Students observe how water acts differently when placed on hydrophilic and hydrophobic surfaces. They determine which coatings are best to cause surfaces to shed water quickly or reduce the "fogging" caused by condensation.

Dominoes have become a staple in most primary classrooms. They build upon dice patterns and are often used to model decomposition of numbers, building student knowledge of addition facts. They are an excellent manipulative for primary students to use and these are some examples of how students might use dominoes in the math center. Try these domino games with students to improve math skills and number recognition. Encourage students to play these games at home with their families, using real dominoes or paper copies.

Students will investigate different types of renewable and nonrenewable energy as they evaluating competing claims about humans' sources of power.

Forensic anthropology is the application of anthropology to criminal investigations. It incorporates concepts and methods from biological anthropology (the study of the physical aspects of humanity).
Identifying unknown individuals is a key part of forensic anthropology. Anthropologists assist in identifications primarily by constructing a biological profile. This includes estimating age, sex, stature, and ancestry, as well as identifying specific characteristics, like diseases or injuries. In addition to helping identify human remains, the anthropologist analyzes injuries that happened around the time of a person's death, which can help determine how a person died. To do these things, an anthropologist begins by asking a series of important questions.

Website includes more information on forensic anthropology, including photos and videos.

Students increase their media literacy skills by critically examining and revising junk mail.

This lesson focuses on torsion as a force acting upon structures. Students will have the opportunity to design something to withstand this force.

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.
