Scientific Method
Problem/Purpose • State the problem in the form of a question that includes the independent and dependent variable • (Will a hard boiled egg float in salt water? )
• Hypothesis If the amount of salt added to the water increases, then the hard boiled egg will float) • Educated guess to solving the problem that includes the independent and dependent variables. • If the independent variable increases or decreases, then the dependent variable will increase or decrease.
• Variables • Parts of the experiment independent constant
• Independent (I. V. ) The scientist (you) change on purpose. (amount of salt)
• Dependent (D. V. ) • The response from the change made to the independent variable. • Results • (float or not float)
• Constant (C. V. ) • The item that does not change at all. It stays the same Same beakers, same amount of water, same type of salt, Same spoon, same classroom. • Control • No variable is applied to the item
• Experiment constant no change • Design an experiment to test your problem using the three (3) types of variables (test 3 times for accuracy) independent amount of salt dependent float or not float
Record Findings • Data Table • Make a data table showing your results • Graph • Make a graph to visually show your results.
• Conclusion • Restate your hypothesis with the results from your experiment • Should be at least 3 paragraphs formal experiments.
