When you are creating your question: • Make sure to think about the items on the checklist • Make sure you are testing something: • Ask Yourself: what is the experiment that will go with my question. 3. A Demonstration is not an experiment!
Example: Good Question • How do different dissolved substances affect the evaporation rate of water? • Experiment is dissolving different substances and timing how fast water evaporates • Does the type of shampoo affect how often my dog scratches himself during the day • Experiment is washing dog with different types of shampoos and recording how often he scratches himself
Example: Bad Questions • How can I make a lava lamp? • Making a lava lamp is not an experiment • How do plants grow? • Watching plants grow is not testing anything • What color water grows plants the best? • This is an experiment but it is too easy for your grade level and is not in our topic list.
When making up your question remember you need to have: • Independent Variable: The thing that you will change • Dependent Variable: the thing that will change when you change the independent. If you don’t have an independent and dependent variable, then you don’t have a question!
