It also has been described as having as many as ten and as a few as three steps. For the purposes of junior high school science, Numan has chosen to use the 6-step Scientific Method. Please understand that it is not the"Scientific Method" because there is no one true "Scientific Method." The 8H Scientific Method consists of the following steps: ** 1. STATE THE PROBLEM ** ** 2. COLLECT INFORMATION ** ** 3. FORM A HYPOTHESIS ** ** 4. TEST THE HYPOTHESIS ** ** 5. OBSERVE, RECORD AND STUDY THE DATA ** ** 6. DRAW A CONCLUSION ** For a detailed look at the steps of the Scientific Method try this website: [|Janice Van Cleave's Scientific Method] ** EXPERIMENTS ** **The 4 steps of an experiment are:** • **Problem** • **Procedure** • **Observation** • **Conclusion** ** Here are some websites with experiments you can do at home: ** **[|The Science Explorer]** **[|Home Experiments]** [|**Edible/Inedible Experiments**] ** [|Hunkin's Experiments]  ** ** [|Kid Science]  **
