What's under the microscope?

Background

Cells are the basic unit of living things and have specialised structures and functions. Most cells cannot be seen with the naked eye. Therefore, microscopes are used to study cells.

A stereo microscope is primarily used for viewing relatively large and solid specimens. They have a low magnification power and use two separate eyepieces with two objectives, which provides a three-dimensional image.

A compound microscope uses two sets of lenses to obtain a higher magnification than a stereo microscope. They are used to view small samples that cannot be identified with the naked eye. These samples are usually placed on a slide under the microscope. A compound microscope provides a two-dimensional image.


Key Learning Question

How is cell structure related to its function?


Prior Knowledge

Prior knowledge about cell organelles is preferred.


Learning Intentions

In this program students will:

  • Understand the different techniques used to prepare slides
  • Understand the difference between unicellular and multicellular cell structure & function

Activities

The students will:

  • Use a compound and a stereo microscope to examine the transport system in plants, by observing prepared slides and making wet mount slides.
  • Prepare a wet mount slide of Elodea, and use a compound microscope to investigate cell structure and function.
  • Study unicellular wetland organisms using compound microscopes, by preparing wet mount slides and using stains to concentrate on their different methods of locomotion.

Victorian Curriculum

  • Cells are the basic units of living things and have specialised structures and functions (VCSSU092)
  • Multicellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce (VCSSU094)

Learning Continuum

The following Learning Continuum is a guide for teachers to show the links between the programs Ecolinc offers onsite, online and through outreach. The Learning Continuum can be used to access Ecolinc resources to support the development of units of work.

Ecolinc Learn Online is an online learning management system offering interactive online courses for students and teachers. These courses can be undertaken either as a pre-visit, post-visit or stand-alone. Students are encouraged to do the pre-learning course before coming to Ecolinc for an onsite program.

Outreach programs are conducted by an Ecolinc education officer at your school. They are available to moderately disadvantaged primary schools in the Geelong, Ballarat and western suburbs areas (or within 100km radius from Bacchus Marsh)
