Science Skills-2

Card sort for level 3-4 Science Skills Lesson 2.

Source 1: For each crop, individual fields were divided into two with the GM crop grown in one half and the non GM in the other. To gauge the effect on wildlife, scientists monitored weeds and weed seeds, and collected beetles and other insects in traps. Information about how study was done.
Source 1: Oilseed rape: Weeds were 1.7 times as plentiful in the conventional plots and produced five times as many seeds. A quarter fewer butterflies were recorded around the GM plots. Data and evidence
Source 1: Sugar beet: About 1.3 times as many weeds grew in conventional plots, and treble the number of seeds. There were 40 per cent fewer butterflies. Data and evidence
Source 1: Maize: The situation was totally reversed. There were three times as many weeds in the GM plots, and 2.3 times as much seed produced. Data and evidence.
Source 1: Geoff Squire, a trials coordinator, said that if the crops had been grown for the past 10 years, the oilseed rape and the sugar beet would have triggered further declines in wildlife, but the maize would have increased biodiversity on farms. Conclusion based on results.
Source 1: The organisers believe the four-year "farm scale evaluations" have been a resounding success. "It's the first time a novel agricultural technology has been trialled extensively before it's been introduced, rather than after," Opinions and ideas
Source 2: The results come from two years of trials that compared aphid attacks on standard wheat plants with those suffered by a GM version modified to release a natural aphid repellant. . Information about how study was done.
Source 2: Helen Wallace at the campaigning group, GeneWatch, argued that the field study was a waste of taxpayer’s money. “With GM crops, it’s always jam tomorrow and never jam today,” she said. Opinions and ideas.
Source 2: “The disappointing thing is that when we tested it in the field, we didn’t find any significant reduction in aphid settlement in the test plots,” said Toby Bruce, who worked on the trial. . Data and evidence.
Source 2: “Our major conclusion was that this strategy doesn’t work in nature because the aphids get used to the continuous release of their alarm pheromone and thus learn to ignore it. ” he said. . Conclusion based on results.
Source 3: Recent field trials are showing an average of 2 bushels per acre increase in yield as compared to untreated crops. . Data and evidence.
Source 3: As a high-oleic soya bean product, Vistive Gold also brings the potential for new opportunities in industrial use and applications to replace comparable oils in industrial lubricants. Opinions and ideas.
Source 4: The review in question is a meta-analysis. This is a statistically rigorous study of studies, rather than a mere summary of the literature. . Information about how study was done.
Source 4: With both forms of modification, however, the yield rise was so great (9% above non-GM crops for herbicide tolerance and 25% above for insect resistance) that farmers who adopted GM crops made 69% higher profits than those who did not. . Data and evidence.
Source 4: Many poor countries eschew GM crops, fearing they will not able to export them to areas which ban them, notably the European Union. . Opinions and ideas.
Source 4: Farmers in developing nations who use the technology achieve yields 14 percentage points above those of GM farmers in the rich world. Pests and weeds are a bigger problem in poor countries, so GM confers bigger benefits. . Conclusion based on results.
Source 5: According to the report, corn was selected from two adjacent fields one growing GM corn and the other growing non-GMO corn. The corn ears were selected from multiple locations in each field two weeks prior to harvest to get a proper sampling Information about how study was done.
Source 5: Shattering the myth that there's no substantial difference between GMO and non-GMO crops, the report by De Dell Seed Company of London, Ontario, shows that GMO corn is nutritionally deficient and wholly unfit for human consumption. . Opinions and ideas.
Source 5: When the results came back, researchers found that the Roundup Ready corn contained 13 parts per million (ppm) of glyphosate, the primary active ingredient in Monsanto's Roundup herbicide. Data and evidence.
