ELECTRIC CIRCUITS

 During Januray, students of 6th course have studied the topic related to energies and electricity. They have done many activities but one of the most interesting has been the electric circuits.

The task was about making an electric circuit and to introduce it to the rest of the class. The results were amazing.

Congratulations for all the works!!!! We really enjoyed with this activity.

In this link you can watch the electric circuits:

ELECTRIC CIRCUITS

A CHEMICAL ENGINEER

                                                      

Last Tuesday, January 16, an engineer named Antonio (the father of a student known as Clara) came to the school Jose Maria de la Fuente to talk with them about energy. He knew many things because he has been working with energy for 20 years.

First, he warned us that when we saw warning signs we could not touch him because we could electrocute. Then he told us different forms of energy there and explained them one by one and very clearly.Then he went into more detail on the subject he deals with the most: the mills.

When he explained it to us we were surprised that mills could be installed in the water! He also explained that the mills were put in places where there was a lot of air.The mills transform wind energy into electricity with a generator. The mills normally measure 334 meters and is larger than the Eifell Tower.

Entering the world of energy that tests water we can discover that when the water impacts creates mechanical energy and people working in this type of energy installed a turbine next to a generator so that when the mechanical energy of the water rotates the turbine which will produce more mechanical energy than going to a generator , which will transform mechanical energy into electricity.

In my opinion I think that the talk was very interesting and funny because he prepared some games and he explained very clearly.

EXPERIMENTS IN THE 6th LEVEL

 EXPERIMENTS IN 6th A

"Volcano on fire in the classroom"

With some spoonfuls of vinegard and bicarbonate of soda, Amelia has created an erupting volcano inside the classroom. After mixing these substances carbon dioxide is formed, forcing the content of the bottle to come out of it, making the same effect as real volcanoes.

Video of the experiment

"Sand that doesn't get wet"

After sprinkling with some waterproof spray a small quantity of sand and waiting for a couple of hours, Candela has achieved that this sand doesn't soak in water!

   

Video of the experiment

"Rain of colours"

In this experiment, Iria has made a wonderful colourful rain in a jar of water. Mixing water, oil and colourant has demonstrated how different densities can produce this incredible effect. First, you have to mix water and oil. As it is known, the oil has more density and stays on top of a jar and when you add the colourant to the mix, these start to fall down little by little.

  

Video of the experiment

"Pepper and soap"

Paula has shown us how important is a good hygiene when cleaning too. Mixing pepper and cinamon with water on a plate, she has shown us the chemical properties of washing-up liquid and how dirt run away from it they are in contact.

"Water that doesn't fall"

With a glass recipient with water, a tight and an elastic band, Eugenia has tried to make water fall through the tight but it didn't fall (at the beginning, later it has been falling little by little). Thanks to the surface tension of water itself, the surface of water ends up acting as an elastic membrane blocking the content of the recipient from pouring.

                                              

   Video 1   Video 2    Video 3                                                                   

EXPERIMENTS IN 6th B

"Floating Candle"

Alberto has shown in class the force of the atmospheric preassure with a glass, a plate, water and a candle. Once the candle is lighted, it is consuming all the oxygen, so the preassure inside the glass starts to be lower and the water level rises.

"How to introduce a egg in a bottle"

When the air inside the bottle is heated, the molecules, or tiny air particles, inside the bottle spread out, increasing air pressure. As the air in the bottle cools, the air pressure decreases. The greater outside air pressure pushes the egg into the bottle. Blowing into the bottle raises the air pressure again.

This is the experiment that Jimena and Lucia M showed in class, that time didn't work properly but they explained and all had a great time.

"The egg that bounces"

Laura E.  introduced an egg in vinegar for few days. When she took out the egg we could see how it bounced like a ball until it broke on the floor.

"A Rainbow"

Samuel and Germán show us how to make a rainbow coloring a kitchen paper and putting it in two glasses of water.

"The Volcano"

Our students Mª Isabel and Lucia P. show us this chemical reaction simulating the eruption of a volcano.

1. Combine the vinegar, water, dish soap and 2 drops of food coloring into the empty soda bottle.
2. Use a spoon to mix the baking soda slurry until it is all a liquid.
3. Eruption time! … Pour the baking soda slurry into the soda bottle quickly and step back!

 EXPERIMENTS IN 6th C

"Jumping egg"

Rocío has shown us how you can become an egg in a bouncy item after sinking it in vinegard for two days. The acid properties of the vinegard and the calcium carbonate of the shell creates a chemical reaction that disolves this shell. Thi does not mean that the egg can't be broken              

                                     

Video of the experiment

"Solid viscous cornflour"

Laura has created a viscous compact substance simply by mixing four spoonfuls of cornflour with a few mililitres of water. This mixture doesn't moisten the cornflour, it has got the opposite effect: when you pressure it, it becomes more viscous. In those areas where you apply pressure, the flour particles become compact, catching water particles among them, and this mixture becomes temporarily in a solid material.

"Rainbow of colours, egg in a bottle and red inversed rain"

Sergio has shown us three short and curious experiments. First, he has created a rainbow separating the coloring of some sweets just with a little water. After that, he has introduced a baked egg in a bottle with some fire at the bottom. This happened because the need of oxygen has made the pressure of the bootle to pull the egg to the bottom. And finally, with some liquid colourant, water and some fizzy pills has created a rain of red colour because of the effervescence of the gas.

                                                       
                               

"Pepper and soap and inflated balloon"

Iván has demonstrated two easy and interesting experiments. First, removing dirt in a bowl with some washing-liquid soap in a finger and then, introducing bicarbonate in a bottle and some spoonfuls of vinegard in a balloon has achieved inflate the ballon placing it over the bottle. This mixture creates carbon dioxide that inflates the balloon.

SAFETY FOOD IN JMF

 SAFETY FOOD IN JMF

Last Monday, October 9, Vanesa (Jimena’s mother) came to   our   school   to   talked   about   safety food.

All students of 6º of Primary were in our class (6º A) participated Jimena, Lucía M, Lucía P, Alex, Paula and Samuel.

All students of 6º of Primary in the workshop

Vanesa projected a Power Point about Food Bacterias and Foodborne Infection.

   Vanesa talked about what bacteria need to grow:

1.              Nutrients

2.              A good temperature (between 5ºC-65ºC)

3.              Humidity (Vegetables, meat and fish need to be preserved in fridge and cereals, flours, rice,cookies,...can     be     preserved     at   ambient temperature)

Vanesa explained us three types of infections: Salmonelosis, Botulims and Staphylococcus Aureus and how we can prevent them.

For example, to prevent salmonelosis, we need to place well the fridge: raw food at the bottom, cooked food at the top and protect the food.

Vanesa also talked about labelings parts: company brand, the name of the food, list of ingredients, allergens, shelf life, store conditions, nutritional information, date of expiry,...

After that, Vanesa gave us ... real bacteria!!! There were in a specific plastic box.

And finally, some kids dressed up as scientists and Jimena took bacteria of their hands, put bacteria in a specific box and now we are expecting that bacteria grow.

Jimena caught bacteria from hands

The workshop was very interesting and funny.

I learned a lot about how to use and keep aliments. It was very funny when Jimena caught bacteria and we are waiting to see bacteria.

I want to repeat!
