Writing a scientific procedure
Notes to Parents: Every parent must use their own judgment in choosing which activities are safe for their own children.
These sites will help you gain a greater understanding of variables and writing a procedure. Record the voltage in a table every time it is measured.
You will almost always need many more than three participants! This also makes it much easier for someone else to test your experiment if they are interested in seeing how you got your results. Activity 1: Start Thinking! Dependent Variable The dependent variable is the thing that changes as a result of your independent variable, or the one thing that you intentionally changed.
Do you think you could you follow the procedure? Often it includes a sketch of how to set-up the experiment.
Biology procedure example
How many participants are enough, what is the ideal sample size? For the camera flash push the flash button every 30 seconds and measure the voltage every 5 minutes. Take extra time to carefully read through each step in the procedure and consider the questions below. The procedure is a set of very specific instruction about how you are going to conduct your experiment. Send us a note if you have any questions. This trial is referred to as a control group. Bonus: Follow the procedure and document what happened. Print Key Info Write the experimental procedure like a step-by-step recipe for your science experiment. Take two ice cubes out of the freezer and place one in each bowl. You've done a little bit of research and made a best guess as to what the answer might be. Repeating your experiment more than three times is even better, and doing so may even be required to measure very small changes in some experiments. That way, you can prove what you did and can follow the same procedure if you, or someone else, needs to repeat the experiment. Nothing else should change but this one variable.
Once you complete the activities on this page, you'll be well on your way to a complete experimental procedure!
