Methods and Materials or Equipment can usually be a simple list, but make sure it is accurate and complete. Context for Use This activity can be completed at the beginning of the evolution unit when studying adaptations.
Students should put their data in data table in their lab book. Compare your results to similar investigations. Figure 1 Figure 2 Figure 3 On the other hand, when banana is absent, there are three normal flies at the food site for trial one, and there are two flies in trial two.
Next they will test a question. In this experiment, time was a liming factor, thus the observed time for each group of flies and trials were limited. Be sure to remind students a day ahead to where shoes with laces. Besides these factors, errors are a source of causing possible difference in data.
As for the vestigial flies, no flies entered the food site when banana is absent for the two trials.
Another factor that could change the result of this experiment could be the kind of fruit. It is important to follow the same procedure as done in step 1 so that data is consistent.
For best results, a partner can tape it to the pointer finger to render it useless. If there were differences, how can you account for them? Zero vestigial flies entered the food site after three minutes during trial one, and four for trial two.
Next they will test a question. Next, wait for two minutes, and then count how many vestigial flies have entered the food site during that time interval. The hypothesis of more flies with normal wings will be at the food site than the flies with vestigial wings was not supported by the data of this experiment.
What questions might we raise? What is the significance of the results? Teaching Notes and Tips Students should write down their procedure and data in their lab notebook instead of on handouts. Discuss as a class their ideas. The purpose of this experiment was to identify the specific element in a metal powder sample by determining its crystal structure and atomic radius.
When banana is absent, the number of flies with normal wings at the food site is distinctly higher than the number of flies with vestigial wings as explained by figure 3. Replicate this experiment for flies with normal wings. Students should understand the following vocabulary when finished: Since none of the samples reacted to the Silver foil test, therefore sulfide, if present at all, does not exceed a concentration of approximately 0.
The hypothesis of more flies with normal wings will be at the food site than the flies with vestigial wings was not supported by the data of this experiment.
Carefully transfer the vial full of flies with vestigial wings into the box, then tightly secure the vial in the hole on top of the box, make sure that there are not any flies getting out.An Experiment of Adaptation Introduction: Throughout history of time, organisms change in relation to their environment, consequently, adaptation is an essential property of life.
This experiment is designed to test the adaptation of Drosophila melanogaster.
This experiment is going to test the hypothesis that here will be more number of flies with normal wings at the food site than the number of vestigial wings. Not “Lab #4” but “Lab #4: Sample Analysis using the Debye-Sherrer Method”).
2. The Abstract summarizes four essential aspects of the report: the purpose of the experiment (sometimes expressed as the purpose of the report), key.

Experiment 1 Lab Report Essay Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2, I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions, a characteristic of many.
Activity: Bird Beak Adaptation Lab. Goal: To learn about the advantages and disadvantages of variations, by simulating birds with different types of beaks competing for various foods. Background Information: Darwin was amazed by the variation in the characteristics of plants and animals he encountered on his journey.
