Module 6 : Weather And Climate Changes

The release or agitation of the water would release the co2 causing the water to rise and evaporate.

* Students have been studying the water cycle as a part of a unit about the Earth’s water. These following activities are for independent practices for students to show their understanding of the water cycle. These activities are to be used after instruction has been taught and is used for independent practice.

Information from the Canadian Government website explains some factual information about what climate change is and how it is affecting Canada. From the website, it highlights some key information and basically explains what climate change is. It explains the causes and impacts of climate change and possible solutions to help the environment.

The hypothesis was, if you decrease the atmospheric pressure inside the bottle, then it will form a more sizable cloud, because the pressure inside the parcel will be slightly higher than the outside pressure and when the pressure is quickly released, the molecules will condense the liquid and cool it. The hypothesis was supported in this experiment because the lower pressurized bottle, the independent variable, filled more rectangles or cubelets than the high pressurized one. The group with the lower pressure had an average of filling 87.3 rectangles or cubelets with the highest being 89 and the lowest being 86. However, the group with the higher pressure had an average of 83 rectangles or cubelets with the highest being 85 and the lowest being 81. The theory behind these results were that water vapor gets into air mainly by evaporation. Some of the liquid water from the ocean, lakes, and rivers turns into water vapor and travels in the air. Some clouds form as air warms up near the surface and rises. Eventually, enough moisture will condense out of the air to form a cloud. “That warmed air starts to rise because, when warm, it is lighter and less dense in the air around it. It is easier for water vapor to condense into water droplets when it has a particle to condense upon. Eventually, enough water vapor condenses upon pieces of dust, pollen or other condensation nuclei to form a cloud.” The vapor becomes small water droplets or ice crystals and a cloud forms. (UCAR) This information could be applied to other fields of studies such as nephology, which is the study of clouds, and air pollution. Prior to the industrial revolution, it is believed that there were fewer clouds but it is still unclear how much an increase in clouds may affect the earth’s temperature. Clouds both reflect rays from the sun for a cooling effect and trap heat to create a

Have you ever wondered what is left after something evaporates? Evaporation is a very interesting topic, that is one of the reasons I chose this. I have learned so much facts about evaporation while researching it. Some things I never thought I would learn. Using the information in this report can help you understand about the history and facts about evaporation. I think that learning more about evaporation may help to explain why liquids don 't evaporate at the same rate.

2. How do we know climate in the past has changed, and what those changes were?

The final step in the water cycle is precipitation. Precipitation is when water is released from clouds in the form of rain, acid rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the earth. The most common type of precipitation is rain.

This experiment is designed to facilitate an understanding of the principles involved when water flows through a pervious material such as soil.

This paper is on our seventh grade science project about which liquid evaporate the quickest. We are researching and testing which liquids evaporate the fastest. Liquids are used to keep you hydrated, and can cause different climate in different areas. It depends on if you live close or if you’re far away from large bodies of water.. Precipitation and evaporation, are the two main parts of the project and it is what this project is based off of because when liquids evaporate from the ocean and the particles rise and are caught into the clouds and are saved until heavy enough to fall and turn into rain, sleet, snow, or hail which is decided on temperature.

Climate Change is a big mystery for Today’s Scientists, There are ways scientists can predict what the climate will be like in the future or how it will change. There are only so many ways to predict the climate change.

It's been interesting to see the warm weather. In the first week of November, it's nice to see people being happy with the warm weather. It’s still strange to see the warm spell in a month that’s supposed to be very cold. In Washington D.C, the city is running 5.4 degrees cooler than normal. Since 1872, Washington D.C has recordings of warm temperatures for November and though 70 degree weather is less common during the days passing, it averaged 3.6 of them over the month. This ends a 30 year span. According to the Washington Post, there are changes in the recorded history of warm temperatures in the month. The highest record high was November 6 in 1948. Record warm low was 65 degrees in 1938. Record highs are more threatening than the record lows.

The hypothesis that water would evaporate the fastest was incorrect. When studying research hydrogen bonding in water makes them bond together thus making it slower to evaporate. The experiment explained that the liquids that didn't have as much hydrogen bonding evaporated faster. To improve this experiment one could test different liquids and put them in different locations. An additional experiment that could be tested would be if temperature affects evaporation rates.

Stephen is a ten year old boy who hears about the term “climate change” and doesn’t know what it is or the issue towards it. Stephen decides to go out on an adventure and discover himself what is climate change. Stephen’s first stop is in Antarctica where he meets a polar bear named, Cora that is sad because his playground, known as the glaciers are melting. Glaciers are large sheets of snow and ice that are found on land all year long. Warmer temperatures cause the glaciers to melt faster than they accumulate new snow. Cora explains to Stephen why the glaciers are melting, and then teaches him about the difference between weather and climate change.

The IPCC 5th report on climate change dictates we may have hit the no-return mark before action of climate change becomes too late, with a high degree of agreement, it is clear that we live in a carbon-constrained world with a carbon budget beyond which the irreversible catastrophic impacts of global warming may not be avoidable. To have a 50% chance of staying below 20C of global warming, 62% of fossil fuels proven reserves, and 88% of coal reserves must stay in the ground. Huge new fossil fuel developments, like the Galilee Basin in Australia, the tar sands in Canada and new resources in the Arctic, cannot be developed.

“Natural disasters have killed more than 600,000 people and left behind trillions of dollars in damages in the last two decades, the United Nations said Monday.” (Chan) Extreme weather has caused millions of casualties and extreme damages over the years, but lately there has been an increase in severe weather events. This is causing problems in the US, with the amount of tornadoes rising in tornado alley “Tennessee experienced a 67 percent increase in tornado activity in 1983-2013 compared to the 1954-1983 time period. Oklahoma experienced a nearly 35 percent decrease in tornadoes in 1983-2013 compared to 1954-1983.”
