Welcome • Please sign in at the front. . • Please be aware that you will be put into a team: 1, 2, 3, or 4, so please go ahead and break yourselves up into these teams so that we can get started quickly. If anyone comes in late, please take them into your teams. Don’t just leave them hanging.
Getting started • This review will be posted on my SI resources site (See Vista), so there’s no need to write everything down. (unless you just want to) • This session is much different than a regular SI session: this is a fast-paced review rather than going into the material in depth. • Shameless plug: People who come to my SI sessions typically do better on their tests. Please come, having more people generally makes the sessions more enjoyable.
Rules • Each team will have a chance to work together to answer questions in order: Team 1, 2, 3, 4 • If the team cannot answer all parts of a question, the question will be passed to the next team (this is separate from the bonuses). • Please put your notes away unless you are writing in them, no points will be awarded for finding info in your notes.

Vocabulary I for 100 Fill in the blank: A ______ is a reasonable guess of what will happen in a set of experiments a) Prediction b) Hypothesis
A hypothesis is a reasonable guess of what will happen in a set of experiments a) Prediction -a specific educated guess as to what will happen specifically under a set of circumstances: Ex. in the fish lab experiment, “A change in water temperature will have an impact on fish growth. ” b) Hypothesis ex. in the fish lab, “Environmental factors affect fish growth.
Vocabulary I for 200 What is an ecological footprint?
An ecological footprint is a person or group of people’s total impact on the environment.
Vocabulary I for 300 What is the “Tragedy of the Commons? ”
The tragedy of the commons occurs when there is a public unregulated resource that is overused to the point of severe deterioration or even destruction of that resource.

Vocabulary I for $400 There are three kinds of variables we talked about: – Independent – Dependent – Controlled Give an explanation and example of each
Independent = does not depend on the other variable (temperature) Dependent = depends on the independent variable (average weight of the fish) Controlled variables = held constant during the experiment (light, age of fish, dissolved oxygen)
Places for 200 What supposedly happened to the trees on Easter Island?
In addition to using the trees for everyday life (boats, firewood, homes, etc. ), the native people of Easter Island used the trees to transport Moai(sp? ) – large stone statues. Eventually, they used up all of the trees.

Extra – 500 Name 3 places visited in Earth on Edge, and describe the issues discussed in each one
- Kansas farms: topsoil erosion because of over tilling, fertilizer and pesticide run-off causing dead zone in the Mexico - South Africa: Water shortage caused by thirsty non-native trees.

Extra – 500 Name the other 2 places visited in Earth on Edge, and describe the issues discussed in each one
- Brazil: Coral reef destruction because of pollution and tourism, mangrove forests threatened by pollution from sugar cane crop runoff, shrimp farming, and building development - Mongolian grasslands: overgrazing due to population’s increasingly sedentary lifestyle, more people herding, and no one telling them to move around.
Extra - 500 What does the p – value have to be to reject the null hypothesis? What does this mean?
P-value (probability that the null hypothesis is correct) must be less than. 05 (5%). The null hypothesis is the hypothesis that there is no change caused by whatever you are testing for. In the fish lab, the null hypothesis would be that environmental factors have no impact on fish growth. If the p-value <. 05, you can say with 95% or more certainty that your results were not due to chance.
Extra – 200 Bill Ensign is studying the impact of hydrologic alteration(such as building dams) on what?
Fish
Extra What is peer review? Why is it necessary to sound science?
Peer review occurs after an experiment has found conclusive evidence. The findings of the experiment are looked at by other scientists to check its validity – making sure that the experiment was done well and that there were no important factors not taken into account.
