What is the Difference between weather and climate

Weather is short term, climate is long term patterns. The climate can be warming, yet  the weather seems to be colder.

Tools:
Air Pressure: barometer
Temperature: thermometer
Humidity: hygrometer
Cloudiness: radar  
Wind speed:
Wind direction: weather vain
Precipitation: rain gauge
Solid:
Liquid:

Eggsperiemnt (Air Pressure)
-hard boiled eggs, flame in bottle, place egg on lip

Prediction:
The air pressure will lower and a seal will be created and the egg will be sucked in.

What happened:
The flame created a quick increase in temperature, so when the seal was created the air pressure dropped so quickly that the egg was sucked into the bottle.

Sling Psychrometer (Humidity) :
We used a sling psychrometer and spun it around for one minute, inside and outside. We compared the temperatures on the dry bulb with the wet bulb to find the relativity humidity.
The air was more humid outside (69) than inside (36).

Measuring clouds:
water vapor, pressure, condensation nuclei(salt, ash, ect)
Water bottle, water, and match
-when you squeeze=high pressure, no clouds, warmer
-let go=low pressure, clouds, colder

Anometer (wind speed): measured with a weather vane
crossing rulers and put cups on each end-count how many  times it goes around

Precipitation:
Wet-rain gauge
can by made with a ruler and cup
Dry-1mx1m snow board

Life, the Universe, and Everything

Creation Myths
1. The Origin of Japan and her People- a deity commanded the land be created .
2.  Ojibway creation story-An animal dove to the bottom of the river to bring soil up so land could be created.
3. Greek myths, three different words that beings would pass through to create life and worlds.
4. An Irish creation story- Life came from the leg of a larger being
5. The Golden Chain-a chain is dropped and an egg is cracked resulting in Earth being developed.

All these tales start with an answer and all of these involved something supernatural and cannot be measured or proven, which refutes all the basic tenants of science.

The Big Bang Theory is reliable because the event can be measured and started with a question. The movement of the solar system leads one to concluded that all the matter in the universe came from one single point. The matter in the universe can be dated and suggests that the first form of matter was very simple and was created at the same time.

If I had $100!

The value of each element of the solar system would be:
Sun: $99.89, which was $0.89 more than I remembered.
Jupiter: 10.6 cents, which was bigger than I thought
Saturn: 3.2 cents
Neptune: .006
Uranus: .005
Small Rocky Planets:
Mars: .00002 cents
Venus:.00003 cents same distance from sun, but much hotter due to rotation and atmosphere
Earth .00003 cents-less than I thought.
Asteroid belt (between Venus and Jupiter)
Commits-made of ice&gas, tail always points away from the sun

Science Misconceptions

What are the reasons for the seasons?
The Earth has different seasons because it sits at a tilt that causes the sun to be strongest at different locations  at different points in Earth's rotation around the sun. The Earth's angle from the sun changes causing different seasons.
What causes the phases of the moon?
The 8 phases of the moon are caused by the relationship between the moon and the sun. The moon tells us time and lets us predict what phase of the moon we will see at what time.

What is Science?

Science is a study of the world around us. Science seeks to answer questions. That is, perhaps, what makes science so complex. Science is a discipline unlike another, due to the fact that so much can fall under the title of science. From biology to geology, there is so much to address when teaching science. Unlike reading or math, science is constantly evolving and a requires the teacher to understand a broad range of topics. One can spend their whole life studying the complexities of one part of the brain, yet teachers must find a way to simplify the material and explain it in a way that allows young children to understand and connect with the material. Many people have a fear of science classes, yet science is one of the most exciting classes to teach and participate in. In a sense, science is everything and therefor anything can be made into a hands-on learning experience. I believe it is the hands-on experiences, that are vital when teaching science, that inspire students to investigate the world around them and see that science is fun.
