This is a lesson about representative sampling. When given parts of the Hubble Deep Field image, learners will count the number of galaxies in one sample section of the image. Then, they will calculate how many galaxies there are in each whole image and how many objects the Hubble Space Telescope could see in the entire Universe. This is Activity H-6 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase.

Learn how to build a strong foundation for your Bee Program! Our most successful programs begin with a layer of lessons and curriculum. Here we share exactly how to start a Bee Program and grow from the bottom up! Whether or not you have live bees on your campus, this will help to grow a community around your buzzworthy educational endeavors!

The folders in this Group will provide curriculums, virtual field trips with lessons, suggested Citizen Science Projects, book clubs for kids with lessons, and relevant webinars and recordings to help any educator deliver quality instruction. All of our offerings have teacher guides, are mapped to the standards, and are easily adapted to digital platforms.

We recommend the educator work through each level of the How to Start + Grow Your Bee Program Pyramid by exploring the offerings within each Folder. The resources build on each other as the educator and students move through this learning pathway.

Edmodo, as an LMS being used worldwide, has been integral to those who got exposed to its utility, even once. Edmodo has an assessment and evaluation segment as well where the teacher can create and execute a quiz based assessment. Besides giving assignments and grading them, the Quiz feature gives us an opportunity to conduct a real-time, online assessment.

Il volume rappresenta la tappa finale della prima stagione di implementazione del Progetto ABACUS (giugno 2019 - settembre 2020), sostenuta dal finanziamento pubblico garantito dalla Regione Siciliana e dalla Presidenza del Consiglio dei Ministri. In tal senso, la pubblicazione raccoglie sia una sezione di materiali di discussione critica sul percorso progettuale e sui primi esiti maturati, sia una ricca parte di contributi tematici offerti da referenti istituzionali, studiosi ed esperti, docenti accademici e ricercatori, professionisti e rappresentanti di organismi del Terzo settore Sono state così affrontate ed esaminate differenti tematiche e problematiche socio-culturali e socio-economiche, e prospettive e approcci metodologico-operativi tra loro affini e convergenti, che si sviluppano a cavallo delle politiche sociali, giovanili e culturali, della progettazione sociale e culturale, dell'innovazione sociale e della diversità culturale, in differenti contesti socio-territoriali siciliani e italiani, con una particolare attenzione per quelle iniziative che rappresentano casi paradigmatici in cui le istanze istituzionali, della ricerca, dell'educazione e della formazione si incontrano con le aspettative dei pubblici differenziati e, specialmente, delle giovani generazioni, anche sull'orizzonte della innovazione dell'occupazione giovanile.

This video discusses impacts that the Eastern US is experiencing due to climate change. It describes the seasonal shifts that may affect tourism in New England, extreme heat in the Southeast, how rising sea level affects coastal areas, changes in hurricane intensity, the spread of invasive species and disease, as well as other topics.

This video features Katharine Hayhoe presenting a lively discussion of impacts that the Midwestern US is experiencing due to climate change. It steps through evidence for how climate change is affecting agriculture, tourism, drought and flood, water cycles and freshwater availability, the spread of invasive species and disease, as well as other topics.

This short video focuses on how the melting of snow creates a more sticky substance that is easier to make snowballs with.

In this exercise, crystal structure data for a variety of unknown minerals are downloaded and entered into a visualization program (either XtalDraw or CrystalMaker). Through a series of directed questions for each unknown, students investigate and manipulate the crystal structure to gather information about its possible identity. This exercise builds on a wide variety of content normally covered over an entire introductory mineralogy course, and could be used as a self-study exercise to help mineralogy students prepare for a comprehensive final exam.

Students will gain insight into the influence of the Enlightenment on American society and government by comparing Neoclassical objects from the Getty collection to American civic architecture of the time.

This audio slideshow examines the changes in the ecosystem that will occur to the Arctic due to increasing temperatures and disappearing sea ice.

This art history video discussion examines the "Mihrab" (prayer niche), 1354--55 (A.H. 755), just after the Ilkhanid period, Isfahan, Iran, polychrome glazed tiles, 135-1/16 x 113-11/16 inches / 343.1 x 288.7 cm (Metropolitan Museum of Art, New York).

This task asks students to identify which of the six polygons have the same area. Students may complete the task using a variety of techniques including decomposing shapes, using transformations (rotations, reflections, translations) to move one or more parts of the figure to another part to more easily calculate the area, enclosing the polygon inside a larger rectangle and then subtract the areas of the "extra" pieces, etc.

In this visualization, students can explore North American fossil fuel CO2 emissions at very fine resolutions of both space and time. The data is provided by the Vulcan emissions data project, a NASA/DOE funded effort under the North American Carbon Program.

Students will create a drawing from a written description and examine and discuss how European artists from the past created images of China that combined imagination with written descriptions and limited visual imagery.

For many Americans today, snapping a photo is as easy as pulling out a smartphone. However, that digital photo is the result of decades of experimentation and development, from first forays into bulky and difficult-to-use professional cameras to instant-photo Polaroids. Since the advent and eventual commercialization of photography throughout the nineteenth century, cameras have continuously redefined the American public’s conception of how images and history can be captured and shared. Looking to the early cameras of the 1800s to today’s cell phones and social networking apps, this exhibition explores how the personal camera has shaped American consciousness and culture over the course of its development. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Dr. Joan E. Beaudoin's course "Metadata in Theory and Practice" in the School of Library and Information Science at Wayne State University: Ellen Tisdale, Rachel Baron Singer, Amanda Seppala, Michell Geysbeek, and Jay Purrazzo.

December 2013 marks the 80th anniversary of the end of Prohibition, the period between 1920 – 1933 when the manufacture, transport and sale of intoxicating liquors was illegal in the United States. The 18th Amendment to the Constitution, ratified in 1919, was the crowning achievement of a temperance movement that had been building in this country since the late 1700s. Alcohol consumption had peaked to a high of about 7 gallons per person in the early 1800s (compared to less than 3 gallons today), with recognized health and societal consequences. But the new laws were difficult to enforce, due to general unpopularity and the profits that could be made through circumventing the law. Demand for alcohol remained high, and organized crime and corruption flourished. Loopholes and exemptions also allowed home wine production, and prescriptions for medical alcohol rose dramatically. Enforcement difficulties, popular resistance, and economic pressures associated with the Great Depression all contributed to efforts to repeal Prohibition. In 1933, the 21st Amendment ended national prohibition and returned responsibility for alcohol regulation to the states.
