3 Know your Earth video v=d2kh_z720ia

4 Overview Web based lessons (90 minutes) Problem solving Use real NASA data Set to the National Education Standards

5 My NASA Data Project National Standards: Math: Data Analysis and Probability Science Content: D Earth and Space Science Technology: Abilities for a Technological World AP Environmental Science Topics: Atmospheric circulation Solar electricity Solar energy Solar intensity and latitude

6 Possible ways to use lessons Analyzing graphs Solar energy, electricity and electromagnetic spectrum Science research classes as data analysis lesson Identifying geographical locations and climate

7 Has any one ever used the MY NASA DATA lessons in their classroom? Yes X No

8 Data Collection 15 Earth Observing Satellites Information on: Atmosphere Biosphere Cryosphere Oceans Land Surface

9 Terra Collect information on Earth s changing climate. AQUA Collecting information on water in the Earth system Studies the fluxes of radiation from the Sun and From the Earth that combine to constitute the Earth s radiation balance. CERES Sensor- Cloud and Earth s Radiant Energy System Measure the total thermal radiation budget

10 Seasonal Changes in Energy orldofchange/decadaltemp.php

11 Let s pause for questions

12 My NASA Data

13 Featured Lesson Solar Cell Availability from Around the Country Purpose: To determine areas of the country which are most likely to produce solar energy by analyzing differences in incoming solar radiation graphs. Introduce as a rock star tour.

14 What do we need to know? Basic understanding of Solar Cells Be able to convert latitude and longitude into a city-state location Understand solar radiation

15 Solar Cells On a bright, sunny day, the sun's rays give off approximately 1,000 watts of energy per square meter of the planet's surface. -Photovoltaic solar pane array -Most are made of Silicon ( semiconductor)

17 Monthly Surface All-Sky Short Wave Downward Flux data is used to generate the resultant plots. This data is gathered using the CERES instrument on the Terra and Aqua satellites Parameter being used Aqua Terra

18 Earth s energy Budget

19 Computer lab Materials Classroom with only a few computers Classroom with only 1 computer connected to a video projector The MY NASA DATA web site has tips on classroom management for the use of the lessons

22 Congratulations! You have finally made it. You are now the star you always wanted to be. However, the life of a rock star requires months on the road. Luckily you have plenty of money and a very nice 40 long motor home whose electricity is powered by solar panels. Life will change, and being successful means you can t always live at home. Your manager requires you to do the following things

23 Constraints For stability, you will live part of every year in Sheridan, Wyoming. Since your performances take you to various parts of the country throughout the year, you must live in at least one other place, but you may only live in a maximum of 4 places throughout the year. Every place you live must have an average monthly sunlight of 100 watts/m 2 in order to run your needed electrical power for your home. You must live in the United States; however, you may travel outside of the country to get to your destination.

24 Determine the following: Where will you live each month of the year? How does the monthly average solar radiation compare to Sheridan? Find one place you might like to live during a particular season, but are unable to do so due to low solar radiation levels.

25 Procedures 1. Using My NASA Data Live Access Server (LAS) Found under Data access on the MY NASA Data home page Select the LAS advanced ( for high school students)

43 Let s try it out, rock stars Determine the following: Where will you live each month of the year? How does the monthly average solar radiation compare to Sheridan? Find one place you might like to live during a particular season, but are unable to do so due to low solar radiation levels. Remember your constraints: Must live part of year in Sheridan, WY Live one other place during the year; maximum of 4 places Must have average sunlight of 100 watts/m2 You must live in the US
