Wire mesh screen
Wire mesh screens made from high carbon spring steel wire are proposed as an alternative to mild steel plate screens for vibrators and hot mix plants. The steel wire screens have several advantages: [1] They allow more production as square openings provide a larger opening area than round openings. [2] The diagonal length of square openings requires the openings to be around 10% smaller. [3] The steel wire is stronger than mild steel plates and will last much longer. [4] Multiple layers of wire reinforce each other, increasing strength further. The wire mesh screens are also more economical despite their longer life. Specifications and pricing for various wire mesh screen options are provided.

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. Limitations around sample size and measurement accuracy are discussed.
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.

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.
The finite times
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.
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.
The finite times
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.
The finite times
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. Alternative energy sources like solar and wind could help manage this non-renewable resource more sustainably.

Ancient China was an important early civilization that made many important inventions. Life was difficult for children, especially poor children who had to work long hours to help their families. Some key inventions and developments of Ancient China included the compass, gunpowder, writing system, and printing. Farming was a major part of everyday life, with crops grown along rivers in central China and by peasants for wealthy landowners in southern China. Studying Ancient China provides insight into their legacies and how life was different than in ancient Korea.

The document summarizes an experiment to investigate the relationship between total finger length and arm length in 15 Grade 4 students. Measurements of each finger and the arm were recorded and it was found that 14 out of 15 students had arm lengths greater than their total finger lengths, supporting the hypothesis. On average, arm lengths were 13.18cm greater. The conclusion is that for 9-10 year olds, arm length is typically greater than total finger length. Limitations around sample size and measurement accuracy are discussed.
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.

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

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.
Ancient Rome
Ancient Rome lasted from 753 BC to 476 AD and was located along the Mediterranean Sea. Roman society was divided into classes like patricians, equites, and plebeians. Patricians were the richest and owned land and slaves, while plebeians did various jobs and trades. Romans worshipped many gods adapted from Greek mythology and built temples to honor them. They also left architectural legacies like aqueducts, roads, and structures like the Colosseum that are still standing today. Roman influence can also be seen in modern European languages that derived from Latin.
Ancient china
Ancient China was an important early civilization that made many inventions and contributions. The civilization developed agriculture, with farmers growing crops like rice and vegetables. Food availability varied between social classes, as rich people had easier access to food than poor farmers, who were important to the emperor but had to work hard to grow different crops depending on the climate in different parts of China.
Ancient civilization of egypt
Ancient Egypt existed along the Nile River from 2800 BC to 1300 AD. The Egyptians made many discoveries and innovations, including a 365 day calendar, hieroglyphic writing, ships and sailing, irrigation techniques like the shaduf, and grand architecture like pyramids and the Sphinx. They also developed an intricate belief system involving gods like Osiris and Isis and the important role of the pharaoh. Trade was important between Egypt and other civilizations, and agriculture near the Nile provided a foundation for food like wheat, barley and grapes.
Measure
The study investigated the relationship between total finger length and arm length in 15 students aged 9-10 years old. It was hypothesized that arm length would be longer than total finger length. Students' individual finger lengths were measured and totaled, then their arm length was measured. On average, students' arm lengths were 149 mm longer than their total finger lengths, supporting the hypothesis. However, the small sample size from only one age group and location limits the reliability of the results. More standardized measurement techniques could also improve the study.

1) The student learned that finite resources like fossil fuels are limited and will run out, and that using alternatives like solar and wind is important.
2) A home energy audit found 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 boxes, talking to classes, and collecting paper to send to a recycling center.
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.

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

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.

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.

Measurement investigation
- 1. Measurement Investigation: What is the relationship between total finger length and arm length? Aim: To investigate the relationship between a person’s total finger length and arm length. Hypothesis: We predict that Grade 4 student’s arm length will be longer than total finger length. Materials: 1 measuring tape 1 pencil 1 sheet of paper 1 clipboard 13 Gr.4 students Method: 1: Collect your materials. 2: Draw a table with 9 columns (name, 1st finger, 2nd finger, 3rd finger, 4th finger, 5th finger, arm length & difference). 3: Ask someone to stretch his or her fingers. 4: Put the measuring tape at the end of the person’s fingers. 5: Record the length in millimeters. (Optional) 6: Work out the total finger length. 7: Measure the length of an arm (Do not record the arm span!). 8: Record the length of an arm. 9: Subtract the total finger length from an arm length. 10: Record these measurements in the right headings. 11: Repeat the same steps with the other Gr. 4 students. 12: Observe how much difference there is between the total finger length and an arm length.

On average, people’s arm length was approximately 42cm longer than their total finger length. Conclusion: Our hypothesis was correct. We conclude that Grade 4 student’s arm lengths were longer than total finger length. Discussion: Our result can be un-reliable. We only measured 15 students and they are only 9~10 year olds that we measured. We had some difficulties getting accurate measurements. Some people didn’t measure the same way and some didn’t always started on 0cm. Some stretched their fingers, which could add up to 1mm. We also found
