After reading the electronic version of the Jumanji book, please take this quiz to test your knowledge and understanding.
Elementary Mathematics: Times Tables II
Learn and practice times tables. This is the second of two modules and practices the 6, 7, 8, 9, 11 and 12 times tables. It includes multiplication testing, corresponding division exercises and missing-operand exercises as part of a range of different task types designed to develop an all-round understanding of the times tables.
Enhancing Physics Knowledge for Teaching – Maxwell’s Equations
In this session we’re going to look at how electricity and magnetism can be unified into a system of equations, named after James Clerk Maxwell, the Scottish physicist who first proposed them. Then we’ll see how this leads to an understanding of the nature of electromagnetic radiation.
Berkeley Writers at Work: Michael Pollan
Pollan reads from his work, is interviewed about his writing process, and answers questions from the audience. Michael Pollan is Knight Professor of Journalism at the Graduate School and director of the Knight Program in Science and Environmental Journalism. He is a contributing writer at the "New York Times Magazine", and the author of three books: "The Botany of Desire: A Plant's-Eye View of the World"; "A Place of My Own"; and "Second Nature". For many years he served as Executive Editor of
The Chicken or the Egg: Agency and Autonomy in Informed Consent
One of the fastest growing global markets is pharmaceutical sales. With changing political landscapes and an increased awareness of new customers worldwide, sales have increased in Eastern Europe, Asia, and especially Latin America. As researches expand into countries with poor socio-economic and political infrastructures, guidelines such as the Helsinki Declaration, the Nuremburg Code, and the Belmot principles are being challenged. Regulatory and ethical guidelines have not
Rocking the Boat
The concepts of stability and equilibrium are introduced while students learn how these ideas are related to the concept of center of mass. They gain further understanding when they see, first-hand, how equilibrium is closely related to an object's center of mass. In an associated literacy activity, students learn about motion capture technology, the importance of center of gravity in animation and how use the concept of center of gravity in writing an action scene.
Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household appliances and toys. In the associated activities, students learn how a circuit works and test materials to see if they conduct electricity. Building upon a general understanding of electrical energy, they design their own potato power experiment. In two literacy
Go with the Flow
Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.
Will It Fly?
In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.
In this activity, students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.
Pitch and Frequency
To further their understanding of sound energy, students identify the different pitches and frequencies created by a vibrating ruler and a straw kazoo. They create high- and low-pitch sound waves.
Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theaters
Students learn how a bill becomes law in the U.S. Congress and research legislation related to global warming.
The Disaster Dynamics project is a learning environment for the study of the unique challenges surrounding natural disasters. By focusing on dynamics, this project emphasizes the complex and emergent interplay between different aspects of the design activities and the extreme event. The website has several educational role-playing simulation games such as decision making under uncertainty, complex systems and emergent properties, understanding design decisions and fostering collaborations.
Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ
This exercise opens up discussion on global biodiversity loss. Students count the number of species they can find in a five-minute block of time in both an urban green space and natural, unmanaged forest area. They will begin to recognize low and high biodiversity areas and understand what affects biodiversity loss. This exercise can be completed in one normal two-hour lab session. This SERC Starting Point site includes learning goals, context for use, teaching tips, assessment, and references.
Diversidad Cultural en Chile : ¿Utopía o Realidad?
Hoy en día estamos viviendo un proceso de promoción de la diversidad cultural en todo el mundo, tendencia generada en parte como respuesta a la vocación homogeneizadora de ese ente multiforme que llamamos globalización. La sociedad chilena no es ajena a este diálogo, que abarca desde lo cultural, hasta lo económico, pasando por lo social, lo político, etc. El curso ‘Diversidad cultural en Chile y el mundo: ¿utopía o realidad?&
Star Library: What Makes the Standard Deviation Larger or Smaller?
The activity is designed to help students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability. As they learn about the standard deviation, many students focus on the variability of bar heights in a histogram when asked to compare the variability of two distributions. For these students, variability refers to the “variation” in bar heights. Other students may focus only on the range of
Java Demography, an application that simulates exponential growth in age-structured populations, enables users to manipulate values for age-specific mortality rates, fertility rates, and initial population characteristics. Through observation of how population characteristics change through time, users of Java Demography can investigate important questions in population biology, develop a deeper understanding of fundamental population concepts, and explore issues related to population policy.
Data Analysis: Two-Dice Toss
Once students realize that the outcomes of tossing one die are equally likely, they sometimes transfer that knowledge to tossing two dice. This is a common misconception that is best addressed through data collection and analyzing that data rather than through telling. See suggested two-dice games below that students can play to gain experiential knowledge of the results of tossing two dice. Several of the games encourage students to develop better strategies in order to win and their growing un
