EGG & VINEGAR

WE NEED 

• An egg .
• Some vinegar.
• A glass.

   
HOW TO DO IT

1. Put  the egg in the glass .
2. Add some vinegar to the glass.
3. Let it rest four two or more days.

PREDICTIONS

RESULTS



The shell of the egg is gone! Why? Because it is made of calcium carbonate and if we add vinegar this calcium changes its composition creating small particles of calcium, the vinegar becomes dark brown, and CO2 bubbles that we see in the glass.
As the shell is gone, the vinegar can enter the next part of the egg and it changes its size, it is bigger than a normal egg.

EGG'S SHELL (CALCIUM CARBONATE)

VINEGAR

=

CALCIUM + CO2 (BUBBLES) + BIGGER SIZE

OUR OPINION

We like this experiment because is funny and interesting.

THE EGG WHITE

WE NEED

• An egg.
• A fork.
• A  bowl.

HOW TO DO IT

1. Break the egg.
2. Separate the egg white and the yolk 
3. Put the egg white on the bowl.
4. Beat the egg white using the fork.

PREDICTIONS




RESULTS

The egg white contains a lot of proteins that are organized in a natural way. When we beat the egg white we are breaking these proteins, a process called denaturalisation, that's why the egg white changes its colour. At the same time, the proteins add air to their organisation creating bubbles and increasing its volume.

OUR OPINION

We like this experiment!!!

THE COLOUR MOVEMENT

WE NEED

• Three glasses with water
• Paint (red, blue and yellow)
• Paper serviettes

HOW TO DO IT

1. Fill the glasses with water and add red, blue and yellow paint.
2. Roll up two paper serviettes.
3. Put the paper serviettes in the glasses like this.

PREDICTIONS

RESULTS

The process that we can see with this experiment is called capillarity. This is a characteristic of the liquids that makes them go up and down a capillary. It is also the way in which plants absorb the water and the components dissolved in the water to "eat".
The colours aren't mixed up because the second part of the serviette is already occupied by the liquid of the other colour.


OUR OPINION

We like this experiment because is funny and a very interesting thing.

THE COKE'S MYSTERY

WE NEED

• A bottle of Coke
• Salt

HOW TO DO IT

1. Predict what would happen if we add salt to a bottle of Coke.
2. Go to the playground.
3. Stay in a big circle around the bottle of Coke.
4. Let the teacher add salt to the bottle.
5. Observe the results. What has happened?

PREDICTIONS

RESULTS

The coke has got carbon dioxide (CO2) dissolved. Carbon dioxide can "scape" from the coke if some bubbles are "created". To create bubbles, we must separate water molecules (H2O). The composition of the salt helps the water molecules to separate and to liberate the carbon dioxide by creating bubbles.

COKE (CO2 + H2O)

+

SALT - breaks H2O - CO2 scapes

=

GAS BUBBLES

MY OPINION

I liked this experiment and I want to do more experiments with the girls. I hope that next day their behaviour will be better and that we will have a great time learning science!

WELCOME BACK!

Hi, girls!

How were the Christmas holidays? Did you have fun with your family and friends?

During the first term, we worked around ICT skills, which means Information and Communicative Technology. 

This second term we are going to continue with ICT skills because we have a new blog!

Otherwise, this second term is about SCIENCE.

And this is our new Science Blog. Do you like it?

How the classes of the Science term are going to work:

• Listening to a SCIENCE SONG
• Looking at the report on the blog.
• Worksheets: material needed + instructions.
• Predictions about the experiment.
• A changing science reporter: take photos + update the blog.
• Doing the experiment.

The AIM is to know more things related to science but in English, of course!

Do you like doing experiments?

Do you know any experiment that we can do in class?

Let's see what is the first experiment... !
