TIPS FOR ANSWERING LONGER ANSWER QUESTIONS

Which command word is used?These tell you what to do. Explain, Describe, Discuss, CompareCheck you know what they all mean.

Underline or circle key words

Explain why the amount of fertiliser used is increasing, and describe the damage that fertilisers can cause to life in rivers and lakes.

What key words might be needed to answer the question?Write them down. Make sure you know what they mean. Organise them, either in groups, or in an order.

How many marks is it worth?Have you written enough?

More KEY WORDS!Check your answer...Level 35-6 marksHave you used any of the key words?Have you made some key points?Level 00 marksNoYesHave you used lots of the key words?Have you fully described any of the key points?Is there a logical order?Level 11-2 marksNoYesHave you used all the key words correctly?Have you justified your conclusion using correct science?Is your spelling faultless and your report logical?Level 23-4 marksNoYesMore KEY WORDS?

Check the ORDER?Think more SCIENCE!

More DETAIL!

Check your SPELLING!

Command WordsCalculate work out a number. Use a calculator, show your working.Compare write about ways in which two things are the same, and how they are different.Describe write a detailed answer that covers what happens, when it happens and where it happens. Your answer must include facts or characteristics.Discuss write about the issues linked to a topic. You many need to give arguments for and against something, or show differences between ideas, opinions and facts.Estimate suggest a rough value without doing a calculation. BE CAREFUL Calculate a best estimate = calculate an average include your calculationsExplain write a detailed answer that says how and why things happen.Evaluate use the provided facts, data or information. Write about these and give your own opinion/conclusion.Justify give some evidence or an explanation to support why you gave that answer.Outline give the key facts, such as in a process give the steps in a correct order.Predict look at data and suggest a value or result. Use patterns and trends to support your answer.Show give each step you took in a calculation, write it down clearly.Suggest use your science knowledge in a new situation to come up with a reasonable answer.
