Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

This course introduces methods for harnessing data to answer questions of cultural, social, economic, and policy interest. We will start with essential notions of probability and statistics. We will proceed to cover techniques in modern data analysis: regression and econometrics, design of experiments, randomized control trials (and A/B testing), machine learning, and data visualization.
We will illustrate these concepts with applications drawn from real-world examples and frontier research. Finally, we will provide instruction on the use of the statistical package R, and opportunities for students to perform self-directed empirical analyses.

This course draws materials from 14.310x Data Analysis for Social Scientists, which is part of the MicroMasters Program in Data, Economics, and Design of Policy offered by MITx Online. The MITx Online course is entirely free to audit, though learners have the option to pay a fee, which is based on the learner’s ability to pay, to take the proctored exam and earn a course certificate. To access that course, create an MITx Online account and enroll in the course 14.310x Data Analysis for Social Scientists.

This assignment asks students to write a data-rich policy brief, showing their ability to apply standard microeconomic models and contextualizing the policy debate with numeric evidence.

Background Scientific research in the 21st century is more data intensive and collaborative than in the past. It is important to study the data practices of researchers – data accessibility, discovery, re-use, preservation and, particularly, data sharing. Data sharing is a valuable part of the scientific method allowing for verification of results and extending research from prior results. Methodology/Principal Findings A total of 1329 scientists participated in this survey exploring current data sharing practices and perceptions of the barriers and enablers of data sharing. Scientists do not make their data electronically available to others for various reasons, including insufficient time and lack of funding. Most respondents are satisfied with their current processes for the initial and short-term parts of the data or research lifecycle (collecting their research data; searching for, describing or cataloging, analyzing, and short-term storage of their data) but are not satisfied with long-term data preservation. Many organizations do not provide support to their researchers for data management both in the short- and long-term. If certain conditions are met (such as formal citation and sharing reprints) respondents agree they are willing to share their data. There are also significant differences and approaches in data management practices based on primary funding agency, subject discipline, age, work focus, and world region. Conclusions/Significance Barriers to effective data sharing and preservation are deeply rooted in the practices and culture of the research process as well as the researchers themselves. New mandates for data management plans from NSF and other federal agencies and world-wide attention to the need to share and preserve data could lead to changes. Large scale programs, such as the NSF-sponsored DataNET (including projects like DataONE) will both bring attention and resources to the issue and make it easier for scientists to apply sound data management principles.

This video segment, adapted from Decision in the Streets by civil rights filmmaker Harvey Richards, portrays the interracial protests that took place in San Francisco in 1963-64.

This page explains the position in defense of the Black Hills. The purpose is to ensure that the Fort Laramie Treaties are re-upheld.

In this video segment adapted from Navajo Technical College, meet a dendroclimatologist who studies the relationship between precipitation and tree growth in the Navajo Nation.

In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

This lesson provides experience working on a real-life scenario by allowing students the opportunity to use topographic maps to design a hiking trail system based on access from road, range of habitats, and other specified criteria. They will also complete a data sheet and produce an informational brochure.

Students are challenged to design a permanent guest village within the Saguaro National Park in Arizona. The design must provide a true desert experience to visitors while emphasizing sustainable design, protection of the natural environment, and energy and resource conservation. To successfully address and respond to this challenge, students must acquire an understanding of desert ecology, environmental limiting factors, species adaptations and resource utilization. Following theintroduction, students generate ideas and consider the knowledge required to complete the challenge. The lectures and activities that follow serve to develop this level of comprehension. To introduce the concepts of healthy ecosystems, biomimetics and the importance of sustainable environmental design, students watch three video clips of experts. These clips provide direction for student research and challenge design solutions.

In this problem-based learning (PBL) activity, students take on the role of a student research scientist and explore the role of solar energy in determining climate, focusing on the urban heat island effect. Students conduct research and compare temperatures between two cities, and determine the factors that are responsible for the difference exhibited between them. The lesson is supported by teacher notes, answer key, glossary and an appendix with information about using PBL in the classroom. This is the third of three activities in Investigating the Climate System: Energy, a Balancing Act, and serves as an authentic assessment for all three modules.

Students are asked to determine the break even profit point for a service to be offered on campus, using an online break even calculator.

This article highlights lesson plans and activities that help elementary students develop map skills as they learn earth science concepts.

This course provides rigorous introduction to core microeconomic issues in economic development, focusing on both key theoretical contributions and empirical applications to understand both why some countries are poor and on how markets function differently in poor economies. Topics include human capital (education and health); labor markets; credit markets; land markets; firms; and the role of the public sector.

This article provides an overview of differentiated instruction and resources for teachers looking to differentiate science and literacy content in the elementary classroom.

This article includes a menu of post-reading activities for use with any nonfiction text. Students spend $50 on their choice of activities.

In this unit, students make regular journal entries about a plant/animal/insect community in the natural area around our school and use this to create a Non-fiction Class Book. They also interview family/resources to discover, record and present stories about human relationships with nature from their culture(s).

This article describes how to use art projects to help students learn science concepts and how this integration helps students with language-based learning disabilities.
