Garden Science Week 3

This week I had 2 projects. The first project was a self-watering potted plant. The second project is a water garden.

Things you have to consider with your soil is that your soil must contain organic matter to provide minerals for all of your plants.The pH level is very important for your plant’s, a good soil pH level is about 6-6.5.

A couple things to remember when composting is to always keep your compost pile moist during warmer months, and then flip the compost every once in-awhile.

Essay lesson 10: Earth Materials

Earth is made up of rocks and rocks are made from minerals. Those minerals are made up of elements. Some of these minerals have two or more elements but some minerals only have one.

Minerals

 Minerals must naturally occur; it has to be earth made to be a mineral. They are not real if a scientist makes it. Minerals are inorganic which means they are dead. Minerals are crystalline  which means their atoms are formed together to make a 3D form. Minerals are solid which means they stay stable at room temperature. Many minerals have only two elements like salt .

Mining 

Mining  can be very dangerous like in 2010  lots of people got stuck in a mine but they all got out safely . There are three different mining methods: the first is underground mining.underground mining when they mine precious metals like gold ,silver and platinum. underground mining is very expensive so they have to get great value. Surface mining is the second major type of mining; it is less expensive and often base metals and minerals can be extracted from the surface. The third is placer mining often metals can be separated from sediment in rivers  or streams .There is a tool called the slooce trap that saves valuable  material and separates it from sediment .

Week 3 of Architecture

This week I learned about landscape design. A few principles in designing your landscape are balance, rhythm, and emphasis. Emphasis adds force and intensity. To stop repetition and make your landscape interesting add at regular intervals.balance can make your landscape formal or informal you can have a symmetrical or an asymmetrical. If you have a very large yard with tiny, sparely placed plants, then the yard may be out of proportion. Same as if you have a small yard full of massive plants and trees that are overgrown, then the yard may be out of proportion. 

Week 2 of Architecture

This week we talked about landscape architecture. There are 3 principles of great architecture, durability, utility and aesthetic quality. Before 1850 most of the landscape was palaces, monasteries and government buildings. Then in 1850-1950 most landscape projects were cemeteries, parks, and suburbs. And from 1950-now most landscapes are malls, office buildings and suburbs. Landscape developers improve the outdoors by adding curbs and protecting the soil. Land development is like parks, retail centers and resorts. 

Week 6 of weather

This is my last week of weather and I will be starting landscape architecture.This week I learned about how meteorologists forecast weather.

 Meteorologists use many tools to help them forecast weather such as a barometer. A barometer measures air pressure using mercury. There are 3 types of barometer a liquid barometer, a mercury barometer and an aneroid barometer. The higher the pressure the better the weather but when the  pressure is low that’s when there are more clouds, rain, thunderstorms, and even tornados and hurricanes. Another type of meteorologist tool is an anemometer. An anemometer is a tool that measures wind speed. There are a few types of anemometers but the most efficient one is the 3 cupped anemometer. An anemometer uses rounded bowls at a 45 degree angle to catch the wind. Another type of tool they use is a rain gauge. A rain gauge is a tool that meteorologists use to measure how many inches of rain we will get

Week 5 of weather

This week we talked about hazardous weather. There are 40,000 thunderstorms a day world wide. The life cycle of a thunderstorm has 3 parts . The first is the towering cumulus stage then the maturing stage then the dissipating stage.

A tornado consists of moist air and is visible because of these water droplets. Some tornadoes last from a few seconds to minutes but most stop within 10 minutes. A tornado will gradually lose intensity. Most small tornados do a lot of damage while most big tornados will do very light damage.

Hurricanes can only develop were the sea temperature is 26 degrees and big hurricanes develop in 28 degrees. Hurricanes need wave patterns or thunderstorms to develop. Hurricanes can only develop between 8 and 20 degrees north of the equator

Week 4 of weather

This week we talked about cloud formations. Clouds provide precipitation for plants and keeps us warm by holding in the heat. Condensing water vapor forms clouds. Clouds make up is partially water but there is dirt in the air that these particles form around. Cool air cannot contain as much water vapor as warm air. Some clouds change stages. A few cloud stages  are:

the stages of clouds
  • The towering cumulus stage
  • The maturing stage 
  • The dissipating stage

Week 3 of weather

This week We talked about polar jets and subtropical Jets. Polar Jets are more powerful but are lower in the air they are only 23-39,000 feet above ground. Subtropical Jets have less power but are higher in the air then polar Jets ,they fly between 33-52,000 feet in the air. The air that is in jet streams can travel over 200 miles per hour. They are used  to forecast weather.There are several main types of climate. A few of them are the tropical climate which is above 64 degrees all year round. Another is the dry climate, this climate is from 68 to 90 degrees all year long. 

Week 2 of Weather

 This week we talked about wind. When air is moving vertically, it’s called an updraft. Air motion is caused by 3 forces. The first force is the pressure Granite Force also known as PGF. This is when high pressure areas force the air into low pressure areas. The second force is the Coriolis Force this is when the rotation of the Earth causes air to turn. In the Northern hemisphere hurricanes spin in one direction and in the southern hemisphere they spin in the opposite direction. And last but not least the third force is friction which slows the flow of wind. 

Weather week 1

This week we talked about the atmosphere. There are a few layers of the atmosphere and they are classified by the temperature. The lowest layer is the troposphere which is 10 miles high at the equator and 4 miles high at the poles. As temperature decreases the altitude increases. The second layer is the stratosphere. This layer begins 6-8 miles above sea level and ends 31-34 miles above sea level. Unlike the troposphere in the stratosphere as the temperature increases the altitude increases. Jet powered airplanes can fly here but not propeller powered. The third layer is the mesosphere. This layer starts 31 miles above sea level and ends 50-53 miles above sea level. The average temperature is -120 degrees .This level is too high for jet powered airplanes and is too low for satellites. The fourth layer is the thermosphere. This layer starts 50 miles above sea level and ends 312-620 miles above sea level.
