Some changes may be made at the grantee's discretion as long as they are within the limits established by NIH. In other cases, NIH prior written approval may be required before a grantee makes certain budget modifications or undertakes particular activities. The grantee-initiated changes that may be made under the grantee's authority and the changes that require NIH approval are outlined below and, with respect to particular types of awards, activities, or recipients, in Subpart IIB. In addition, individual awards may restrict grantees' authorities to make budget and project changes without NIH prior approval.
What are the characteristics of Drosophila melanagaster fruit Flies? How long is the life and reproductive cycles of Drosophila?
How does one feed and maintain these fruit flies? Has ultra violet light been used to produce mutations in other organisms and what were the results?
What kinds of research have been conducted on mutations in fruit flies and what were the results? A control is the variable that is not changed in the experiment. What purpose does a control serve? It is used to make comparisons as to what changed or possibly caused the change.
Variables are factors that can be changed in an experiment.
What is an independent variable? The independent variable is the one that is changed in the experiment. What is a dependent variable? The dependent variable is the one that changes as a result of the change in the independent variable.
Experimental Procedure State the problem you are going to investigate in this science fair project. Create the data sheets you will use to record your observations. Purchase and gather all your materials.
Prepare the banana medium to feed the fruit flies. Dissolve 15g of agar in ml of water and bring to a boil. With a fork, mash a banana or push the banana through a strainer. Measure out g of the banana pulp and adds it to the agar.
Pour this mixture into the bottles. Cut small pieces of toweling into strips and place two strips into each bottle. Now cover the bottles and tilt them to increase the surface area for the flies. When the mixture has set, open the bottles and insert the flies, cover each bottle with a thin layer of gauze.
At the end of two weeks, repeat this procedure and transfer the flies into the new bottles.
Use the camel hair brush to transfer them. With the magnifying glass, examine the fruit flies and record their prominent characteristics such as body color, gray or black, eye color red or pink, wing type long wings, vestigial wings and the sexes. You may wish to make labeled sketches of some of these flies in the before and then later, in the after stage.
Anmrrange with your dentist or neighborhood chemist to have one bottle of flies irradiated with ultraviolet light. Use the lowest nanometer rating, Angstrom units for 30 seconds.The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue.
