River: A Living System. Part 3: Observation Logs During our study of rivers, we are going to be learning about the ways that a river is a living system. We will spend time each week at the river looking at the different aspects that are part of the system. You will observe and record what you find, using an observation study log sheet. Make sure you remember to record what you see, what you hear, what you smell and what you wonder about. Your wonderings can lead to new learning. Be sure to date each entry and record any changes from one observation to the next. You may also want to include a sketch of things you see and to use science vocabulary in your descriptions.

Each observation entry took place during a class session of about 60 minutes. Context The observation log is an ongoing part of a river study unit that took place over four to six weeks. Weekly trips to our local Thatcher Brook for observation and field studies, followed by classroom lessons on different aspects of the river system, guided the observation process and introduced new science vocabulary and concepts. Students kept observation logs, dating each entry when we visited the brook. At the end of the study, students were able to self-evaluate their growth in observation skills, using the observation rubric introduced in Part 1, by reviewing their log entries. Observation logs became part of each student’s river study portfolio. What the Task Accomplishes Ongoing observation logs teach, reinforce and assess the skills of observation, recording data, and communication. Students use their earlier observations and peer feedback to learn how to improve their recording of what they see. How the Student Will Investigate During each trip to the river, students were asked to record observations using study log sheets. Each student had a log sheet, a clipboard and about an hour to explore, locate and record. Students were reminded to include details, provide enough information about what was actually observed, use several of their senses and try to use science vocabulary to help them to write detailed descriptions. Interdisciplinary Links and Extensions Science Return to the river at various times of year to observe and record seasonal changes. Using field guides, identify trees and shrubs along the banks of the river. Collect and identify leaf, wild flower, seed, and twig samples for field logs. Make simple leaf presses for pressing and drying leaves and wild flowers collected. Also see other parts of this unit of study. River: A Living System.

We used the watercolors to illustrate haiku that we wrote while there. Use phrases from observation logs as lines of haiku or other poetry. (Use the student samples included with this task to model using phrases from observations to write a class or group poem.) Mathematics Take tools along, such as compasses, thermometers, metric rulers, calipers, etc., to measure and record additional data. Teaching Tips and Guiding Questions Ongoing observation logs can help improve student learning and skills if they 1) continue to build upon the students’ current skill levels, 2) provide clear criteria for the expected standard and an opportunity to practice self-assessing their work, and 3) empower students to set goals for improved performance. Key questions are: • • • • • • • • • Did you use several of your senses to observe? Did you date your entry? How does this observation compare to the last one you wrote? Which journal log recordings give the clearest information? Does your observation include something unusual or interesting? Does your observation include something surprising? Does your observation make you want to learn or explore more? Does your observation make comparisons? include sizes? colors? Does your observation use specialized science terms to describe what was observed? What would make your observation even better next time? Concepts to be Assessed (Unifying concepts/big ideas and science concepts to be assessed using the Science Exemplars Rubric under the criterion: Science Concepts and Related Content) Life Science – Structure and Function; Evolution, Diversity and Adaptations: Students observe anatomical differences in organism. Students understand that all organisms are living systems, that each distinct structure has a set function that serves the organism, and that species acquire their unique characteristics through biological adaptations. Students classify and compare organisms, using prior knowledge, and understand what to look for (size, shape, texture, structure) when observing organisms. Earth Science – Earth Structure and System: Students observe landforms and their relationship to the water cycle and local water systems. Students show specific differences in land forms, weather conditions, plants and/or organisms and describe characteristics in terms of a combination of traits. River: A Living System. Part 3: Observation Logs Copyright 2007, Exemplars, Inc. All rights reserved. 4 of 12 Science in Personal and Societal Perspectives – Populations, Resoures and Environments: Students can explain that human activities have an impact on natural systems and that changing human behaviors can lessen or increase the impact on ecosystems. Scientific Method: Students determine patterns and/or which kinds of change are happening over time (change and constancy, patterns). Students describe cause-effect relationships with some justification, using data and prior knowledge (cause and effect). Mathematics: Students understand and represent size and proportional differences. Skills to be Developed (Science process skills to be assessed using the Science Exemplars Rubric under the criteria: Scientific Procedures and Reasoning Strategies, and Scientific Communication Using Data) Scientific Method: Using prior knowledge, using scientific reasoning, observing, predicting/hypothesizing, collecting and recording data, comparing, inferring, drawing conclusions, communicating findings, challenging misconceptions and raising new questions. Other Science Standards and Concepts Addressed Scientific Theory: Students look for evidence that explains why things happen and modify explanations when new observations are made. Life Science – Structure and Function; Regulation and Behavior; Populations and Ecosystems: Students describe and group organisms using physical characteristics and anatomical differences. Students understand that living things are living systems and that each type of cell, tissue and organ has a distinct structure and a set of functions that serve the organism. Students understand that living things are found almost everywhere in the world and are interdependent. Life Science – Evolution, Diversity and Adaptations: Students observe species and many of their unique characteristics, acquired through biological adaptations, which include changes in structures, behavior and/or physiology that enhance survival in an environment. Science in Personal and Societal Perspectives – Populations, Resources and Environments: Students observe that human actions can cause changes in vegetation, ecosystems and/or entire landscapes and that resource demands can limit the growth of populations in specific ecosystems. Students observe that human activities have an impact on natural systems and that changing human behaviors can lessen the impact on ecosystems. Earth Science – Earth’s History: Students look for evidence of the earth’s processes, including erosion, movement of lithospheric plates and changes in atmospheric composition. Earth Science – Earth Structure and System: Students observe that landforms are a result of a combination of constructive (crustal deformation, volcanic eruption, deposition) and River: A Living System. Part 3: Observation Logs Copyright 2007, Exemplars, Inc. All rights reserved. 5 of 12 destructive (weathering and erosion) forces. Students can explain that water circulates through crust, oceans and atmosphere in what is known as the “water cycle”: water evaporates from the earth’s surface, rises and cools as it moves to higher elevations, condenses, and falls to the surface where it collects in lakes, rivers, oceans and the soil. Suggested Materials For each observation, students may need paper for additional drawings, pencils, clipboards and study log worksheets. Field guides are not necessary, but do provide additional information while in the field. The observation rubric (See "River: A Living System. Part 1") can be used for assessing log entries back in the classroom. Colored pencils are also optional; markers are not recommended. Possible Solutions The content of each individual entry will vary unless a specific purpose for observation is set each time. Students will date, observe and record, using an observation study log sheet. They should record at least one thing that they see, hear, smell and wonder about. Observations should be detailed enough to include some of the following: colors, sizes, numbers (e.g., 6 legs) comparisons, or descriptive modifiers. Extended thinking may be evidenced by noting any changes from one observation visit to the next, using scientific terms, and/or making connections to prior learning or big ideas in science. A sketch of things observed may also be included. Note: The Novice and Apprentice levels are from earlier observations. All students showed improvement from earlier to later observations. The Practitioner and Expert samples are from later observations. Task-Specific Assessment Notes Novice This student’s log contains the minimal number of observations. Information is general, vague and lacking in details. There are no conceptual connections between things noted or wondered about. The student does not attempt to use any science terms in the recordings. Apprentice This student’s log is well-organized with numerous observations for each category, yet lacks details. Observations imply a “wide-angle pan” of the entire area – including highways, people, bugs, plants, the wind, etc. No specific descriptors are provided; however, there is some evidence that the student attempts to use some science terms (e.g. habitat) and collect data. The wonderings seem to be related to a central focus (water) – evidence of some conceptual understanding and reasoning. River: A Living System. Part 3: Observation Logs Copyright 2007, Exemplars, Inc. All rights reserved. 6 of 12 Practitioner Student #1 This student’s log entry is complete and detailed. There is an attempt to use science vocabulary and specific qualifiers in the written description. A small drawing is included to help explain the design on a waterpenny’s back. The “wondering” is linked to field observations and seems to be built upon prior knowledge and experience about the nature of water bugs. Student #2 This student’s log entry is complete and detailed. There is an attempt to use science vocabulary and specific qualifiers throughout the written description. The “wondering” is linked to field observations and is followed up with an identification, probably using a field guide. Expert This student’s entry is complete and detailed. The student uses extensive science vocabulary and specific qualifiers throughout the written description. There is clear evidence of scientific reasoning and use of prior knowledge in both the description and wonderings, which are linked to observations and the big ideas of science. Data include comparative measurements of temperature from two different observations. River: A Living System. Part 3: Observation Logs Copyright 2007, Exemplars, Inc.
