Question/Topic

posted Mar 22, 2015, 2:36 PM by A. N. Fletcher

A STEM Fair project starts with a question.  For most students, a difficult part of STEM Fair is selecting a good question (topic).  It is important the question be one that is interesting to the student.  The question should be one that can lead to an experiment project where something is changed and the result is measured.

A good question...
  • must lead to an investigation (experiment) not a report, a demonstration or a model.  The question may ask about the effect of one thing upon another.
  • should be one from which you can collect data (ideally measurements or direct observations) rather than opinions.
  • should be specific rather than really broad
  • is one which the materials needed to experiment with are easy to find.
Examples of good questions:
  • How does temperature affect the bounce of a ball?
  • What type of conditions do mealworms prefer?
  • What shape of container will allow water to evaporate the quickest?
  • Does the drop height of an object affect the size of the crater it will make?
Examples of poor questions:
  • How do volcanoes erupt?  This questions is poor because it is a model, not an experiment, is too vague (broad), and will not involve data collection.
  • Why are there craters on the moon?  This question is not an experiment and would require only research, not scientific experimentation to answer.
  • How do bean plants grow?  This question is too broad and would require research rather than experimenting and collecting data.

The HYPOTHESIS/PREDICTION of the STEM Fair Project

posted Mar 20, 2013, 5:18 PM by A. N. Fletcher

The Hypothesis/Prediction answers the QUESTION being investigated...a "because" statement must be included. The prediction is a reasonable guess about the outcome of the experiment and suggests a possible reason for this outcome.  Many times, the word hypothesis is used instead of prediction.  A hypothesis is a prediction that can be tested.  It should be based on prior knowledge, observations, or research and is accepted or rejected by the results of the investigation.  It should include the expected cause and effect in a given circumstance or situation.  Information from research or prior knowledge should be part of a hypothesis statement.

Do you want to get a jump on your STEM Fair Project?  Follow the Parent Involvement - STEM Fair document below.

Deadlines/Timelines will be posted at a later date.

The VARIABLES of the STEM Fair

posted Nov 29, 2010, 1:00 PM by A. N. Fletcher

There are 3 types of variables that must be considered

INDEPENDENT VARIABLE
  • There is only one Independent Variable
  • This is the one thing that will be changed on purpose to find out what effect it has on something else.
    • Are you changing the height, temperature, amount, liquid, etc.
  • Example, if you are testing whether or not water temperature has an effect on the dissolving time of Alka-Seltzer, then the Independent Variable will be the temperature of the water.

DEPENDENT VARIABLE
  • There is only one Dependent Variable
  • This is what factor is being observed or measured to see if it is affected by the change the Independent Variable made.
    • What are you measuring and how?
  • In the example above, the Dependent Variable will be the dissolving time of the Alka-Seltzer.

CONTROLLED VARIABLES
  • All other materials in the experiment must remain exactly the same.
  • In the example above, the thermometer, Alka-Seltzer, type of water, cups, etc.

The PROCEDURES of the STEM Fair

posted Nov 29, 2010, 12:45 PM by A. N. Fletcher

  • The procedure should include all the steps that were followed in setting up the experiment AND collecting the data.
  • The procedures should be written in a clear, sequential manner so that someone else could follow the same steps to complete the experiment.
  • Numbering the steps is useful.

The MATERIALS of the STEM Fair

posted Nov 29, 2010, 12:40 PM by A. N. Fletcher

- Materials should include the equipment and supplies that were used to complete the experiment.

- Materials need to be listed in specific amounts and sizes for the ENTIRE experiment...including 3-5 trials.

Example:

One 500 mL beaker
3 plastic cups
One hand lens
Masking tape labeled A, B, and C

- Metric Units should be used.

1-10 of 14
