食肆..
我地係食肆出面排放油污下擺放左3樣野測試空氣污染的程度..
用了:
1) 雙面膠紙
2 ) 水
3 ) 吸塵紙
過了半個鐘,
雙面膠紙上痴左小量既塵
水裡有一些油污同塵
吸塵紙有小小dirty

點解我地用作測試既野會變成咁呢?
其實係因為食肆經過煮食後,排出大量油煙,令到空氣受到污染,因此用作測試既野都變得 dirty .


我們到了海濱公園附近的河邊進行測試。
首先,擺放了三樣測驗用品:
1 )雙面膠紙
2) 水
3)吸塵紙
經過半個鐘後,發現
三樣物件,只有水有小量的塵,其他都很乾淨。


點解我地用作測試既野會變成咁呢?
是因為在這附近沒有太多車輛,而且又種滿樹木,減少空氣的污染,令空氣比較清新。
我們亦在靠近學校的公路旁放置這三樣測驗工具。
今次我們與其他兩次的測驗不同,我們首先把公路旁欄杆其中一柱抹乾淨,然後待半個鐘後進行測驗。


經過半個鐘,結果水裡有大量沙塵,雙面膠紙也痴滿塵,而我們就用吸塵紙抹一抹抹乾淨過的欄杆柱,結果吸塵紙上有很多塵積,十分 dirty。

Food.
I am the food act to discharge under the greasy dirt to place the left 3 type of wild test air pollution the degree.
Has used:
1) the two-sided gummed paper 2) the water 3) vacuummed the paper half clock, on the two-sided gummed paper in the crazy left small amount already dust water had some greasy dirt to vacuum the paper with the dust to have small dirty

The spot will solve me to serve as the test already wildly to turn 咁?
Is actually because boils the food after the food process, discharges the massive lampblacks, causes the air to be polluted, therefore serves as the test wildly already becomes dirty.


Have carried on the test we to the seashore park nearby riverside.
First, has placed three type of examination things:
after 1) the two-sided gummed paper 2) the water 3) vacuums the paper passes through half clock, discovers three types of things, only then the water has the small amount dust, other are very clean.


The spot will solve me to serve as the test already wildly to turn 咁?
Is because nearby this not too many vehicles, moreover plants the full trees, reduces the air the pollution, makes the air to be quite fresh.
We also in approach the school nearby the road to lay aside these three type of examination tool.
This we are different with other two time examination, we first a parapet column wipe the road nearby cleanly, after then treats half clock, carries on the examination.


After half clock, in the water has the massive sand dust finally, two-sided gummed paper also crazy full dust, but we use to vacuum the paper to wipe the clean baluster column, finally vacuums on the paper to have very many dust products, very dirty.
