Essential+Question+Answer

When Anna first began to design her experiment, she first formulated her Essential Question. Then she designed an experiment that would help her gather data that might provide an answer to the question. When reading about an experiment, you can often see obvious connections between the independent variable and the type of question that is being investigated. If you identify the changes being made in the experiment, then you can usually work backwards and figure out the question that is being asked. Here are possible Essential Questions for Anna's experiment:


 * 1) How much Diazinon is needed to protect tomato plants from an aphid infestation?
 * 2) What is the least amount of Diazinon needed to keep aphids from infesting tomato plants?

You may have a variation of these two examples, but you must mention Diazinon, aphids, and tomatoes in your question. Now, keeping **TAB** in mind, here is how you should have presented your answer to this question:


 * Anna's Essential Question could be: //What is the least amount of Diazinon needed to keep aphids from infesting tomato plants?// I believe this is the EQ because Anna is varying the amount of Diazinon she is using and monitoring the aphid population in her experiment. This looks like she is investigating a connection between the poison and an insect that likes to infest tomatoes.**
