For women of color‚ it is as if society was against them two times. As if being a woman is not already hard enough‚ don’t throw race into the picture as well! As this piece was viewed‚ my mind could hear “Strange Fruit” playing in the background. The struggle of living during such a depressing time is visible in the gaze of Miss Holiday. Ironically enough‚ since this painting as well as others in the gallery were of African American jazz musicians‚ I assumed that the artist themselves would also

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

LAB 3.Ø.Ø: do ions combine in definite ratios PURPOSE The purpose of this investigation is to determine whether ions combine in definite ratios or not. To observe‚ and create a table of the different ions. QUESTION If copper (II) sulfate when mixed with sodium carbonate at different quantities combine to form ions in definite ratios. HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any

Store‚ Fruit Ninja by Halfbrick. It was one of the number one apps in the App Store when it came out. Millions of people have been playing a true classic ever since the game launched in 2010. The game offers different options from which players can choose. This attracts players to explore all of the options the game has to offer. Fruit Ninja has been a family tradition for my cousins and me because we always try to break each other’s records. Although it has been about a decade since Fruit Ninja launched

Daniel Alohan Period 5/6 Mr. Cueter AP Biology Lab Report Investigation 12: Fruit Fly Behavior Abstract: In the lab that was conducted‚ students were supposed to examine the tendencies of fruit flies‚ specifically Drosophila’s‚ to move toward or away from important stimuli that aide in their survival‚ also known as taxis. Another objective for this lab was to identify the patterns and relationships between environmental factors and

I have taken it upon myself to help improve the amount of fruit that the vineyard produces. One area I noticed that could use improvement was the type of bird netting that was being applied. I personally picked the fruit and saw how much fruit was pierced by birds. I collected data by interviewing managers of the winery‚ and researching online about which practices produced the best outcome. This report analyzes our current bird netting and the procedures that go into it. I also recommend three

investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will be testing a range of different fruit juices to see which contains the highest
