• • Analyze: Consider the different parts of a problem, situation, or equation in order to determine the nature of the whole. Taking something apart to look at its component parts

• • Compare: Examination of similarities and/or differences. Compare implies looking at only similaritieswhile compare and contrast implies looking at similarities and differences. 10th grade students should know the difference between point by point comparison or block comparison and should be able to write in either style.

• • Describe: Give as many details as possible. If the question involves an object or a place, all five senses should be utilized. If the question involves a person or a story, dialogue or conversation may be necessary. If the question involves a person only, an anecdote may be helpful. A web or a list of details created before writing is a good way to ensure that the student provides enough description.

• • Evaluate: The student uses given criteria or comes up with his/her own criteria to judge the role or value of something. This might include explaining the pros and cons and/or consequences of a decision or action. It might ask for a value judgment on a piece of literature or a decision made by a person in history.

• • Explain: The student is asked to give reasons for something. It might be to clarify the function of something, to identify causes for events or relationships, or it might be to examine factors leading up to an incident or a result.

• • Formulate: The student is asked to come up with a new concept, theory, or hypothesis. This is to be done based on information, trends, patterns, observations, etc. An example could be devising a category to classify seemingly dissimilar events.

• • Infer: Students are asked to provide an answer that is not explicitly named or stated in the question or the text. This is done by predicting events or extracting data from a given set of facts.

• • Predict: The student is asked to use knowledge already provided in a piece of reading or in a chart or graph in order to make a statement about what will happen next. For instance, if a component in a process is changed, what will be the consequences?

• • Summarize: Condense the information given in a piece of reading or on a chart or graph into a smaller piece of writing, for instance several paragraphs summarized in one paragraph or one paragraph summarized in one sentence. When asking students to summarize, they should be directed to look at the topic sentences in a piece of writing.

• • Support: Use information from text or charts or graphs to give evidence for a conclusion or argument. Support is more than just the student's opinion. It should be facts, details, or quotations from what has been read or observed.

• • Trace: Describe a path or sequence of events or give an accurate chronology

• Solar energy (heats air and land)

• Elevation (temperature falls with increased elevation)

• Nearness to large bodies of water (humidity and temperature affected)

• Temperature (determines how much water vapor air can hold)

• Organize the following steps to scientifically solve a problem.

• Develop a hypothesis.

• Ask a question based on observations.

• Draw Conclusions.

• Test hypothesis.

• Plan test with materials and methods.

What is the Ozone layer and why is it important?

The ozone is a layer in the stratosphere that absorbs ultraviolet rays from the sun, keeping most of the life harming rays from reaching the Earth’s surface.

Why are there “holes” in the ozone layer over the South Pole?

Chloroflourocarbons (CFC’s) once used in refrigerators, air conditioners, and aerosols were released into the atmosphere. These chemicals decreased the amount of ozone, which created a hole (especially over Antarctica where the ozone tends to be naturally thin.

What is being done about CFC’s?

In 1986 International Congress in Montreal produced a treaty to reduce and then ban CFC production by 1996.
