Description of the students in the class (achievement level, language, prior course work, typical level of engagement, etc):
Thirty one freshmen and one sophomore participated this year. These students are primarily college bound and did actively engage in the lessons.
The week prior to the STORE activities students were introduced to basic atmospheric science with lessons on the composition and layers of the atmosphere as well as pressure and energy transfer in the atmosphere. Lessons consisted of PowerPoint presentations and lab activities on: layers of the atmosphere; composition of the atmosphere; atmospheric pressure; nitrogen, oxygen, carbon and water cycles; formation & changes of the atmosphere’s composition since the Earth was formed (and how scientist’s determine this with ice core’s, etc.); movement of energy in the atmosphere (radiation, conduction, convection); the greenhouse effect & greenhouse gases. After the STORE lessons we covered atmospheric circulation is due to unequal heating and cooling of the Earth’s surface (land heats and cools faster than water); global winds are caused by pressure changes, convection, & the Coriolis effect; local winds are due to differential heating & cooling of land & water; climate is the average of weather conditions over a long period of time; climate is primarily classified by annual precipitation and daily temperature averages; three factors that affect climate are latitude, heat absorption & release, and topography of the region; ocean currents affect weather and climate; El Nino & La Nina affect the west coast precipitation; the rain shadow effect is obvious in the weather & climate of the Sierra Nevadas.
Prior to the STORE lessons the class and laboratory activities performed included making a foldable of the layers of the atmosphere and element cycles, demonstrations and activities related to pressure. After the STORE lessons we did activities on differential heating and cooling of soil and water, watching video clips on various related topics, as well as the Discovery channel movie, “Global Warming: What You Need to Know with David Brokaw”.
After my 2012 experiences with STORE & Google Earth I chose to incorporate a Google Earth introductory activity during my map unit in the fall semester. Students went to the library computer lab and downloaded the recently updated Google Earth to their personal school files. The following day we went back to the library and the students downloaded the STORE data files to their school files. They were then allowed to “play” with Google Earth and find their homes, the school, and other places of interest.
This year, 2013, students were introduced to the STORE project briefly on the Monday 3/18 prior to going to the computer lab and were given the Pre Assessment.
Tuesday 3/19 we went to the new computer lab and student groups received a full length copy of the Basic Lesson #2 Scafolded for reference, along with a shortened, slightly modified version: “Using Google Earth to Analyze the Connection Between Topography and Rainfall” which had the students search for information on average precipitation and average daily temperatures for the CA study area. Throughout the period most students were able to access and work with the data. None completed the activity on day one. Fortunately, Jason Westfall and Dan Zalles and Kathy Haynie were all available to assist students for the three days in the computer lab. Having extra help available was extremely useful, particularly that first day.
On Wednesday, 3/20 we went back to the lab. About half of the students needed to finish the first lesson. All started the second lesson, “Predicting the Future”. They were about evenly split with the projected changes in temperature and precipitation being higher (or lower) than their starting hypotheses. Students were very engaged in the activity.
On Thursday, 3/21, we finished up the computer portion of the lessons. All students finished the two lessons and many worked on the “STORE 2013 Wrap -Up” lesson created by Jason Westfall. All students completed this on Friday, 3/22. Students completed the Post Assessment as well.
Although the post-assessment results were not what I hoped for, nearly all students made improvements. Overall, I feel that this year went very well and students enjoyed the activities and learned more than the questions show. I plan on doing the same lessons next year.
Big ideas: / 1. Daily temperature is influenced by elevation (topography) & proximity to large bodies of water.2. Elevation (topography) influences average daily temperatures & precipitation amounts.
3. Future climate change can be projected from past data.
4. Data is more understandable with computer technology.
5. Weather & climate are not the same and vary by location.
State standard(s) addressed: / CA Earth Science Standards:
IE#1: Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other four stands, students should develop their own questions and perform investigations.
IE1, a. Select and use appropriate tools and technology( such as computer-linked probes, spreadsheets, and graphing calculators) to perform tests, collect data, analyze relationships and display data.
IE1, b. Identify and communicate sources of unavoidable experimental error.
IE1, c. Identify possible reasons for inconsistent results, such as sources of error or uncontrolled conditions.
IE1, d. Formulate explanations by using logic and evidence.
IE1, g. Recognize the usefulness and limitations of models and theories as scientific representations of reality.
IE1, h. Read and interpret topographic and geologic maps.
IE1, j. Analyze the locations, sequences, or time intervals that are characteristic of natural phenomena (e.g. relative ages of rocks, locations of planets over time, and succession of species in an ecosystem).
IE1, j. Recognize the issues of statistical variability and the need for controlled tests.
IE1, k Recognize the cumulative nature of scientific evidence.
IE1,l. Analyze situations and solve problems that require combining and applying concepts from more than one area of science.
IE1, m. Investigate a science-based societal issue by researching the literature, analyzing the data, and communicating the findings. Examples of issues include irradiation of food, cloning of animals by somatic cell nuclear transfer, choice of energy sources, and land and water use decisions in California, etc.
#6: Climate is the long term average of a region’s weather and depends on many factors.
6, a. Students know weather (in the short run) and climate (in the long run) involve the transfer of energy into and out of the atmosphere.
6, b. Students know the effects on climate of latitude, elevation, topography, and proximity to large bodies of water and cold or warm ocean currents.
6, c. Students know how Earth’s climate has changed over time, corresponding to changes in Earth’s geography, atmospheric composition, and other factors, such as solar radiation and plate movement.
6, d.* Students know how computer models are used to predict the effects of the increase in greenhouse gases on climate for the planet as a whole and for specific regions.
What do you intend the students to learn about this idea or be able to do with it: / 1. Average daily temperatures have less variation closer to the ocean than in the Central Valley or foothills of the Sierras.
2. Average daily temperatures are generally lower at higher elevations.
3. Average temperatures were lower in the past and are projected to continue to increase over the next decades.
4. Average precipitation is projected to decrease in many areas of California.
5. Computer models help scientists make sense of large amounts of collected data.
6. Climate change is real and humans are contributing to it.
Why it is important for students to know this (for example, in the schema of the broad course’s standards/ objectives or in terms of bigger educational/civic/social goals): / The appeal of this project to me, the instructor, is many layered. I believe that all students should be aware of: 1) the evidence for, and consequences of, climate change; 2) how and why precipitation varies in our state and what we should do as citizens to protect it; and 3) the computer technology available and how it is used for scientific analyses.
In addition to being part of California State Science standards, these concepts are critical to developing an informed citizenry able to understand that climate change will have far reaching impacts on our future in California. In their future, students will need to make decisions on how to mitigate the climate changes that are coming, including choices regarding water use and storage in California.
Finally, our local community college has an excellent geospatial information science program (and instructors!). The STORE project provides me with tools to interest students in that program, collaborate with the instructors there, and possibly help students find a future career.
Anticipated student misconceptions and difficulties understanding this: / 1. Climate is the same as daily weather.
2. All parts of California experience the same weather, both temperature and rainfall.
3. Students are not familiar with the program , nor do they utilize computers regularly at out school (except for word processing or internet research for papers or projects)
Teaching procedures (and reasons why): / 1. Lectures (PowerPoints following the textbook & State Standards): To give the foundation for understanding the lessons.
2. Computer laboratory time: To see actual data and gain familiarity with the technology
Formative assessment:
Specific ways of ascertaining students’ understanding or confusion around this idea (include likely range of responses): / 1. Completion of the activity worksheet. Some student responses to the end questions:
