All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

Students learn about atoms and their structure (protons, electrons, neutrons) — the building blocks of matter. They see how scientific discoveries about atoms and molecules influence new technologies developed by engineers.

At the beginning of a course-based research project, each student in a research team is asked to read primary literature related to the team investigation. A mix of provided readings and readings found by the students builds the team content knowledge concurrent with team work on research design and data collection. Students reflect and report on the readings in an annotated bibliography, which is a graded assignment in the course.

This video module presents an introduction to cryptography - the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrypt messages. There are no prerequisites for this lesson, and it has intentionally been designed in a way that can be adapted to many audiences. It is fully appropriate in a high school level math or computer science class where the teacher can use it to motivate probability/statistics or programming exercises. nteractive lesson, students will learn to build the cryptography devices and will learn how to send and ''crack'' secret messages.

This activity involves building crystal structure ball models in order to strengthen students' understanding of crystalline order, relative atomic size, atomic coordination, crystal chemistry, and crystal symmetry.

Designed as a core or supplementary text for upper elementary, middle and high school teachers and students, Building Democracy for All offers instructional ideas, interactive resources, multicultural content, and multimodal learning materials for interest-building explorations of United States government as well as students’ roles as citizens in a democratic society. It focuses on the importance of community engagement and social responsibility as understood and acted upon by middle and high school students—core themes in the 2018 Massachusetts 8th Grade Curriculum Framework, and which are found in many state history and social studies curriculum frameworks around the country.

Urban design, inequality and segregation are strongly connected.

Cities around the world, from the Global South to the Global North, are facing a rise in inequality and socio-economic segregation. The wealthy are increasingly concentrating in the most attractive urban areas and poverty is spreading to the suburbs. Rising levels of segregation have major consequences for the social sustainability of cities and leads to unequal life opportunities depending on where in the city you live.

In this course, aimed at a broad range of professionals, from urban planners and architects to geographers, you will learn what the main drivers and indicators of urban inequality and segregation are, using examples from cities from all over the world. You will learn how segregation is measured, how to interpret the results of the analyses of segregation and how to relate these insights to urban design. With this knowledge, you will be able to analyze how these issues may be affecting your local environment.

Additionally, we will present some historical examples of how urban design has played a role shaping spatial inequality and segregation in a selection of case study cities. This will help you to get a better understanding of how urban design can reduce spatial inequality and segregation.

The course is taught by the editors of the new SpringerOpen book “Urban socio-economic segregation and income inequality. A global perspective” and senior experts from the Urban Design section of TU Delft, which is ranked number 2 in the QS World University Rankings in the field of Architecture.

This book offers a web-based multimedia platform to enable students in Architecture, Civil Engineering, and Construction Engineering to learn fundamentals of BIM using Revit and be able to create building architectural, mechanical and structural models, develop construction documentation and analyze building performance. The platform include: book chapters on detailed Revit instructions and videos.

The book presents a coherent theory of building information, focusing on its representation and management in the digital era. It addresses issues such as the information explosion and the structure of analogue building representations to propose a parsimonious approach to the deployment and utilization of symbolic digital technologies like BIM. It also considers the matching representation of AECO processes in terms of tasks, so as to connect to information processing and support both information management and decision taking.

Students build their own small-scale model roller coasters using pipe insulation and marbles, and then analyze them using physics principles learned in the associated lesson. They examine conversions between kinetic and potential energy and frictional effects to design roller coasters that are completely driven by gravity. A class competition using different marbles types to represent different passenger loads determines the most innovative and successful roller coasters.

Building Oscillation Seismic Simulation, or BOSS, is an opportunity for learners to explore the phenomenon of resonance for different building heights while performing a scientific experiment that employs mathematical skills. They experience how structures behave dynamically during an earthquake.

The city of Fort Collins, Colorado, found a win-win solution to problems it faced with 100 acres of abandoned property. The city now enjoys new green space, improved floodwater management, and a boosted economy.

Students in an area remote from igneous and metamorphic rocks wrote papers on the properties of locally used building stones and gave a walking tour in which they presented their results.

This lesson highlights the changing relationship between the city center and the suburb in the postwar decades, especially in the 1950s. Students will look at the legislation leading up to and including the Federal Highway Act of 1956. They will also examine documents about the history of Levittown, the most famous and most important of the postwar suburban planned developments.

This assignment, depending on the level and depth of implementation, seeks to challenge students by asking them to look beyond "greenwashed" advertisements and buzzwords to grapple with what sustainability means, whether it can be achieved, and what kinds of questions communities must confront in a search for sustainability.

Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.

Educators with an interest in hands-on science, technology, engineering and mathematics (STEM) disciplines will receive introductory instructions on how to design, engineer and build a fully functional underwater ROV.

Students investigate the weather from a systems approach, learning how individual parts of a system work together to create a final product. Students learn how a barometer works to measure the Earth's air pressure by building a model using simple materials. Students analyze the changes in barometer measurements over time and compare those to actual weather conditions. They learn how to use a barometer to understand air pressure and predict actual weather changes.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

This activity was designed for blind learners, but all types of learners can use it to design and build a catapult that will toss a marshmallow or pompom over a distance of at least 12 inches, using the appropriate materials and tools safely.
