In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

Students see how potential energy (stored energy) can be converted into kinetic energy (motion). Acting as if they were engineers designing vehicles, they use rubber bands, pencils and spools to explore how elastic potential energy from twisted rubber bands can roll the spools. They brainstorm, prototype, modify, test and redesign variations to the basic spool racer design in order to meet different design criteria, ultimately facing off in a race competition. These simple-to-make devices store potential energy in twisted rubber bands and then convert the potential energy to kinetic energy upon release.

The purpose of this task is to present students with a context that can naturally be represented with an inequality and to explore the relationship between the context and the mathematical representation of that context; thus, this is an intended as an instructional task.

This thematic unit from Comox Valley Schools (SD71) in B.C. is aimed at Grade 6 Core French students, but is suitable for older grades and would be easily adaptable for younger ones. It is focused on oral practice and participation and would also be useful in French Immersion classes!Content Authors: Comox Valley Schools, Learn71, Beth Peddle

Spotlight on Careers is an opportunity for secondary students to explore potential future career paths. Participants in a Spotlight are exposed to post-secondary opportunities, hands-on experiences, and mentorship from professionals in a specific industry.

This lab demonstrates Hooke's Law with the use of springs and masses. Students attempt to determine the proportionality constant, or k-value, for a spring. They do this by calculating the change in length of the spring as different masses are added to it. The concept of a spring's elastic limit is also introduced, and the students test to makes sure the spring's elastic limit has not been reached during their lab tests. After compiling their data, they attempt to find an average value of the spring's k-value by measuring the slopes between each of their data points. Then they apply what they've learned about springs to how engineers might use that knowledge in the design of a toy that enables kids to jump 2-3 feet in the air.

This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.

This short video and interactive assessment activity is designed to teach third graders an overview of area and perimeter.

Through hands-on group projects, students learn about the force of compression and how it acts on structural components. Using everyday materials, such as paper, toothpicks and tape, they construct structures designed to (hopefully) support the weight of a cinder block for 30 seconds.

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a scaled drawing of the pyramid using graph paper.

One way of thinking about family life says that there are stages that families move through: courtship, marriage, child-rearing, and family life in your later years. We’ll also discuss changing patterns of marriage and childbearing in the US, highlighting some of the varied family types that exist.

This task uses language, "half of the stamps," that students in Grade 5 will come to associate with multiplication by the fraction 12. In Grade 3, many students will understand half of 120 to mean the number obtained by dividing 120 by 2. For students who are unfamiliar with this language the task provides a preparation for the later understanding that a fraction of a quantity is that fraction times the quantity.

This art history video discussion examines the "Standard of Ur", c. 2600-2400 B.C.E. (British Museum).

The Stapleless Book can be used for taking notes while reading, making picture books, collecting facts, or creating vocabulary booklets . . . the possibilities are endless!

This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet ‰ÛÏSnorkzat‰Û� has an atmosphere. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.
