Length investigation
The document describes an investigation that measured the lengths of fingers and arms of 20 people to compare the two. It was hypothesized that arms would be longer than total finger length. The results showed that on average, total finger length was 28.57cm while average arm length was 56.275cm, supporting the hypothesis that arms are longer than fingers by about 28cm on average.
Aim
The document summarizes an experiment to investigate the relationship between total finger length and arm length. The hypothesis was that arm length is longer than finger length. 20 volunteers had their finger lengths and arm lengths measured in centimeters and recorded. The results showed that all 18 peoples' arm lengths were longer than their total finger lengths. The conclusion is that the hypothesis that arm length is longer was correct.

Length investigation
The document describes an investigation into the relationship between total finger length and arm length in people. The hypothesis is that a person's arm length will be greater than their total finger length. 20 people had their individual finger lengths and arm length measured and recorded. The results found that for 9-12 year olds, most had arm lengths greater than their total finger length, with an average difference of 27cm. The conclusion is that the hypothesis that arm length is greater was supported, but it was noted that a larger sample size would be needed to generalize the findings.
Procedures
The group made a coffee filter parachute with gold stickers and black string to carry a toy firefighter. They dropped the parachute from 3 meters high and timed how long it took to reach the floor, testing different slit sizes from 0 to 6 centimeters. They repeated the drops for each slit size to complete all trials.

Coal forms over millions of years from the remains of dead plants and animals. It is collected through underground or surface mining methods. We depend on coal as an important resource because it provides electricity, heat, and is used in manufacturing industries. However, coal mining and the factories that use coal for energy can pollute the air and water and damage habitats. More sustainable alternatives like solar and wind could help reduce our use of this finite resource.
Measurement investigation
The document describes an experiment to investigate the relationship between height and jumping distance in 15 9-10 year old students. It was hypothesized that height would be greater than jumping distance. Each student's height and maximum jumping distance were measured and recorded. The results showed that in all cases height exceeded jumping distance, on average by 34.4 cm. It was concluded that for 9-10 year olds, height is always greater than jumping distance.

Wildfires can start naturally from dry grass rubbing together or lightning strikes, but are also frequently caused by human activities like campfires or discarded cigarettes. Wildfires spread extremely quickly and can destroy everything in their path, making evacuation critical when they approach. Firefighters have developed strategies to control and extinguish wildfires, such as dropping water or retardant from aircraft or using giant hoses. The best approach is preventing and quickly detecting wildfires so that firefighters can respond before they grow out of control.

Coal is a black solid rock that was formed from dead plants and animals that lived millions of years ago. It is collected through surface mining, using machines to dig holes, or underground mining by building tunnels. Coal is then brought out of the mines and transported to power plants where it is burned to produce electricity. However, coal is a finite resource that takes a long time to form, and our heavy reliance on it for electricity is not sustainable and also harms the environment by polluting the air. Alternative energy sources like wind, solar, and water could help reduce our coal usage.

Ancient egypt
Ancient Egypt existed along the Nile River from 3200 BCE to the beginning of the common era. The Egyptians were the first to develop a form of writing known as hieroglyphics, carved on materials like papyrus and stone. Their society was highly stratified, with the Pharaoh at the top and slaves at the bottom. Farming depended on the predictable flooding of the Nile, allowing crops like wheat and barley to thrive. Some technological legacies of ancient Egypt include ships, lighthouses, and advances in writing.

Wood comes from rainforests where loggers use chainsaws or machines to collect different types of wood. Lumber is wood from cut down trees that is used to build houses and make everyday items like paper, pencils, and furniture. The logging industry provides wood that people rely on but cutting down many trees can damage forests. Better management of this resource and reducing wood use could help address the environmental impacts.
Ancient china
Ancient China lasted over 5,000 years and was one of the longest civilizations. It influenced modern China and the world. Some key aspects included the Great Wall, which stretched over 2,100 miles to defend China. Diet varied by class, with poor people eating grains, vegetables and wild game while wealthy ate meat and special foods. Ancient China invented many technologies still used today like gunpowder, paper, printing, and the compass. Society was highly stratified with emperors and nobles at the top and peasants and servants at the bottom.

Underground mining and surface mining are used to collect coal. For underground mining, deep tunnels are built and miners use elevators to reach the coal deposits. Once collected, the top layers of soil and rock are replaced. Coal is a hard black or brown rock that can be burned as a fuel source. It provides an important source of electricity but the heavy worldwide usage of over 5.3 billion tons per year means the supply will not last forever and burning coal harms the environment by contributing to global warming. Better management of coal resources could include reducing usage through recycling and using cleaner energy sources from plants equipped with pollution control technology.
Finite times(oil)
Oil is a finite resource that is formed from the remains of ancient plants and animals. It is usually found underground in rock formations beneath the sea. Oil is collected through drilling wells deep into the earth and using pumps to bring the oil up. While oil provides many useful products and energy, it is non-renewable and its extraction and use also causes environmental damage like global warming. Scientists are working on improved extraction techniques to get more oil from each well and developing renewable alternatives to reduce dependency on this finite resource.

Coal is collected through surface or underground mining methods. Surface mining uses large machines to remove topsoil and rock layers to access coal deposits underneath. Underground mining involves using elevators to access deep tunnels where miners cut coal. Coal forms over hundreds of millions of years from decaying plant matter and is a non-renewable fossil fuel. Communities depend on the coal industry as it provides around 40% of the world's electricity and is used to produce many goods, but it also harms the environment by releasing pollutants like carbon dioxide, sulfur dioxide, and nitrogen dioxide which contribute to issues like global warming and acid rain. Better management of the coal industry could involve using pollution control devices and reducing transportation and other resource usage to

Overall, the student most enjoyed creating a magazine article for the unit and wants to continue improving their writing.
Finite resources reflection
The document discusses finite resources and conservation efforts. It covers how fossil fuels are finite resources that can run out, so alternative energy sources like solar and wind are important. It also describes a school campaign to install recycling bins and educate students about recycling to reduce waste. The document expresses how reducing paper usage can save energy and resources.
Finite resources reflection
Sarthak learned that finite resources like coal, oil, and wood have limited supplies and producing them causes pollution. It is important to conserve these fossil fuels and use alternative energy sources like solar, wind, and water power. Sarthak discovered through a home energy audit that his house uses a lot of energy, so he set goals to conserve more. At his school, an energy audit found issues like lights left on in empty rooms and some classes lacking recycling bins, so goals were set to address these problems. Sarthak helped lead a school campaign to promote paper recycling by making bins and educating others, though it was difficult explaining their proper use to younger students. He enjoyed making a music video at a green screen to
Finite resources reflection
This document summarizes the key things a student learned during a unit on finite resources:
1) Finite resources like coal, oil, and gas are limited and pollute the environment, so conservation is important. Alternative energy sources include solar, nuclear, and geothermal.
2) A home energy audit found lights were left on unnecessarily, so the student set a goal to turn lights off when rooms are empty.
3) A school recycling campaign was launched by making a bin, teaching proper use, and collecting paper to reduce waste of finite wood resources.
Finite resources reflection
The document discusses finite resources and environmental actions taken by a student. It covers the following key points:
1) Finite resources like fossil fuels are limited and examples include oil, coal, and gas. It is important to conserve these resources and find alternatives like solar and wind due to pollution, habitat destruction, and limited supply.
2) During a home energy audit, the student discovered ways to conserve electricity by switching it off at the wall when not in use.
3) The student led a school recycling campaign by making recycling boxes, talking to classes, collecting paper, and sending it to be recycled. It was difficult but important to explain conservation efforts to other students.

Finite resources reflection
The document summarizes a student's learning about finite resources and their efforts to promote conservation. It discusses how (1) fossil fuels are finite and polluting, so alternative energy sources are important; (2) a home energy audit found opportunities to conserve energy by turning off lights; and (3) the student undertook a school campaign and music video to teach peers about recycling and conserving trees.
Finite resources reflection
The document summarizes a student's learning about finite resources and their environmental actions. It discusses that fossil fuels like oil, coal, and wood are finite resources that will run out and cause pollution. The student learned coal reserves on Earth will only last 200 more years. Through a home energy audit, the student discovered they take long showers and set a goal to take shorter ones. At school, the student led an effort to give every classroom a recycling bin and teach recycling. They made a music video using green screen to promote recycling and reducing paper use, enjoying the creative aspects. The student found explaining the project to younger students challenging but rewarding.
Finite resources reflection
The document discusses finite resources and conservation efforts. It summarizes that finite resources like trees, coal, and oil have a set amount that could run out. The document then discusses taking actions like creating recycling bins for classrooms and making an environmental music video to encourage reducing, reusing, and recycling paper to conserve resources. It reflects that the experience of making the recycling bins and music video was enjoyable and the student learned the importance of conserving finite resources through these projects.
The finite times
Coal is collected through surface or underground mining methods. Surface mining uses large machines to remove topsoil and rock layers to access coal deposits underneath. Underground mining involves using elevators to access deep tunnels where miners cut coal. Coal forms over hundreds of millions of years from decaying plant matter and is a non-renewable fossil fuel. Communities depend on the coal industry as it provides around 40% of the world's electricity and is used to make many other products. However, burning coal also harms the environment by releasing pollutants like carbon dioxide, sulfur dioxide, and nitrogen dioxide that cause issues like global warming, acid rain, and smog. Better management of the coal industry could involve using pollution control devices and transition
The finite times
Wood comes from rainforests where loggers cut down trees using chainsaws or machinery. Lumber is wood from cut trees that is used to build houses, make furniture, and produce paper and pencils. The logging industry can damage forests by clear cutting, which removes all trees and damages animal habitats and the environment. A more sustainable alternative is strip logging, which removes trees in a way that mimics natural forest growth.
The finite times
The document discusses the wood industry and its impacts. It explains that wood comes from rainforests where loggers cut down trees using chainsaws or machines. The wood is then used to build houses, make furniture, and produce paper and pencils. However, logging large numbers of trees can damage rainforests and their ecosystems. Clear cutting whole areas can eliminate food and oxygen sources for animals and cause problems like flooding and global warming by reducing carbon dioxide absorption. A more sustainable alternative is strip logging, which mimics natural forest growth patterns.
Grade4 news
Oil is collected from deep underground using large drills and pumps. It is found in places that were once underwater, where dead plants and animals were buried under layers of mud and sand over millions of years. Once extracted, oil is sent to refineries where it is cleaned and separated into useful parts like gasoline, diesel, and kerosene. However, oil is a finite resource that will eventually run out. It also harms the environment by contributing to issues like global warming, air pollution, and acid rain when burned as fuel. More sustainable energy sources could help reduce our dependence on oil.
