Sam, Josh, Megan, Danielle, and Isaac are all studying an invasive plant along the Ankh-Morpork river basin and natural areas. This plant, the Venezuelan Salt berry, can grow into a tree up to 10 meters high with a total shade cover many times this height. When one stem is cut, many more will sprout beneath the cut line to produce a tangled web of new branches. The entire tree must be cut at soil level and treated with special herbicides to prevent regrowth. The berries are small, less than 7mm in diameter, and bright red when ripe. They tend to grow in large clusters at the terminal end of branches. Each of our young scientists are testing a different hypothesis to prove how the Venezuelan Salt berry is spreading so quickly along the muddy banks of the river and into the interior. Sam observed that the most abundant species of bird, a common lark, quite enjoys the berries and eats voraciously from the clusters throughout the summer months. Josh observed that when hiking through the wooded areas, there are many areas of bear scat that are red from the abundance of berries. Megan heard people say that bees make a mighty fine honey and local people have been planting them in orchards for their apiaries. Danielle read a newspaper article which mentioned the tree was brought over from the Rim as an ornamental plant which escaped a botanical garden. Isaac believes that wind carries the berries, after they ripen and dry out on branches, across great distances in the windy, dry season. Explain how Megan would approach her observation with the scientific method to determine if she was right in her thoughts. Be details, label the steps, and provide a reasonable experiment she could use to test a rational hypothesis.
