Flies On Ice
Flies On Ice is an activity developed to introduce students to experimental design, animal models used in biomedical research and basic concepts in neuroscience.
Upon completion of the Micropipette Challenge Lab, students will be able to:
* Understand how to properly use a micropipette
* Read and follow a laboratory protocol
* Perform unit conversions, with an emphasis on microliters to milliliters
Students should have a basic understanding of a micropipette (what is it?). Don't worry, we will go over how to use it before jumping into the activity. Students should also have a general understanding of the metric system and the common metric units used for volumes. A review of the metric system and metric conversions can be found here:
Math is Fun
Roy, Gee, and Biv were asked by their teacher to create a spectrum, but they have no idea what to do and need your help! Using red, blue, and yellow solutions, you will make a visible spectrum, but in order to correctly do this, you will need to use a micropipette. Employing your knowledge of the metric system and unit conversions, you will learn how to operate a micropipette and measure small quantities of liquids to create your spectrum.
Students should be able to answer these questions before beginning the Micropipette Challenge. Also, refer to the Pre-Lab Activity above.
* What is the metric system?
* What is the SI system of measurement?
* What countries use the metric system? What system of measurement does the
United States use?
* What is a unit conversion? What is a conversion factor?
* How do you convert from milliliters to liters?
* Why do you think it is important that scientists use units in their work?
