Add 10 ml of cabbage water to each tube using the small measuring cup.

• Small measuring cup

• Sodium bicarbonate

• Potions tube rack

• Pasteur pipette

Extra material: • Hot water • Red cabbage • Vinegar • Bowl • Marker • Colander • Cup

What did you think of this magical colour transformation?

The pH is a property of all substances to classify them as acidic, neutral or basic. In this experiment, red cabbage water acts as a natural pH indicator. In the presence of an acid, such as vinegar, it shows a pink colour. In the presence of a base, such as baking soda, it turns blue.

2.3. Up in the village sky with the witches If you keep an eye on the starry sky of the Village of Magic, you can see bursts of colour against the blue background. The witches are responsible for this magic show.

With their flying brooms, they leave a colourful trail wherever they go.

Learn how to recreate this magic with the fireworks potions and the dance of colours!

Look who it is...

POTION 4 Fireworks

the new village wizard has come to pay us a visit! Are you ready to start this colourful adventure through the village sky?

What will you need?

Material included in the kit:

ATTENTION: ask an adult for help.

ATTENTION: When you finish the experiment, dispose of all foodstuff used during the same.

• Pasteur pipette

• Small measuring cup

• Blue colouring

Extra material: • Sheet of paper • Water • Cooking oil • Clear cup

Density =

Mass Volume

Steps: 1. Fill half of the cup with water.

2. Add 50 ml of cooking oil to the clear cup using the small measuring cup.

3. Using the Pasteur pipettes, carefully put a few drops of colouring into the cup.

4. Finally, cover the cup with the paper sheet.

DID YOU KNOW...

Density is one of the most studied chemical properties?

Density is the result of dividing the mass over the volume of a body.

Watch closely what happens in the cup!

What do you see?

What happens?

Oil floats on water’s surface because it is less dense than water.

Initially, the drops of dye are trapped in the layer of oil, but slowly they sink. They dissolve when they reach the water, creating a firework’s fantastic effect!

A drop of water is heavier than a drop of oil of the same size, so we say that water is denser than oil.

ATTENTION: ask an adult for help.

POTION 5 Dance of colours What will you need?

Material included in the kit:

• Pasteur pipette

• Small measuring cup

• Blue colouring

Extra material: • Liquid dishwashing detergent • Fat milk • Toothpicks • Deep plate

ATTENTION: When you finish the experiment, dispose of all foodstuff used during the same.

Steps: 1. Put a bit of milk in the deep plate, about 3/4 of the capacity.

Let the milk rest for a few minutes.

2. Using Pasteur pipettes, add a few drops of blue food colouring to the milk.

Make sure that the drops are on the surface and away from each other.

3. Put some liquid detergent in the small measuring cup.

Dip the tip of the toothpick into the detergent.

4. Place the toothpick, with the detergent, in the middle of the drops of colouring.

DID YOU KNOW...

Is it the high surface tension of water that allows insects to walk on it?

Common pond skaters are semi-aquatic insects with long, hairy legs that allow them to spread their weight over a wide area and move on the water’s surface.

14

Surface tension is a property of liquids that holds their molecules together at the surface, resembling a membrane.

Image 2. Surface tension and forces of attraction between water molecules.

What happens?

When you put the colouring agent on the surface of the milk, they don’t mix. However, if you put the toothpick with detergent on the drops of colouring, they move apart and create an explosion of colour! This happens because the detergent breaks the bonds between the milk molecules and breaks the surface tension, causing the molecules to mix, as you observed!
