Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

Changes in voting qualifications and participation, the election of Andrew Jackson, and the formation of the Democratic Party"”due largely to the organizational skills of Martin Van Buren"”all contributed to making the election of 1828 and Jackson's presidency a watershed in the evolution of the American political system.

"Since 1991, the international Banff Classification has been revisited every 2 years to integrate advances in clinical research into best-treatment practices for organ transplantation. At the 2017 Banff conference, 479 delegates from 23 countries reviewed two seminal concerns in the kidney-transplant field: how T cell-mediated rejection is related to inflammation in areas of interstitial fibrosis and tubular atrophy, and the evolution of molecular diagnostics, particularly for identifying antibody-mediated rejection. These discussions prompted significant updates to the Banff scheme. The relationship between i-IFTA severity and graft survival has been well established. Despite this, i-IFTA has previously been excluded as a diagnostic criterion of TCMR. Recent findings, however, suggest that inflammation in IFTA can be a manifestation of chronic active TCMR, particularly when other features of T cell-mediated alloimmunity, such as tubulitis, are present..."

Why are living things different from one another? This unit on genetics starts out with students noticing and wondering about photos of two cattle, one of whom has significantly more muscle than the other. Students figure out how muscles typically develop as a result of environmental factors such as exercise and diet. Then, they work with cattle pedigrees, including data about chromosomes and proteins, to figure out genetic factors that influence the heavily muscled phenotype and explore selective breeding in cattle.

This unit is part of the OpenSciEd core instructional materials for middle school.

In 2018; the landscape of services for children and families being served in California Child Welfare Services has continued to evolve. One recent evolution is the use of Child and Family Teams as a vehicle for team planning. Child and Family Teaming (CFT) must integrate practices; services and supports for children; youth; non-minor dependents (NM Ds) and families in care. Two of the major practices to integrate with the CFT mandate include Safety Organized Practice (SOP) and Team Decision-Making (TDM) meetings. SOP is a collaborative practice approach that emphasizes the importance of teamwork in child welfare; and TDM is a facilitated team meeting structure to address placement issues for children involved or potentially involved in foster care. This workshop will focus on the promising practices and art of integrating SOP and TDM into a CFT process. Participants will leave with increased capacity to create one teaming process that meets the needs of the child; youth; NM D; parent; family agency and community.

This is the third and last part of a webinar series on InterPro which is held between May 6th 2020 and May 20th 2020.

InterPro is a database that helps users to understand the possible functions of proteins sequence by identifying what family it belongs to or what domains and motifs it contains. To deal with the growing volume of protein sequence data and an increasing demand to retrieve subsets of the data, often via programmatic access, the InterPro website has been entirely redesigned. It provides additional features and more flexibility in querying, presenting and retrieving data. The website relies on an Application Programming Interface (API) which can also be utilised by users for direct access to the data.

This webinar describes how the InterPro data is structured in the API, and how it could be accessed programmatically for further bioinformatics analyses.

You can access the slides via GitHub.

Who is this course for?
This webinar is aimed at scientists and bioinformaticians, with basic programming knowledge, who are interested in accessing the InterPro database programmatically.

This segment from Swift: Eyes through Time traces the history military officers and engineers discovering a strange phenomenon in the sky that astronomers now know are gamma-ray bursts.

In this field-based exercise, students were given a tour of an abandoned mine site and asked to utilize a set of field measurements to describe the spatial details of metal transport. This drew on previous experience with field measurements and prompted them to work together to solve an observed chemical evolution of a contaminated brook. The exercise is an excellent example for students to bring together acid-base chemistry, redox chemistry, and thermodynamic concepts together to describe a reasonably complex system. The field component was completed in a full day, but we will be expanding this next fall for a 2 day exercise (weekend). The exercise was coupled with subsequent labs to complete analysis of the water samples and accomplish speciation calculations using PHREEQCI.

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

In this project, each student will be assigned to a group of three to four students. Each group will be given random character description cards. These characters will be treated as the first generation in a fictitious town. The cards will include specific genetic traits, skills, jobs, as well as reference if the character suffers from type 2 diabetes. Students will need to use the character cards to author and illustrate a short story about the fictitious town which follows at least three generations of the families in the cards. Students must also include pedigrees for a minimum of three traits as well as diabetes as evidence of inheritance.

"Actinobacteria are some of the most widely distributed bacteria in soils and are well known for their ability to degrade plant residues in pure culture in the laboratory. Yet, despite the importance of microbe-driven decomposition to carbon sequestration in terrestrial systems, their importance and specific activity across diverse environments in the field are unknown. Researchers recently evaluated the ecophysiological roles of Actinobacteria in rice straw residue decomposition in a series of field and microcosm experiments. They found that although Actinobacteria represented only 4.6% of the total bacterial abundance, they encoded 16% of the total carbohydrate-active enzymes (CAZymes) involved in the breakdown of carbohydrates. The researchers also found that Actinobacteria taxonomic and functional compositions were relatively stable during straw decomposition and that the importance of Actinobacteria in decomposition increased as soil fertility decreased..."

The United States has a long history of activists seeking social, political, economic, and other changes to America—along with a history of other activists trying to prevent such changes. American activism covered a wide range of causes and utilized many different forms of activism. American sociopolitical activism became especially prominent during the period of societal upheaval which began during the 1950s. The African American civil rights movement led the way, soon followed by a substantial anti-war movement opposing American involvement in the Vietnam War, and later by vigorous activism involving women’s issues, gay rights, and other causes. The United States remains a land of nearly constant change, and activists play a significant role in the ongoing evolution of American democracy. It seems likely that Americans will remain enthusiastic activists in the future. This exhibition is part of the Digital Library of Georgia.
