What is global warming?
World-wide increases in temperature caused by increase of greenhouse gasses such as CO2 from burning fossil fuels.
100
What is the pH of acid rain?
5.6 or lower
100
What are 3 ways we can prevent water pollution?
Recycle, dispose of waste properly, don't litter, don't dump chemicals down the drain
100
What is the solid portion of sewage called?
Sludge
100
An experiment was designed to test which type of rock is most resistant to acid rain. What is the independent variable?
Type of Rock
200
How can you minimize your exposure to air pollution?
Spend less time time outdoors in cities. Wear a mask when exposed to heavy pollution.
200
What causes acid rain?
pollution combined with the moisture in the air
200
What are the three main categories of water pollution?
Sewage, Industrial, Agricultural
200
When we flush, where does it go?
flush-->sewer-->sewage treatment plant-->rivers/lakes/farms/recycling
200
An experiment is designed to determine what type of rock is most resistant to acid rain. What is the dependent variable
damage to rock/weight of rock
300
Which body system is most likely to be affected by air pollution?
Respiratory System
300
What can be effected by acid rain?
rocks, animals, plants, people, building materials
300
This type of water pollution is caused by dirt and sand being washed into the water from construction sites and farms.
Sediment Pollution
300
Where is "sludge" often used?
Farms as fertilizer
300
What are 3 factors held constant in the acid rain lab?
amount of vinegar, type of cup, time, weight of rock, temperature, person weighing, scale
400
This type of air pollution is more common in cities. It occurs naturally high up in the sky where it is beneficial, but when it is close to the ground it is harmful.
ozone
400
Where in the US is acid rain most common?
Northeast
400
What is the difference between point source pollution and non-point source pollution?
Point source- a specific thing that you can see causing pollution ex. pipe of sewage, nonpoint- over a larger area, but cannot see directly ex. agricultural runoff
400
Where does the water go from the sewage drains in streets?
Straight to rivers/lakes/ocean. It is NOT treated in a sewage treatment plant!
400
After being exposed to vinegar, the following results were recorded of total weight loss. Sandstone lost 3g, limestone lost 6 g and pea stone lost 1 g. What conclusions can you make?
Pea stone is most resistant to damage by acid rain. Limestone was damaged the most.
500
This air pollutant can cause extreme drowsiness and confusion
Carbon Monoxide
500
What two gasses cause acid rain?
nitric acid and sulfuric acid
500
What is it called when there is an overgrowth of algae in a body of water, caused by nitrogen and phosphorus runoff?
Eutrophication
500
What should you do with waste oil, medicine, or chemicals.
Dispose of it PROPERLY! (bring it back to the store you can buy it from, they usually have appropriate disposal methods)

How is the acid rain lab relevant to us in the real world? (how does it apply to us?)
Acid rain is a real problem here in CT, so building materials need to be considered when constructing things that will be outside.
