Occasionally you will find instructions in the Addison Wesley Science 10 textbook that direct you to the Internet for further instructions regarding technology activities. We've developed this Technology Ideas page so that you will always be able to reach safe, reliable resources on the World Wide Web.

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 Flow of Matter in Livings Systems unit. Click below to jump to a particular topic, or simply scroll down this page.

• 1.0: Our current understanding of the cell is due in part to developments in imaging technology
• 2.0: Living systems are dependent upon the functioning of cell structures and organelles
• 3.0: Plants are multicellular organisms with specialized structures

How a Microscope Works - the concept of magnifying with a lens, and building your own microscope will be much easier after this.

Text Pages 243-245
