Sadler et. al, Wikipedia's misconceptions page ( http://en.wikipedia.org/wiki/Common_misconceptions#Astronomy ), and many educators have cited the power per area argument for the seasons, due to the tilt of Earth in its orbit. Few discussions of the orbital causes of the seasons list length of day, and none I've seen help students see the seasons as a cumulative effect rather than an instantaneous one, thus explaining why January, when the sun is higher in the US, is usually colder than December, or early August is usually hotter than mid-June.

===Siting a wind turbine===
 +
;Course:9-12th grade earth science
 +
;Topic:Atmosphere and land.
 +
;Instructor:Shawn Reeves, physics and earth science teacher
 +
;Audience:9-12th grade students
 +
;Pre-context:This is the first class of the second term of an earth science class. During the previous term, students studied the radiation budget between sun-earth and earth-space. As part of that unit, students learned about solar power, renewables, solar cooking, climate change. They have never seen a histogram.
 +
;Post-context:We show students power curves for wind turbines. Students are asked to revise their inferences based on these power curves, which show that wind turbines have cut-in and cut-out speeds, and make about ten times as much power at 15m/s, a rare wind speed, than at 5m/s, a very common wind speed.
 +
;Activity:Given an anemometer and a wind vane, students explore a virtual world where wind is modeled. With the help of a data-facilitator, students ask questions of the data. Students then analyze the data on their own, then make inferences and reason why those inferences would be important to deciding where to site a wind turbine. Students are directed towards other sources for wind data, such as NOAA ASOS.

#Announce expectations, 1 minute.

##Each student will spend entire class building a mind map of concepts and connections discussed in class, either on paper or using CMap. Making links to existing structure is encouraged.

##Students will discuss ideas with each other, but every student is responsible for their own mind map.
 +
##Students will be expected to raise questions about the data and what it means for siting a wind turbine advantageously for producing electricity. Some relevant considerations are planned for another class; if a student raises such a consideration, the instructor may ask the student to record the inquiry for the next class meeting.

#Class is given a data set and asked to generate questions to ask of the data. 10 minutes

 +
;Driving question:How can we characterize wind so that we can predict wind power generation?
 +
;Concepts:wind speed, wind direction, compass, wind rose, histogram, statistics, prediction.
 +
;Goals:Students will present wind data that will help anyone understand whether a site will produce sufficient wind power.
 +
;Objectives:Students will create charts and or tables that clarify pertinent data. Students will organize data into sets that aren't too large to handle, nor too small to be meaningful.
 +
;Discussion:One of the more experimental methods of this lesson is the use of the "data-facilitator." The data-facilitator can be a student or instructor or aide who knows how to take an analytical question and turn it into a structured query, using the structured query language to most database programs. The instructor is going to need to measure the knowledge and skills the students bring to the course, specifically about histograms, statistics, the relationship between statistics and predictability, and the concept of speed.

Explanation

These plans are designed for trial in EDUC 6470, and may be developed for my future use.

For any of these lessons, I would like to focus on the tension between free inquiry and predetermined goals, as in Furtak 2006.

Optional concepts indicate the possibile learning outcomes depending on student or teacher choice of paths during the lesson.

Planning Group

A group of four in our class is collaborating on our plans: Joseph Ashong, Jeff King, Shawn Reeves, and Adi Md Sikin.

Joseph works in nutrition, Jeff in math, Adi in food processing, and I in high school physics.

Meetings

2010-03-03
We discussed our subjects, possible goals and concepts for our students.

This is the first class of the second term of an earth science class. During the previous term, students studied the radiation budget between sun-earth and earth-space. As part of that unit, students learned about solar power, renewables, solar cooking, climate change. They have never seen a histogram.

Activity
Given an anemometer and a wind vane, students explore a virtual world where wind is modeled. With the help of a data-facilitator, students ask questions of the data. Students then analyze the data on their own, then make inferences and reason why those inferences would be important to deciding where to site a wind turbine. Students are directed towards other sources for wind data, such as NOAA ASOS.
