Within the following topic subdivisions you will find extra ideas and activities to help students meet the objectives in Alberta's Information and Communication Technology curriculum.

The following Technology Ideas are divided into the three major concepts you will find in the Energy and Matter in Chemical Change unit. Click below to jump to a particular topic, or simply scroll down this page.

• 1.0: The understanding that particles make up the underlying structure of matter has led to advancements in technology
• 2.0: Elements combine to form many substances, each with its own set of properties
• 3.0: Chemical change is a process that involves recombining atoms and energy flows
