SCIENTIFIC METHOD What goes into my science notebook…

Date: Ask a question  what you are wondering about (question) Make a hypothesis  similar to a prediction, a statement about what you think will happen. You are trying to prove it (prediction) Conduct an experiment  what you are going to do to find the answer to your question (prodecure) Collect data  this is what you notice while doing your experiment (data) Analyze information  looking at your data and deciding what it means (conclusion or questions Mrs. Nellett gives you to answer) Report Results  telling what you learned (conclusion) Scientific Method

Date: Question  How does the amount of soap in a solution affect the time a bubble will last? Prediction  I think if you add more soap it will make a heavier solution and the bubble will not last as long. Materials  straws (no sharing), stop watch, 6 inch plastic plate, 4 cups of solution (marked A, B, C, D) Procedure  1. Pour a small amount of solution onto the plate to coat it. 2.Place the straw just above the surface at an angle, and gently blow until the bubble fills the indented part of the plate. 3.Start the timer when the bubble reaches the appropriate size. Stop the timer when it pops. Record time. 4.Repeat, completing 3 trials for each solution, taking turns. Bubble Busters

Date: Data  Record the time your bubble lasts You can also write other things you notice in this section Bubble Busters Time Trial 1Trial 2Trial 3 Solution A Solution B Solution C Solution D

Date: Conclusion Questions  1.How would you describe the bubble skin? 2.What is inside the bubble? 3.What was our manipulated/independent variable (the one we were testing)? 4.What was our responding/dependent variable (the one we measured)? 5.“Adding more soap always produces longer-lasting bubbles.” Agree or disagree? Explain. 6.What are you wondering now? If you had to do a similar experiment, what would you like to find out? Bubble Busters

Date: Question  We tested the amount of soap. What variable are you going to test next? Materials  Do you need any extra materials? What are they? Prediction  What do you think will happen? Procedure  What are you going to do to find out if you are right or not? STOP! Your procedure must be approved BEFORE you test it. Data  What did you find out? Conclusion  What did you learn? What could have affected your results? What could you have maybe done differently? What are you wondering now? DYO Bubble Busters
