  1. Steps to Scientific Inquiry

  2. Working like a scientist is easy! All you have to do is memorize this “word”… QOIHEDC Each step of scientific inquiry corresponds to one letter in the “word”. These letters represent the first letter of each word involved in scientific inquiry!! I’ve created a sentence that will help you memorize these steps. Here are two clues to help you!!

  3. ueen QOIHEDC as ce rink livia's old veryone's Now, what do those words really stand for when we are talking about scientific inquiry?

  4. Pose a QUESTION Scientists usually begin an investigation with a question about something that is unexplained. Ex: Does the shape of ice affect how quickly the ice melts? ?

  5. After they pose this question, scientists make and OBSERVATIONS INFERENCES. Observations involve using one or more of your senses to gather information. Ex: color of the ice, surface texture of ice, area of the ice Inferences are interpretations (or assumptions) based on observations and prior knowledge. Ex: The ice was made from water. ?#6 ?#3

  6. Develop a HYPOTHESIS Ex: The shape of an object (ice) has no effect on the speed of melting. A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. It must be something that can be tested. After a hypothesis is tested once, it must be tested several other times to make sure the results are consistent. ?

  7. Design EXPERIMENTS Variables – all the factors that could affect the outcome of an experiment ?#5 Responding variable – the variable that is affected by the factor that scientists change (Ex: time it takes for the ice to melt) Manipulated variable – the factor that scientists change (Ex: shape of ice) Controlled experiment – one in which there is only one manipulated variable and all other variables are kept constant ?#2

  8. While conducting an experiment, scientists collect DATA. Data – facts, figures and other evidence collected in an experiment. It comes in the forms of descriptions or measurements. Once all the data have been collected, scientists need to interpret, or find the meaning of, these data. Interpreting data involves looking for patterns or trends. Data can be displayed in: diagrams, or graphs. tables Ex: ?

  9. Drawing CONCLUSIONS After all data are interpreted, scientists are ready to draw a conclusion. Sometimes the data will support the hypothesis. Sometimes it will show the hypothesis is incorrect and that’s OK. Eliminating a hypothesis is as important as proving it. Sometimes no conclusion can be reached. This means that scientists need to design more experiments to gather more data. Usually any findings will lead to a new question and a new experiment!! Ex: The experiment was conducted 5 times. The long rectangular shaped ice melted an average of 4 minutes before the square block. This data does not support my hypothesis. I will continue this experiment with larger volumes of ice in the same shapes.
