Through this unit, students act as engineers who are given the challenge to design laparoscopic surgical tools. After learning about human anatomy and physiology of the abdominopelvic cavity, especially as it applies to laparoscopic surgery, students learn about the mechanics of elastic solids, which is the most basic level of material behavior. Then, they explore the world of fluids and learn how fluids react to forces. Next, they combine their understanding of the mechanics of solids and fluids to understand viscoelastic materials, such as those found in the human body. Finally, they learn about tissue mechanics, including how collagen, elastin and proteoglycans give body tissues their unique characteristics. In the culminating hands-on activity, student teams design their own prototypes of laparoscopic surgical robots remotely controlled, camera-toting devices that must fit through small incisions, inspect organs and tissue for disease, obtain biopsies, and monitor via ongoing wireless image-taking. They use a (homemade) synthetic abdominal cavity simulator to test and iterate the prototype devices.

In this activity, students use a piano keyboard to model spectral lines as musical chords. It is designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars. Traditionally, spectral images are two dimensional, and related to text. This auditory activity allows students to "hear" differences in patterns of various elements (e.g., nickel or helium). This activity is part of the "What is Your Cosmic Connection to the Elements" information and activity booklet. The booklet includes photos, teachers notes and instructions, and a link to a color image pdf of visible light spectra that can be printed and used to do the activity. This activity requires a piano keyboard, color printout or construction paper and/or toothpicks (to mark spectral lines of elements).

Normally we find things using landmark navigation. When you move to a new place, it may take you awhile to explore the new streets and buildings, but eventually you recognize enough landmarks and remember where they are in relation to each other. However, another accurate method for locating places and things is using grids and coordinates. In this activity, students will come up with their own system of a grid and coordinates for their classroom and understand why it is important to have one common method of map-making.

In this activity, students view a satellite image of Earth at night, and consider the environmental considerations and consequences associated with the pattern of light they see. The resource includes a map for student use. Summary background information, data and images supporting the activity are available on the Earth Update data site. To complete the activity, students will need to access the Space Update multimedia collection, which is available for download and purchase for use in the classroom.

In this activity students develop a simplified log table using information from their Log Tapes. Then they use it to solve arithmetic problems by looking up and combining logs, and finding the antilog. Because these problems are extremely simple, students appreciate the logic of logarithms without getting bogged down in the arithmetic detail and error.åÊThis is activity B3 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.

Acting as biomedical engineers, students design, build, test and redesign prototype heart valves using materials such as waterproof tape, plastic tubing, flexible plastic and foam sheets, clay, wire and pipe cleaners. They test them with flowing water, representing blood moving through the heart. As students creatively practice engineering problem solving, they demonstrate their understanding of how one-way heart valves work.

Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. In an associated literacy activity, students learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp.

So, what happens to normal stuff (like water) when it goes to not so normal places? What happens if you take a glass of water to the top of Mt. Everest? Or Space? In this episode of Crash Course Kids, Sabrina shows us how matter is affected by different pressures and how that make water do some weird things.

North American Association for Outdoor Education offers a rich bank of resources to get students to interact with nature through art and science exploration. There are many cross-curricular activities that can be done in students’ backyards. Some resources include printable material, while others have links to videos and detailed activity guides. While this resource is North American, rather than specific to Canada or Saskatchewan, many of the activities align with Saskatchewan Curriculum.
Each age level find: - Resource Guides, Lesson Plans, and Teaching Activities - Interactive Websites - Apps - Podcasts & Videos

The provision of northern health care entails many unique challenges and circumstances that are rarely represented in mainstream health sciences education. This OpenEd Resource provides accessible content on health and health care from a northern perspective for the growing number of health professionals being educated in northern communities.

Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. In accompanying activities, they explore how ground-based tracking and onboard measurements are performed. Also provided is an overview of orbits and spacecraft trajectories from Earth to other planets, and how spacecraft are tracked from the ground using the Deep Space Network (DSN). DSN measurements are the primary means for navigating unmanned vehicles in space. Onboard spacecraft instruments might include optical sensors and an inertial measurement unit (IMU).

Students are introduced to acids and bases, and the environmental problem of acid rain. They explore ways to use indicators to distinguish between acids and bases. Students also conduct a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment, as well as how engineers address acid rain. In an associated literacy activity, students learn how persuasive techniques are used to develop an argument, and create an environmental case study.

"Le changement climatique et la perte de biodiversité peuvent avoir de nombreuses répercussions sur la santé humaine. Nous avons déjà appris comment la pollution, l'augmentation des températures et les changements dans la qualité de l'air et de l'eau peuvent affecter notre santé.
Le changement climatique peut entraîner des conditions météorologiques extrêmes et des catastrophes naturelles telles que des inondations ou des sécheresses. Ces conditions font qu'il est difficile pour les gens d'accéder à de l'eau potable, de cultiver de la nourriture et de rester chez eux. Il est difficile de rester en bonne santé si vous n'avez pas assez de nourriture et d'eau potable ou si vous êtes déplacé de chez vous."
