Gait analysis is the study of human motion that can be utilized as biometric information or identification, for medical diagnostics or for comparative biomechanics. In this activity, students observe walking human subjects and then discuss parameters that could be used to characterize walking gaits. They use accelerometers to collect and graph acceleration vs. time data that can help in gait analysis—all part of practicing the engineering data analysis process. Students complete this activity before learning the material presented in the associated lesson.

The goal of this task is to get students to focus on the shape of the graph of the equation y=ex and how this changes depending on the sign of the exponent and on whether the exponential is in the numerator or denominator. It is also intended to develop familiarity, in the case of f and k, with the functions which are used in logistic growth models, further examined in ``Logistic Growth Model, Explicit Case'' and ``Logistic Growth Model, Abstract Verson.''

The goal of this task is to work on finding multiples of some whole numbers.

This task requires students to determine whether a number is rational or irrational. The task assumes that students are able to express a given repeating decimal as a fraction.

In this task, students use trigonometric functions to model the movement of a point around a wheel and, in the case of part (c), through space (F-TF.5). Students also interpret features of graphs in terms of the given real-world context (F-IF.4).

This is a direct task suitable for the early stages of learning about exponential functions. Students interpret the relevant parameters in terms of the real-world context and describe exponential growth.

In this role-playing activity, students learn how cellular phone service works, its advantages and its limitations. Students also learn about the advantages and limitations of satellite phone service. Phone communication involves many aspects of science, math and engineering, and this activity conveys to students how these technologies help people to stay better connected. Students use what they learn to understand what communication options might be available for Maya and her parents, Spacewoman Tess and Spaceman Rohan.

As stated in the United Nations Declaration on the Rights of Indigenous Peoples, and by numerous writers, activists, politicians, poets and Indigenous peoples themselves, a nation’s culture is central to its identity and viability. To understand how a culture can be affected by the presence of external forces, it’s important to understand the complexity of the word “culture.”

Students are asked to consider the expression that arises in physics as the combined resistance of two resistors in parallel. However, the context is not explicitly considered here. The task is good general preparation for problems more specifically aligned to either A-SSE.1 or A-SSE.2.

The purpose of this task is to help students see manipulation of expressions as an activity undertaken for a purpose.

For millennia, the Haíɫzaqv have depended on the seasonal cycles that bring ocean resources to the coast. Every generation learns to harvest in a sustainable way. But now these resources are dwindling. And it's up to us—all of us—to work together to put things back in balance. If you like this content you can see all of the available resources in the Harvest module in the Ocean School Help Centre (https://help.oceanschool.nfb.ca/educational-resources/module-guides/the-harvest-module-guide).

Balancing act "c̓isḷa" comic activity. Students learn more about c̓isḷa—the act of looking after and taking care of something important. Students then create a comic that illustrates people taking care of and giving back to nature.

>> About the Indigenous content
This content was filmed and developed on unceded Haíɫzaqv homelands and waterways in direct collaboration with members of the Haíɫzaqv Nation. The Haíɫzaqv are an Indigenous Nation living in (what is currently) Canada's province of British Columbia (http://www.heiltsuknation.ca/about-2/territory/). We are sincerely grateful to the Haíɫzaqv Nation for allowing Ocean School to be guests in their territory, for sharing their stories and knowledge, and for collaborating with us for this module. All Haíɫzaqv language use in Ocean School content is overseen by the Heiltsuk Integrated Resource Management Department (https://www.hirmd.ca/).

>> About Ocean School
Ocean School is a free educational resource from the Canadian Government about the ocean, through Dalhousie University, Ingenium - Canada’s Museums of Science and Innovation, and the National Film Board of Canada. Ocean School is inquiry-based, entirely online, available in English and French, and for students in grades 5-9. Learn more about the Ocean School project at our What is Ocean School page.

The purpose of this task is to probe students' ability to correlate symbolic statements about a function using function notation with a graph of the function, and to interpret their answers in terms of the quantities between which the function describes a relationship

About This Guide
These guides are designed by the Global Digital
Citizen Foundation to help you gain a better
understanding of the 21st Century Fluencies and
how they work.
This guide contains a description of the stages of
Information Fluency, as well as a perspective on the
skills each stage develops and why they are important
for our students?and everyone?to learn.
We hope this information will help you with the
development of the Fluencies as you work to infuse
them into your students' learning experiences.

This task shows how to inscribe a circle in a triangle using angle bisectors. A companion task, ``Inscribing a circle in a triangle II'' stresses the auxiliary remarkable fact that comes out of this task, namely that the three angle bisectors of triangle ABC all meet in the point O.

This task is primarily for instructive purposes but can be used for assessment as well. Parts (a) and (b) are good applications of geometric constructions using a compass and could be used for assessment purposes but the process is a bit long since there are six triangles which need to be constructed.

This task provides an opportunity for students to apply triangle congruence theorems in an explicit, interesting context.

This problem introduces the circumcenter of a triangle and shows how it can be used to inscribe the triangle in a circle. It also shows that there cannot be more than one circumcenter.

This task focuses on a remarkable fact which comes out of the construction of the inscribed circle in a triangle: the angle bisectors of the three angles of triangle ABC all meet in a point.

In this task students are asked to label negative numbers on a numberline and then answer questions about which are greater or less than.
