CHAPT 1 - The scientific method allows the solving of problems and answering of questions. Observations Proposing ideas Testing the ideas Discarding or modifying ideas based on results Hypothesis: proposed explanation for a set of observations Hypotheses needs to be: Testable – it must be possible to examine the hypothesis through observations Falsifiable – it must be able to potentially be proven false Both logical and creative influences are used to develop a hypothesis A hypothesis

HOW DOES TOURISM IMPACT THE ENVIRONMENT The effect of tourism on the environment can be both positive and negative. Each person or group of people will impact the area they visit in a different way. Whether it is in a negative or positive manner is entirely up to the visitor. Let’s consider the NEGATIVE impacts first: POLLUTION - This is probably the biggest negative factor concerning tourism. People have to travel to their destination. It doesn’t matter if it’s by plane to another country or

developments which can prove critical for the wellbeing of their environment. One area that has witnessed degradation in recent years is Galapagos which is an example of a biodiversity hotspot that is threatened by alien species. This island off the coast of Ecuador is home to a huge range of these ‘alien species’ with up to 60% of the 180 endemic plants in Galapagos now considered under threat. There has been 490 introduced insect species on the island‚ and 43 species of other invertebrates – of these

Biology – living organisms Scientific Method – making observations‚ proposing ideas about how something works‚ testing ideas‚ discarding or modifying -allows us to solve problems and answer questions efficiently and effectively. -Ideas about “how things work” = hypothesis. -proposed explanation for one or more observations -scientific hypothesis MUST be testable -must be falsifiable (observations could prove false) Observations Question Hypothesis = imagination‚ intuition‚ chance

stuck and stranded. Another decision that was made by Captain Jack was whether or not to break the promise to his friend that allowed him to explore the Galapagos islands for a few days. Even though he ended up breaking the promise between himself and Maturin‚ an accidental gun wound to another crewmember set the Acheron back towards the Galapagos Islands for medical help‚ which ended up giving Maturin a chance to

Cuttlefish Evolutionary History The cuttlefish are an amazingly developed animal species with many specialised traits that make them perfectly suited to most‚ if not all‚ types of underwater environments. This is the animal this presentation will be looking into. Evolution is commonly described as a theory‚ However that is a common misconception‚ all different types of evolution‚ e.g. Darwinism and Lamarckism‚ are actually considered both fact and theory. As palaeontologist Stephen Jay Gould says

Charles Darwin provided a mechanism for the theory of Biological Evolution‚ which is what separates him from previous researchers. Before Darwin’s theory of biological evolution by natural selection‚ the ancient Greeks were the first to attempt to understand our place in the natural world. Following the Greeks‚ was Aristotle‚ he believed that each living form had attributes that could not be altered‚ therefore‚ fitting in an ordered rank ladder‚ and that human beings were at the top of the ladder
