How to Use These Resources

TVO Learn is designed to meet each student where they are on their learning journey. Learning Activities are comprehensive and require guided instruction from an adult, while Resources for Learning, Apply the Learning prompts and Vocabulary lists work well to reinforce specific skills or to enable independent exploration of a subject. Use these helpful tips to get the most from TVO Learn.

Curriculum Overview

Science is a way of knowing which seeks to describe and explain the natural and physical world. An important aspect is making connections between skills and concepts, and the practical applications of science and technology, and learning about life systems, matter and energy, structures and mechanisms, and Earth and space systems. Students develop important scientific literacy and technological skills that will enable them to thrive in today's rapidly changing world, their future professional and personal lives, and to become active problem solvers in their communities. As students engage in STEM education, the goals of the science and technology program is to apply scientific and engineering design processes to develop the sense of wonder about the world, to explore curiosity about what is observed, and to investigate problems relating to science, technology, society, and the environment.

The science and technology curriculum is divided into five strands:

  • STEM Skills and Connections
  • Life Systems: Growth and Changes in Plants 
  • Matter and Energy: Forces and Motion
  • Structures and Mechanisms: Strong and Stable Structures
  • Earth and Space Systems: Soils in the Environment

Apply the Learning

Choose from the following to consolidate learning across all curriculum strands.

  • Research how a plant spreads its seeds like the maple tree example in the “Spinning Seeds” video.
  • What are the major parts of plants? How does each part contribute to its survival?
  • Choose a variety of plants and observe and compare their parts.
  • Germinate seeds and record similarities and differences as seedlings develop.
  • Research a structure built by animals and compare it to a structure built by humans. Compare the materials and features of the structures. (For example, beaver dam, nests, anthill).
  • Design and build your own strong and stable structure that serves a purpose.
  • Design and build a device that uses forces for controlled movement.
  • What are some of the forces in nature and how can humans reduce or enhance their impact? (For example erosion, how do humans cause it and how can they prevent it?).
  • Create your own definitions for 20 of the words in the vocabulary list.
