  • Introduction:

Hello guys, we are a students of ESO 2. Now we gonna explain you a experiment that we did in laboratory the last week called MAKE SNOW with a diaper. Enjoy the experiment.

  • Materials:
    Diapers
    Water
    Glasses
  • Procedure:
    -First with the cotton of the diapers we do dust of cotton.

-Then we put the dust into the glasses.

-Finally we put the water into the glass with the dust of the cotton.

-And we make snow


Why we do this experiment?
Because it’s a nice experiment and all the member we love the snow because we love skiing.

  • Results:

We observe that the volume of the dust (snow) increase.

  • Conclusions:

After do the experiment, we observe that the experiment it’s difficult because do the dust of cotton it’s vey slow task.

Introduction:

Hey! We are a guys from second of ESO and the last Wednesday, 14/03/2019 we did an experiment. Our experiment was a chemical reaction called: “toothpaste for elephants”. It was a very fun experiment and we enjoyed it very much! We would repeated again!

Materials:

For the experiment we need:

  1. 30ml of hydrogen peroxide (aigua oxigenada)
  2. 15 gr of “yaduro de potasio”
  3. 20ml of liquid detergent (fairy)
  4. Erlenmeyer
  5. Bowl
  6. Test tube

Procedure:

  1. First we have to take the (15gr of yaduro de potasio) and we have to dissolve it with water in a little glass.
  2. Then we have to put in an Erlenmeyer Flask the 30ml of hydrogen peroxide with the 20ml of liquid detergent and mix it.
  3. And to finish the experiment we have to pour the “yaduro de potasio” (dissolved) in the mixture of hydrogen peroxide and the liquid detergent. This will make the chemical reaction.

(For cleaning the erlenmeyer and all the materials be careful because the foam can stain the clothes)

conclusion:

Our conclusion is that in the moment that we put de “yaduro de potasio” something happened like a chemical reaction and made this incredible foam.

We hope you liked, and we’ll like that you prove to do the experiment at home!

Last day, 16/01/2019 we made an experiment in the laboratory. We made the pH of household chemicals to determinate it. We also discover patterns involving pH that is the measure of the acidity or basicity of a solution that in our experiment, was liquids. The scale of the pH goes from 0 to 14, there are three basic resultas that are basic, neutral and acidic. When we put cabbage in to the test tubes, when then we put different liquids with different pH of acid, the color changed. The different liquids that we put in to test tubes was: coke, milk, alcohol, wine, ammonia, bleach.

El dijous 18/10/2018, a laboratori vam fer un experiment anomenat “Pasta de dents per elefants”. Aquest experiment consistia en com diu el títol, fer una mena de pasta de dents per elefants.

Abans de fer el experiment, la Mireia en va fer posar bata de laboratori, guants de goma i ulleres protectores, per precaució. Per fer la pasta vam barrejar detergent líquid, aigua oxigenada i iodur de potassi.  En ajuntar aquets tres productes va haver-hi una reacció química, i va sortir una espuma d’un color groc fluixet. Vam medir la temperatura de l’espuma amb un termòmetre i estava a 55 graus, és a dir, molt calent i per això no ens van deixar tocar la espuma.

A tota la classe ens va agradar molt fer aquell experiment, i al final de tot la Mireia ens va dir que en veritat no era pasta de dents per elefants, però que es deia així perque ho semblava.

NON-NEWTONIAN FLUID:

Who are we:

We are Martina Javier, Martina Barri, Liam Moore, Joel Culell and Júlia Lahoz.

Hypothesis:

We think that this experiment will work, because we think it’s a really easy recipe, plus, Martina has already done it at home.

Materials:

  • Cornstarch

  • Water

  • Recipient

  • Spatula

  • Purple alimentary colorant (red+blue)

Steps:

  • Put half of the pack of cornstarch in the recipient.

  • Next add some water and mix.

 

  • Repeat till the other steps till it looks like a liquid but it feels like a mass.

   

  • (optional): Finally add the alimentary colorant.

Results:


Conclusions:

It worked, the experiment was a success. It has been amazing to touch a fluid that doesn’t have a specific state (solid, liquid or gas).

Avui als Racons d’infantil i primària QUÈ, QUI, COM, hem fet tres racons: el racó dels colors, el racó del tacte i el racó d’observació.

Ens han ajudat alguns alumnes de 2n d’ESO: la Martina, la Júlia i la Martina i el cap de dia Pau. Ho han fet molt bé i ells s’ho han passat molt bé també.

Our experiment

Our experiment in the lab

Made by: Guillem Pujol, David Subirana and Oriol Vilanova

Materials:

5 Glasses

Toilet paper

Alimentari colorant, green, blue and red

FAB62898-8359-4006-89C8-072104E0C063

 

Hypothesis:

We think that the water is going to be absorbed by the toilet paper and it will bring the water to the other glass that didn’t have water.F0A8A4D6-575D-4A55-8BE6-7C91C91331EA

 

Conclusion

The experiment has been successful. The water has moved from a glass to an other and the colorantes has mixed.
