- Set up weather instruments in groups of 4 (take measurements for a week)
- Make first observation to post on blog
- relative air pressure – for the first day, note the weather and real pressure
- air temperature
- wind direction
- wind speed
- dew point
- Cloud type
- Cloud cover
- Present data above as found on a weather station map – take a photo to post
- Description of today’s weather and prediction of tomorrow’s weather (colder, warmer, precipitation, clouds, wind)
- Use https://www.weather.gc.ca/analysis/index_e.html to see complete charts for prediction – Provide screen shots of fronts and explain prediction
- Explain whether or not the hydrologic cycle is a open or closed cascading system.
- Use the list of storehouses on page 197 and explain what would happen if each of them experienced increased solar radiation.
- Would the increased solar radiation have an overall positive or negative effect on the earth?
- How would your answer above be different if insolation did not change but atmospheric temperatures increased (Global Warming)?
- Of the different storehouses, which one poses the largest possible risk to people if it depleted? Explain why.
- How does human development (buildings, roads, farms, cities) affect the hydrologic cycle?
- What conditions are needed for clouds to form?
- Why is it safer to drink lake water than ocean water?
- What would you look for in the sky to see if a warm front is coming?
- What kinds of clouds are most common in the Lower Mainland? Explain why.
- Use your knowledge of wind and precipitation to explain why the Pacific Northwest “rains all year long”. Explain what happens in the summer and winter.
Due Fri, May 24.
Complete handout given in class.
- Why is the earth’s energy system considered an open cascading system?
- How would different types of air pollution interact with shortwave radiation and longwave radiation?
- To stay cool in summer, is it better to wear shorts and a tank top on a sunny day or be all covered up? Explain.
- Why doesn’t snow always melt faster on a sunny day?
- How can your chances of getting sunburnt increase from going skiing?
- Why is a clear night colder than a cloudy night?
- Why do football players put black grease under their eyes?
- What would happen to the temperature if a volcanic eruption of ash occurred? Explain with reference to radiant heating.
- If the poles get constant daylight in their respective summers, explain why it is still colder.
- Has human development/activity in your city increased or decreased the temperature around it? Give examples and explain how the actions affect temperature.
- What gases make up the atmosphere and what are their proportions?
- What importance do these gases play in sustaining the biosphere?
- What happens to temperature and air pressure as you move away from the earth?
- If large commercial planes have a cruising altitude of about 10,000m, where are they in the earth’s atmosphere?
- Why is this chosen as cruising altitude?
- Why can’t you open windows on a plane?
- Why is it that no plane has every flown higher than the SR-71 at 25,929m?
- Why does it get warmer again in the stratosphere?
- Generally, what is used to define each atmospheric layer?
- Why does the thermosphere increase in temperature?
- Why can you only see the aurora borealis at the poles?
- What will happen to your helium balloon if you let it go?
Key Question: How can BC’s waste management system be made more sustainable?
- Research how some other countries manage their waste.
How sustainable is the mining industry? What should the future look like?
