Archaeologists study past human cultures through the excavation and analysis of artifacts. Archaeologists use a vocabulary specific to the field of archaeology to conduct and describe their work. Archaeologists use specific tools and processes to excavate artifacts. Archaeologists follow specific procedures to record their findings. Humans in the Meadowlands area used resources in their environment and consequently changed the environment. Most artifacts found in the Meadowlands area are from the landfills that covered the Meadowlands environment. Meadowlands area is reverting to a more natural state given recent and current environmental policies. Participants will learn how to: Work as part of an excavation team with assigned responsibilities. Use tools to excavate artifacts. Mark locations of artifacts using a grid overlay and map of the excavation site. Properly clean artifacts. Describe and classify artifacts according to possible use. Develop hypotheses about the culture of the people who left behind artifacts. Activities: Introduction to Archaeology PowerPoint / discussion (10 minutes) Universal Instructional Design (UID) – PowerPoint color contrast, font and size meet accessibility standards; white space, no more than 6 lines of text, no more than 6 words per line, images have alternate text tags. Copy of PowerPoint available in color (1 or 2 slides per page) in a 3-ring binder. Use of sound field system; assistive listening devices for those with hearing impairments or attention difficulties. Educator reads and describes images on slides. Excavation: (60 minutes) Hike to excavation site. Instruction on processes, procedures, use of tools, documentation. Excavation of artifacts using trowels and sifters. Have participants try out different procedures and roles within an excavation team, e.g. digger, recorder, cleaner, sifter, etc. Participants place their artifacts in designated bags. Recording of locations on grid. Participants mark the site of found artifacts with an X or a simple sketch of the artifact. UID – Educator explains entire excavation process to participants. Educator physically demonstrates and verbally describe the tools used to excavate while in classroom and at field site. Visual and written instructions provided to supplement verbal instructions and demonstration. Tabletop excavation containers are available to simulate excavation pit. A variety of each tool is available. Participants manually record results in journal, use pre-printed labels, or verbally record data using hand-held recorder. Journals with Verdana font and 18 pt. size, with visual and text descriptors, peel off response labels, large print, uncluttered design with white space. Working with the artifacts (classroom): (20 minutes) Cleaning of artifacts. Participants use brushes, and warm soapy water to clean artifacts. Recording, drawing and describing artifacts. Discuss artifacts with participants, eliciting words that describe appearance, materials, size, shape. UID – Educator explains all steps in the cleaning process. Educator physically demonstrates and verbally describes the process for cleaning artifacts. A variety of styles of each tool is available. Visual and written instructions provided to supplement verbal instructions and demonstration. Participants manually record results in journal, use pre-printed labels, or verbally record data using hand-held recorder. Journals with Verdana font and 18 pt. size, with visual and text descriptors, peel off response labels, large print, uncluttered design with white space. Making hypotheses about identification, purpose or use of artifacts. (15 minutes) UID – Participants work in small groups to examine and discuss artifacts. Educator displays and passes artifacts to each group, modeling how to make hypothesis (e.g. metal piece might be knob from cabinet; pottery shard might be piece of bowl) Educator elicits responses. Participants manually record results in journal, use pre-printed labels, or verbally record data using hand-held recorder. Journals with Verdana font and 18 pt. size, with visual and text descriptors, peel off response labels, large print, uncluttered design with white space. Extrapolating what the artifacts tell us about people who lived in the Meadowlands area 50 - 60 years ago. (15 minutes) UID – Educator displays and passes around artifact, modeling how to make hypothesis (e.g., excavated clam shell: people ate clams, had tools for opening clams, had method of transporting clams from ocean environment, etc.). Educator elicits responses. Program Modifications/ Adaptations Following are specific accommodations/adaptations and strategies found effective, and currently in use or being tested for use by specific disability groups in this program module. Cognitive Disabilities Content – Simplified program content. Learning Environment – Shorter walking route to field site; more time to move from site to site; shortened program; raised excavation site available. Limit number and type of artifacts for more simple analysis and classification. Materials – Simplified journals with images and single word descriptors; large size peel off picture and/or text labels for recording information in journals. Equipment/Assistive Technologies – Raking and scooping devices with easy to grip handles; long-handled raking and scooping devices. Variety of sifters. Teaching Strategies – use simple vocabulary; frequently repeat concepts; speak slowly; ask multiple choice questions (only giving them two options); and physically demonstrate how to use various tools. Break down information into small chunks. Instruct participants on purpose and use of equipment (for example, trowels) before introducing the equipment in the STEM content activity. When necessary, demonstrate, hand-over-hand, how to do an activity. Have participants work with a partner. Group subdivided into smaller groups (4 at a table, one educator per table). If possible, train partner staff first on all modules which enables them to better assist their participants. Mobility Disabilities Learning Environment – Shorter walking route to field site; more time to move from site to site; shortened program. Alternative indoor program with table top bins simulating excavation pits; adjustable tables. Materials - Larger journal page size attached to large clip board; large print and peel off labels. Dycem to keep materials in place on table surface. Equipment/Assistive Technologies – Raking and scooping devices with easy to grip handles; trowels with extendable handles for wheelchair users or those with physical access issues; clear plastic boxes to hold specimens on lap for viewing, writing lap boards; portable tables placed at outdoor field sites; hand lenses on neck lanyards; and large foldable magnifiers. Heightadjustable tables. Teaching Strategies – open-ended questions, some multiple choice questions, extra time to respond either verbally or with personal communication device; specially designed communication boards and flip books for non-verbal responses; additional time to execute activities. Participants subdivided into small groups (4 at a table) with one educator and an assistant. Flexible approach to all activities (e.g. eliminating activities or re-calculating time spent on each portion of the program; developing new methods for accomplishing physical tasks based on trial and error, participant or chaperone suggestion) Blind and Low Vision Materials - Journal and other documents enlarged to Verdana 20 pt.; documents converted to Braille; PowerPoint offered in a binder, with one slide per page; PowerPoint available in electronic, accessible formats for personal viewing following the scheduled program. Equipment/Assistive Technologies - Tactile models of trail and dig site. Alternative indoor program with table top bins simulating excavation pits; adjustable tables. Dycem to anchor materials to table top. Hand lenses on neck lanyards; and large foldable magnifiers. Tape recorders to verbally record data. Braille embosser and Braille translation software for converting text documents into Braille; Indiana University software for converting PowerPoint into accessible formats. Kenn – a - vision for enlargement of artifacts for viewing. Teaching Strategies - Educator reads what is on each PowerPoint slide, and verbally describes relevant pictures in detail. Careful presentation and demonstration of tools with sharp edges. Hand-on-hand assistance with excavation and cleaning. Verbal description of artifacts, including color, shape, material, etc. Deafness and Hearing Loss Materials/equipment – Sound field and assistive listening devices. Written and visual step by step instructions for all procedures and activities. Journals with peel off picture and/or text labels for recording information. Teaching Strategies – Use of interpreter(s), who has been provided with key vocabulary ahead of time. Educator speaks slowly and clearly, to accommodate interpreters, and those who lip read; educator stands in a central, front of room location so all participants who lip-read can clearly see the face of the educator. Educator physically demonstrates how to use various tools/equipment, waiting between steps for interpreter to complete translation, and to wait for any questions. Participants break up into small groups (4 or less) during activity, with assistant working with each group, and interpreters moving from group to group as needed. Educator refers to simplified and standard text and visual step-by-step instructions. Age-Related Limitations Note: All materials, equipment, assistive technologies, and teaching strategies described above would be implemented based on the functional ability /disability (cognition, mobility, hearing, vision) of the participant. Content: High level, age appropriate content, closely related to expected life experiences of participants. Learning Environment – Shorter walking route to field site; more time to move from site to site. Alternative indoor program with table top bins simulating excavation pits; adjustable tables. Materials - High level, high interest journals with large font, visually organized with a great deal of white space separating text, images, answer boxes. Communication boards with text and images serving as memory prompts, or for use in non-verbal response. Equipment/Assistive Technologies – Handheld magnifiers, large foldable magnifiers, sound field and assistive listening devices; tools with different types of handles / grips. Teaching Strategies – slower pace of instruction (especially with those individuals with aphasia), slower walk to the outdoor classroom site, allowing extended time to ask and answer questions. Use of whiteboard to write down key concepts during lecture/discussion phase of program. Relating science content to life experiences. . Participants break up into small groups (4 or less) during activity to encourage interaction and participation.
