A criminal case has just been opened. Your task is to help close it.
Have you ever wondered how forensic science works? You may have seen police and crime lab work on television but what is a real forensic science investigation like?
This site includes information and activities that recreate some of the challenges forensics experts deal with. You will learn first-hand about forensics by taking on the roles of Forensic Archaeologists, Anthropologists, Entomologists, Botanists, DNA Analysts, and Stable Isotope Analysts. Each of your tasks will be a real job that a forensic expert does and every step is important to solving the case. Think carefully, but if you get stuck there are hints to help you.
Additionally, there are expert videos on each discipline, photographs of practising forensic scientists at work in the field and in the lab, and a detailed textual library in the "Resources" section. Links to these resources occur at the end of each activity.

In this unit, students explore a variety of resources—texts, images, sounds, photos, and other artifacts—to learn more about the Holocaust. Beginning with journal writings and a picture book to introduce the central issues, the unit focuses on student-centered inquiry. Students explore a range of print and non-print resources through extensive online inquiry activities. Progressing from individual work to a group learning project, the unit culminates in publishing the group's findings in topic-based newspapers.

The lesson includes complete lists of picture books, read-aloud books, reference texts, and online sites and collections that allow teachers to customize the activities to fit the available resources and students' specific research interests.

Students explore a variety of resources as they learn about the Holocaust. Working collaboratively, they investigate the materials, prepare oral responses, and produce a topic-based newspaper to complete their research.

Students learn about radar imaging and its various military and civilian applications that include recognition and detection of human-made targets, and the monitoring of space, deforestation and oil spills. They learn how the concepts of similarity and scaling are used in radar imaging to create three-dimensional models of various targets. Students apply the critical attributes of similar figures to create scale models of a radar imaging scenario using infrared range sensors (to emulate radar functions) and toy airplanes (to emulate targets). They use technology tools to measure angles and distances, and relate the concept of similar figures to real-world applications.

"Provided below are links to a series of free booklets to assist mathematics teachers of Grades 4, 5, 6.

These books will stimulate interest, competence, and pleasure in mathematics among students. The activities are appropriate for either individual or group work. Collaborative activities allow students to construct their own meanings and understanding. This emphasis, plus the "Extensions'' and related activities included with individual activities/projects, provide ample scope for all students' interests and ability levels. Related "Family Activities'' can be used to involve the students' parents/caregivers.

Each book is intended to occupy about one week of daily classes. However, teachers may choose to take extra time to explore the activities and extensions in more depth. The books have been designed for specific grades, but need not be so restricted. Activities are related to curriculum expectations."

By observing the slicing of an apple, students become aware of the small fraction of the Earth’s limited land that is used to produce food.

In which John Green teaches you about Iran's Revolutions. Yes, revolutions plural. What was the1979 Iranian Revolution about? It turns out, Iran has a pretty long history of unrest in order to put power in the hands of the people, and the most recent revolution in 1979 was, at least at first, not necessarily about creating an Islamic state. It certainly turned out to be about that, but it was initially just about people who wanted to get rid of an oppressive regime. Listen up as John teaches you about Iran's long history of revolution.

This is a lesson to demonstrate magnetic field lines in 2- and 3-dimensions. In the first activity, learners sprinkle iron filings over a magnet underneath a paper and record their observations. The second activity involves building a 3-D magnetic field visualizer using a clear plastic bottle, a cow magnet and iron filings. This is the second lesson in the first session of the "Exploring Magnetism" teacher guide.

In this activity, students graph second and third order functions, discovering an inverse relationship between squares and square roots and between cubes and cube roots. Students graph these functions on both linear grid (evenly spaced numbers), and a log-log grid (evenly space exponents). Graph lines that curve on linear grids transform into straight lines on the log-log grids, with slopes equal to their exponential powers. This activity is activity E3 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

When students plot irrational numbers on the number line, it helps reinforce the idea that they fit into a number system that includes the more familiar integer and rational numbers.

An interactive applet and associated web page that show the behavior of irregular polygons. The applet shows initially an irregular convex polygon. All vertices are draggable and when dragged show that this has no effect on any other vertex. The polygon can be made regular, and the number of sides changed between 3 and 99. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This site offers instructional activities for irregular and high frequency words. Not all words use the most common phoneme-grapheme correspondences, but most words are at least partially decodable. Many words appear so frequently in text that children need to learn them before they have been taught the necessary phoneme-grapheme correspondences. The resources on this site provide a range of options for you to teach such words.

This is lesson 4 of 4. Students will be presenting and evaluating their apps for cell phones that will provide farmers with the opportunity to learn how different irrigation methods work depending on soil type.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

In this activity, students conduct an investigation to purify water. They engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment. Through this activity and its associated lesson, student teams follow the steps of the engineering design process related to water treatment, as done by practicing engineers, including constructing and testing their designs.

To better understand electricity, students investigate the properties of materials based on their ability to dispel static electricity. They complete a lab worksheet, collect experimental data, and draw conclusions based on their observations and understanding of electricity. The activity provides hands-on learning experience to safely explore the concept of static electricity, learning what static electricity is and which materials best hold static charge. Students learn to identify materials that hold static charge as insulators and materials that dispel charge as conductors. The class applies the results from their material tests to real-world engineering by identifying the best of the given materials for moving current in a solar panel.
