Weather

Before this activity i thought the weather would be getting warmer and warmer. The weather unit showed how the temp. varies depending on different days and how the cloud coverage is on different days, due to the temp and precipitation. The weather did not keep going up it varied . This unit has to do with my topic by it showing the weather and how it changes, the greenhouse effect has to do with the weather and how its changing, this project showed that the weather changes and what the cloud coverage would be. I learned that you cant always be sure of what the weather will be like there's no grantee. I also learned how much weather can vary temp. wise.

wes D

Before this activity i didnt know much about global winds but this activity shows us that depending on which way the earth rotates the objects on the earth will move different ways. We took an index card and cut it in two different directions and twisted them opposite ways and that showed the line in which objects would move on the earths surface, indicating how water currents, and wind currents would move. This activity taught me to understand the way the winds will move depending on the way the earth moves. I know now that if the earth is turning clockwise then the wind will move counterclockwise and vise versa.

This activity doesbt really rlate to my topic because my topic is greenhouse effect and that has to do with the warming of the earth and this has to do with the global winds and what direction they move.

Greenhouse Effect

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms the earths surface. This effects us by it causing weather changes and environmental problems. This causes many issues within the science world and even in our world. The gases are eating away at the atmosphere causing the sun rays to come in and warm things that are not meant to be warm, thus causing global warming.

activity 4.

This activity has to do with my subject by it having to do with the greenhouse effect. The activity delt with the warming of the earth and how different things cause it to warm up differently. Like with the clouds, it caused the material to get warmer slower, and the bottles with no clouds got warmer faster. This activity showed how the gases got trapped causing fog in the bottle, and how different materials with different conditions heated up.

Why is nature playing april fools?

Nature is playing April fools by it is making us think that it is going to be warm but there is a cold front coming in and its going to snow. Its kind of fooling us with making us think its going to be warm when really by the end of the day its going to be cold and snowy. The cold is coming in because of the cold front from the northwest winds. The La Nina conditions have a part in this by it having cold ocean temps. that come in to the coast causing snow and other cold conditions. the ploar circulation circulates the air. The North Amerian Jet Stream causes the cold weather by bringing in the cold with the jet stream. The stream is strong causing it to pull in cold weather.

activity 2.

In this activity we learned about how and why we get percipitation. We made predictions on what we thought then we did an activity that showed us what was true about it. This activity has to do with my subject the greenhouse effect because the greenhouse effect causes precipitaion and this activity showed how it is caused.
