Si S Waste Heat And Distributed Energy White 2007
This document discusses waste heat and distributed energy generation. It notes that large centralized power plants currently supply most customers, but distributed generation near points of use could avoid about 50% of energy bills. New distributed generators range from 0.5-5MW in size. Waste heat is a necessary revenue stream as gas is expensive. Research into waste heat includes nanoscale materials, catalysts, thermal design, heat transport and conversion applications like cooling, desalination and industrial processes. An example trigeneration project at Hornsby City Library uses a microturbine and desiccant cooling to reduce CO2 emissions. Organic Rankine cycles and thermoelectric power generation are also discussed as future opportunities.

3020 prejudice simulation
The document summarizes a classroom simulation activity where students were assigned to either a "blue-eyed" or "brown-eyed" group to demonstrate the effects of discrimination. The blue-eyed group had privileges while the brown-eyed group faced restrictions. Reflections found the privileged group felt overtreated while the unprivileged group felt anger and like being "bossed around." The class's action plan was to share the activity with other classes to promote understanding of prejudice.
All powerpoints together
The document discusses stray dogs in Moscow. It provides background on what stray dogs are and why there are so many in Moscow. There are approximately 35,000 stray dogs in Moscow. They pose problems like transmitting diseases and biting people. Solutions discussed include building shelters, catching and sterilizing dogs, but it is difficult to completely remove dogs from the streets. The group visited a shelter called BIM that had better conditions than some government shelters. Their action plan was to write a fictional diary from the perspective of a stray dog to raise awareness.
5tj environment
The document discusses different types of pollution including air, water, and land pollution. It notes that air pollution is caused by burning fossil fuels which releases gases that contribute to issues like global warming and health problems. Water pollution can result from oil spills, dumping of waste, and farm runoff, harming wildlife and causing health issues. Land pollution from garbage and construction waste destroys wildlife habitats and affects the environment. The document encourages reducing pollution through actions like using public transportation, recycling, and not smoking to help address these issues.
Poaching exhibition
Poaching of elephants and rhinos occurs for their tusks and horns, which are used for ivory and traditional medicine. Poachers often use weapons and sell the animal parts for drugs, weapons, or quick money. Captured poachers may be fined or dealt with by the military. Poaching happens in areas like East Africa, India, and South America and threatens animal populations. Groups like WWF, IFAW, and others work to stop poaching through rangers, petitions, awareness, and funds to protect threatened wildlife.
Drugs and peer pressure
This document discusses various drugs and how peer pressure can influence drug use, especially among teenagers. It describes how peer pressure works by influencing people to do things to fit in with their crowd. Several drugs are mentioned, including heroin, marijuana, and cocaine. Heroin is described as the most harmful drug that can cause serious health issues. Marijuana is said to impair memory and motor control. The document advises that teenagers take drugs to fit in and those most vulnerable have low self-esteem or lack a supportive family structure.

The affects of technology on the environment
The document discusses renewable energy sources and recycling as positives that can help address industrial waste management and pollution issues. It also notes some negatives related to technology, such as industrial, electronic, nuclear, radioactive, and chemical waste. The document encourages small actions like recycling, biking/walking, and using energy efficient search engines to cumulatively make a big difference and help address environmental challenges.
Industrial farming room 3026
The document discusses the cruel conditions animals face on industrial farms versus ethical farms. On industrial farms, pigs are confined to small crates where they cannot turn around, piglets are separated from mothers at 2 weeks, and pigs often have their tails docked. Chickens are the most abused farm animal, overfed to an unhealthy size, confined to small wire cages causing injury, and having their beaks trimmed or removed. Cows are confined to small cages and sometimes have their tails removed, and some are shot in the head with electricity before slaughter which paralyzes but does not kill them. In contrast, on ethical farms animals have more space and humane treatment, such as pigs and chickens having room to move freely and cows
3020 prejudice simulation1
The document describes a classroom simulation where students were divided into privileged and unprivileged groups based on eye color to demonstrate social dynamics and prejudice. The unprivileged brown-eyed group felt angry and controlled, while the privileged blue-eyed group felt overtreated and embarrassed. After reflecting, students created an action plan to repeat the simulation for younger students and spread an anti-prejudice message.
3015 water pollution
Water pollution is caused by factories, people, and chemicals from home cleaners. Natural home cleaners are a better option as they don't pollute the water or environment with chemicals and they are inexpensive. Many things can pollute water like oil, trash, liquids, soap, waste, drugs, pills, dirt, and toxic waste. People who use polluted water often feel unwell because they have no money, homes, or access to clean water. Some pollute due to laziness, lack of care, or lack education about pollution. We should recycle, limit water waste, properly dispose of garbage, avoid polluting drains, inform others, and teach people in order to take responsibility for not polluting our
3013 water usage
The document appears to be a quiz about water usage and conservation. It contains multiple choice questions about topics like how much water different household appliances and activities use, where water comes from and goes after use, and statistics about average water usage. The questions cover both domestic water use and broader topics like farming, industry and the water cycle.
3014 tech add
The group presents information on electronic addictions. They show bar graphs of average time spent on electronics by 3rd, 4th and 5th graders. Electronic addictions can cause issues like violence, failing grades, and health problems. Examples are given of people who dropped out of school or neglected responsibilities to play games. The group plans to write an article for a newsletter to convince parents to set time limits to address this issue. They answer questions about addiction symptoms and effects.
