water pollution

Worksheet 10

We checked if the seeds can grow in diferents concentrations of different polluting water (in distilled water, polluting 0.1M, polluting 0.01M and polluting 1M) . The pollutings are: NaCL, NH3 and NaOH.

We did this experiment:

We took 10 ml of the polluting solution and put them in a 100 ml test-tube.
We filled it with distilled water up to a 100 ml.
We poured this solution into a new bottle labeled "polluting 0.1".
We maked this procedure with the other pollutings.
We put paper in every petri sheet.
We placed 10 seeds in every sheet.
We put 15 ml of every concentration in every sheet and wait a week.

Last day we make soup with reciclate oil.

We make this soup with this order.


1.- We put 25 ml of oil in one erlenmeyer add 10 ml of destilate water.


2.- We waight 4,5 g of Na OH and put on a new erlenmeyer.(erlenmeyer 2)



3.- We take 15 ml of water and put in erlenmeyer 2.



4.- We put this mix and we wait a week.

WORKSHEET 6



The last day we:

-Verify that the city creates a micro-climate inside the general inside the general climatology of the area.
-Study an example of city micro-climate.
-Use the measuring instruments in its proper way.
-Encourage the observing and deducing abilities of the students.

We mesure:

-The temperature with a thermometer.
-The relative humidity. with a hygrometer.
-The wind speed with a anemometer.

We observate that the temperature is higher down and in up is lower because the floor absorve the energy of the sun and the wind up refresh.

The wind speed of casp is lower of the roof.

Gran Via Pau Claris Casp

WORKSHEET 4

On Tuesday we counted the number of cars, pedestrians,buses, taxis, bikes,motorbikes in three streets around the school.
There are the questions of the worksheet 4.

Gran Via is most wide than Casp and Pau Claris. In Pau Claris they pass more cars than in Casp but in Gran Via there are more cars than in Pau Claris. Pau Claris it's a comercial street.

MOBILITY AND WAYS OF TRANSPORT

WORKSHEET 3

This is a image of Casp Street.

We mesure, the width of the streets Casp, Pau Claris and Gran Via.

These are the average of the measures of the three streets of the around of our school

The most wide is Gran Via because is a main street and also the most lengh

We mesure our footstep and we multiply it by the number of steps, and we mesure the average adding all the mesures of the other students and dividing them by the numbers of resaults.
