Procedures
You are almost ready to conduct your experiment, but before you start, you must create detailed step by step directions for your experiment. Your procedures must be easily understandable so anyone else could follow your directions to conduct the experiment, and they should get the same results. Think of procedures as directions to make a peanut butter and jelly sandwich. You would first explain about the ingredients, then how to make it, then how to eat it.

Steps for writing procedures: Notice that you should include the IV, DV, and CV.

  1. Describe the materials that are needed.
  2. IV: Explain how to prepare the IV for the experiment
  3. CV: Describe how to conduct the experiment.
  4. DV: Describe how to measure your experiment.

Here is an example procedure:
Scientific Question: How does the weight of a magnet affect the number of paperclips it can hold?
IV: weight of the magnet
DV: number of paperclips
CV: size of the paperclips, shape of the magnet

Procedures:

  1. Collect 3 paperclips with different weights and some paperclips.
  2. Measure the weight of each magnet in grams and record this on your data table.
  3. Place one magnet at a time into a stack of paper clips and lift it up.
  4. After one second, count the number of paperclips the magnet picked up, record the number on the data table, and repeat the steps for 2 more trials.
