Audience
7th Grade Students
Time Frame
One full 5 day week is required to complete the progression of the unit.
Activity: Day 1 Bacteria Research
Day 2 Macrofluidic and Microfluidic devices
Day 3 Introduction to Research Microfluidic Devices and Microscopes
Day 4 Preparation of Microfluidic Device microscope slides
Day 5 Observation of chemotaxis of cells and Bacteria on Plates of Agar
Objective(s)
After completing the activity, participants will be able to:
- Have a deeper knowledge of what bacteria are.
- Understand why bacteria are important for humans to study.
- Understand how scientists study bacteria.
Next Generation Science Standards Addressed:
MS – LS1-1 Conduct and investigation to provide evidence that living things are made of cells; either one cell or many different types of cells.
MS – ETS1-2 Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Engineering principles
ETS2.A: Interdependence of Science, Engineering, and Technology
On Day 2 of the project students will be asked to use, observe, and describe the use of microfluidic and microfluidic devices.
They must analyze the design of macrofluidic and microfluidic devices, observe liquids within each type of device, and report on how the devices work. Students are also asked to collaborate to infer differences between behavior of liquids within a macrofluidic device and a microfluidic device.
Activity Materials and Activity Instructions

Assessment
I used the Bacteria Frayer Model and the Bacteria Anticipation Guide as assessments for this project. Both are located on page 3 of the Microfluidics Device and the Study of Bacteria Document.
Background
This unit was created with the understanding that seventh grade students probably have very little background knowledge concerning bacteria and the use of microfluidic devices.
Supplemental Materials

- Microfluidic Devices and the study of Bacteria
- ActiveInspire Flipchart slide show document used for display of visuals on Promethean Board.
