På måndagen handlade Klartext om att upprorsmännen i Libyen har tagit över flera städer. Dessutom hade vi med en 12-årig pojke som berättade om när han blev biten av en björn.

Using NBA Statistics for Box-and-Whisker Plots
In this lesson, students use information from NBA statistics to make and compare box-and-whisker plots. After reviewing the concepts of minimum, maximum, median, upper quartile and lower quartile, students create three box-and-whisker plots for sets of data on the heights and weights of basketball players. In each case, the students consider the effects of changing one piece of the data, such as eliminating the height of the tallest player. Detailed instructions for the lesson, assessment option
Every Breath You Take
In an activity designed to help students develop number sense, each student estimates the number of times s/he breathes in one hour, and the class graphs the estimates, finds the mean and median of the estimates, and discusses outliers. Students then brainstorm how they could find out how many breaths a person actually takes in a day—and implement their strategies.
Accessing and Investigating Population Data
In this activity, students investigate population projections from 1990-2100 using data from the U.S. Census Bureau Web. Using the five specific population pyramids, students investigate population projection data for the United States over a 110-year period. They examine how the population data is distributed over time and explain what factors might contribute to these trends. An activity sheet and thoughtful questions, included in the lesson plan, guide the class investigation.
Problem solving is the thought processes involved in solving a problem. It is both a means of developing students' knowledge of mathematics and a critical outcome of a good mathematics education. A mathematical problem, as distinct from an exercise, requires the solver to search for a method for solving the problem rather than following a set procedure. Mathematical problem solving, therefore, requires an understanding of relevant concepts, procedures, and strategies. To become good problem solv
Students are given the timetables of two trains, each going along the same route, but one coming and the other going. Carefully crafted questions ask students to create and analyze a graph of position vs. time for one train, then to explain mathematically the ways a graph of the other train’s run should resemble the first graph. Finally, they create the second graph and try to explain the unexpected discrepancies between the two graphs. A full solution and scoring rubric are included.
A Whole-School "Read" Creates a Reading Community
A whole-school read solved a potentially disruptive problem by providing a common reading experience that addressed student diversity through a school-wide, interdisciplinary, year-long event at Hand Middle School.
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. This online resource guide focuses on earth/physical science including volcanic island formation and tsunamis; life science concepts including ocean ecosystems, food webs, and biodiversity; science in personal and social perspectives including pollution
Mathematics as Communication
This grades 6-8 activity focuses on interpreting and creating graphs that are functions of time. Two activity sheets focus on graphs of time vs speed; two others look at how many times an event occurred in a specific amount of time. Inventing stories to correspond to the graphs is challenging but fun!
Exploring the Mysteries of the Ocean Floor
This article explains why scientists study the ocean floor; scientists travel to the seafloor to learn how deep sea organisms use the sun-less chemical environment to thrive.
Reading Comprehension Strategies
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. Do your middle school students not complete reading assignments or not comprehend them when they do? Is student motivation an issue you struggle with? Do you feel that your students need assistance comprehending the textbook? Students are faced with inc
International Boiling Point Project
The purpose of this project is to discover which factor in the experiment (room temperature, elevation, volume of water, or heating device) has the greatest influence on boiling point. Anyone can participate in this year's project. All you have to do is boil a bit of water, record a bit of information, and send it along to the website to have your results included in the database of results. Then, students can analyze all of the data to reach an answer to the question: What causes a pot of water
Human Genetics Project
Participants in this project will survey phenotypic traits of classmates and schoolmates, compile data with students from around the world, and analyze data to determine if the prevalent phenotype is the dominant allele. The Human Genetics Project is an Internet-based project which enrichs a student's learning experience through "Unique and Compelling" applications of instructional technology. In particular, this project taps into some of the exciting applications of the Internet in education by
A set of 26 videos showing brief lessons or mini-tutorials on algebra topics. These 2 to 19-minute lessons are appropriate for a first year algebra class. In each video, a teacher uses the blackboard to give clear, concise explanations of such elementary topics as slope, equations, and factoring, but also higher level topics such as conic sections and systems of equations.
Video Games in the Middle School Classroom
Video games use problem-based learning to engage and motivate students. They have the potential to meet curricular standards and challenge students to exceed those curricular standards.,Volume 39, Number 4
The purpose of this activity, designing a survey, is “to demonstrate how the results of a poll or other scientific study can be biased by selecting special types of people to respond or by asking only certain questions.” In this well-constructed lesson, students gather opinions on how much homework time is appropriate for them to have. Who should they interview? What questions should they ask? The task culminates in a persuasive, hopefully unbiased, report to the school principal.
Adapting Literacy Strategies to Improve Student Performance on Constructed-Response Items
This practical article discusses ways of adapting various reading strategies to help students improve their answers to extended-response questions on the mathematics portion of high stakes tests. Although initially addressed to Ohio educators, it is ultimately directed to all math teachers.
Parkinson Disease - Reflexes Exam - Superficial Sub-exam - Patient 4
This 76-year-old man developed tremor of his right arm and leg 15 years ago. It has increased in severity over the years. A shaking right hand affects his writing, dressing and drinking. Occasional drooling, difficulty rolling over in bed and a soft voice at times are also issues. The tremor has affected his writing and he has mild difficulty with buttons and zippers. He spills when he uses his right hand to drink. He has occasional drooling and slight difficulty rolling over in bed. His voice
Down the Drain: How Much Water Do You Use?
This Internet-based collaborative project will allow students to share information about water usage with other students from around the country and the world. Based on data collected by their household members and their classmates, students will determine the average amount of water used by one person in a day. They will compare this to the average amount of water used per person per day in other parts of the world. Students will record water use by members in their household for one week. At t
