Objective(s)
Students will:
- identify the Principles of
inoculating and handling sterile culture medium
- identify the Properties of
microbes such as fungi and bacteria
- use a microscope to examine growth of
cultures
- use a digital camera to document outcomes
- follow all laboratory safety procedures
when handling microbes
- practice teamwork
- make predictions and draw conclusions
- prepare a PowerPoint presentation for
peers
- perform peer evaluations
Time Required
One 90-minute class or block schedule or two
45-minute regular class periods
21st Century Tools (Technology Tools)
- Computer lab with Internet access
- PowerPoint software
- overhead projector
Procedure
- Remove agar plates from growth chamber
and evaluate agar plates for growth differences.
- Examine culture plates to compare growth
rates among various treatments (if appropriate for the grade
level, slides could be made and examined under a microscope)
- Use a digital camera to photograph and
document results
- Summarize results and include in
PowerPoint presentation
- Destroy inoculated media samples
according to school policy
- Develop summary of the results of laboratory
experiments on shopping carts, with photos, sketches, text
or tables to document the outcomes
- Conclusions about which treatments proved
effective and the costs of each type of treatment
- A summary of the selected engineering
area, describing the background education, college degree
required, the type(s) of work typically performed, and
conclusions about whether this field of engineering might
work on the problem of microbes on shopping cart handles.
- While presentations are being made,
students should complete peer assessment by completing the
assessment Rubric (printed out beforehand).
Author's Comments
Reserve the
computer lab; discuss the scope of the unit, assure it
focuses on engineers as problem-solvers, and allows teams to
tackle the problem of how to sanitize grocery cart handles that
transmit microbes; remind students to save their PowerPoint work
as they will be adding to it during ensuing lessons.
21st Century Assessment/Evaluation
Students will
generate a slide show presentation that will summarize their
findings and meet the requirements of the
rubric.
