Science and Technology

Curriculum Overview

Science is a way of knowing which seeks to describe and explain the natural and physical world. An important part in building scientific and technological literacy is an understanding of the nature of science, which includes an understanding of the following: what scientists, engineers, and technologists do as individuals and as a community, how scientific knowledge is generated and validated. Science addresses what benefits, costs, and risks are involved in using this knowledge and how science interacts with technology, society, and the environment.  

The goals of the science and technology program is to relate science and technology to society and the environment. Science and technology is a subject in which students learn to consider both the knowledge and skills that will help them to understand and consider critically the impact of developments in science and technology on modern society and the environment.  

The science and technology curriculum is divided into four strands:

  • Understanding Life Systems: Growth and Changes in Plants 
  • Understanding Structures and Mechanisms: Strong and Stable Structures
  • Understanding Matter and Energy: Forces Causing Movement
  • Understanding Earth and Space Systems: Soils in the Environment

Complete the suggested activities using these resources and other TVO resources.

 

Suggested Activities

Complete these activities 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.
