Tutorial Schedule today (test study session in S-020 until 4pm)
Your 3 Air Pollution drawings are due today for 30 points
Homework stamp for 37. Bozeman Solid Waste video notes
Notes:
-I had zero people show up for the first APES test study session on 4/18...? Please check blog post for resources.
-I had one person come to tutorial to retake a test.
Here is the grade breakdown for my APES classes:
8/60 (13%) have an F (failing)
5/60 (8%) have a D
3/60 (5%) have a C

Continuing Earth Week...
-Read your earth week pledges (did you forget to add one?)
-Today is Water Wednesday
Water Facts of Life
Ride the Water Cycle With These Fun Facts
- There is the same amount of water on Earth as there was when the Earth was formed. The water from your faucet could contain molecules that dinosaurs drank.
- Water is composed of two elements, Hydrogen and Oxygen. 2 Hydrogen + 1 Oxygen = H2O.
- Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.
- Water regulates the Earth’s temperature. It also regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes.
- 75% of the human brain is water and 75% of a living tree is water.
- A person can live about a month without food, but only about a week without water.
- Water is part of a deeply interconnected system. What we pour on the ground ends up in our water, and what we spew into the sky ends up in our water.
- The average total home water use for each person in the U.S. is about 50 gallons a day.
- The average cost for water supplied to a home in the U.S. is about $2.00 for 1,000 gallons, which equals about 5 gallons for a penny.
- Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water.
Interesting Info from PPS regarding sustainability:
Happy Earth Day!
Portland Public Schools has a growing sustainability program that incorporates the dual approach of promoting student ecoliteracy while reducing the District's environmental footprint. We aim tospark student's curiosity and empower them with capabilities to create a more sustainable future by encouraging students topositively respond to our ever-changing world.

Today’s Sustainability Topic: Energy!
PPS is dedicated to reducing our energy consumption, increasing our efficiency, and investing in renewable sources.
· Energy Conservation: the prevention of wasteful energy usage, usually through human behavior change and/or automated building controls.
· Energy Efficiency: reducing energy consumption by using building systems, equipment and appliances that use less energy to attain the same output.
· Renewable Energy: use of clean, non-fossil fuel energy sources that are constantly replenished by natural processes, such as solar, wind, and hydroelectricity. Solar energy projects can be found at 18 schools through the Solar Roof Project, Solar 4R Schools, and other grant funded programs. PPS has one wind power project at Skyline Elementary School.

Power Patrol
· The Power Patrol is a student-run energy-monitoring program in which students monitor energy use in their. This is an activity that students can do at any point during the year. To learn more about the Power Patrol program,

Energy Audit
· One of the best ways to relate energy conservation to the real world is to have students complete an energy audit of their school. Students collect data and do basic calculations to estimate total electricity use and cost for the school. To have students conduct their own Energy Audit,

Plug Load Reduction
· One of the biggest burdens on our schools' aging electrical systems are personal appliances such as refrigerators, microwaves, space heaters, and coffee makers.
· Students can do a survey of their school to identify personal appliances and leave notes with the calculated amount of energy they are using.
Partnership Spotlight: Better Buildings
PPS is a proud partner of the U.S. Department of Energy's (DOE) Better Buildings Challenge (BBC), committing to reduce our energy use by 20% by the year 2020. During the month of July, PPS was listed in the BBC's top 10 solutions, nationwide, for our implementation model. You can view our implementation model

Our Last Unit of APES!
Unit 8: Global Change (Stratospheric Ozone, Global Warming, Loss of Biodiversity)
In your notebook, do an independent write for 5 mins:
-What do I know about global change?
-What do I want to know about global change?
Then, share with table partners.
Lastly, share out with class and make a list.
greenhouse gases - gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.
global warming - a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
climate change - a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Read over these articles with your table partners, adding to your 'what you know':
Are the ozone hole and global warming related?
Is the ozone hole causing climate change?
