Students explore the tools and techniques of meteorologists, geologists, and astronomers in this unit. As meteorologists, they gather weather data and interpret weather maps. As geologists, they learn to read the story of a rock and then how to identify it. As astronomers, they experiment with lenses to understand simple telescopes and then go on to learn about the latest advances in astronomy.

Results of similar scientific investigations seldom turn out exactly the same. Sometimes this is because of unexpected differences in the things being investigated, sometimes because of unrealized differences in the methods used or in the circumstances in which the investigation is carried out, and sometimes just because of uncertainties in observations. It is not always easy to tell which. Scientific investigations may take many different forms, including observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments. Investigations can focus on physical, biological, and social questions. Results of scientific investigations are seldom exactly the same, but if the differences are large, it is important to try to figure out why. One reason for following directions carefully and for keeping records of one’s work is to provide information on what might have caused the differences. Throughout all of history, people everywhere have invented and used tools. Most tools of today are different from those of the past but many are modifications of very ancient tools. Measuring instruments can be used to gather accurate information for making scientific comparisons of objects and events and for designing and constructing things that will work properly.

Lesson Outline
Explain that they will be studying different areas of Earth Science over the next several weeks.
Introduce the word "Meteorology." Discuss that it comes from the Greek words for astronomical phenomenon and study of.
Discuss what students already know about the weather. List what the weather reporter mentions in a weather report.
Discuss each part of the weather report. Include the tool used and what it tells us about the weather.

Go outside and find the temperature in and out of the sun and wind, up high and near the ground. Record information on Student Booklet page 2.
Before leaving for the day, arrange the thermometers all over the room —near and far from the heater/ air conditioner/swamp cooler, near the ceiling, near the floor, near the door, and far from the door.. As soon as students arrive the next morning, read all the thermometers and map the temperature of the room. During the day the movement of students will tend to mix the air and that leads to more uniform temperatures. If the temperatures do not vary very much, consider reading the thermometers yourself as soon as you arrive.
The Next Day: After reading the temperatures and recording the data, allow students to work in small groups to make sense of the numbers. Are there trends? Does the data make sense? Are additional trials necessary? Discuss that the real work of scientists comes from the interpretation of the data.

If possible, allow students to find the dew point. In the desert southwest, the dew point is often below freezing so students are not able to measure it. (If it's close to freezing, adding some salt to the water will allow students to complete the activity.) If it is not possible to find the dew point, check out www. weather.com or your local television station's web site to find the dew point for your zip code. Be sure to do the dew point activity when possible.
Lesson 4: Weather Patterns
Lesson 4 -Weather Patterns
OBJECTIVE
Students learn how to read weather maps to determine weather patterns.
AAAS BENCHMARKS COVERED*
Scientists’ explanations about what happens in the world come partly from what they observe, partly from what they think. Sometimes scientists have different explanations for the same set of observations. That usually leads to their making more observations to resolve the differences. Science is an adventure that people everywhere can take part in, as they have for many centuries. Clear communication is an essential part of doing science. It enables scientists to inform others about their work, expose their ideas to criticism by other scientists, and stay informed about scientific discoveries around the world. Mathematics is the study of many kinds of patterns, including numbers and shapes and operations on them. Sometimes patterns are studied because they help to explain how the world works or how to solve practical problems, sometimes because they are interesting in themselves.

AAAS BENCHMARKS COVERED*
Waves, wind, water, and ice shape and reshape the earth’s land surface by eroding rock and soil in some areas and depositing them in other areas, sometimes in seasonal layers. Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks. Soil is made partly from weathered rock, partly from plant remains—and also contains many living organisms. Heating and cooling cause changes in the properties of materials. Many kinds of changes occur faster under hotter conditions. Materials may be composed of parts that are too small to be seen without magnification.

AAAS BENCHMARKS COVERED*
The patterns of stars in the sky stay the same, although they appear to move across the sky nightly, and different stars can be seen in different seasons.
Telescopes magnify the appearance of some distant objects in the sky, including the moon and the planets. The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye. Planets change their positions against the background of stars. The earth is one of several planets that orbit the sun, and the moon orbits around the earth.
