Scientific Inquiry Test

Master science experiments! Learn the scientific method, how to write hypotheses, and identify variables.

What is the Scientific Method? A scientific way to design a graph. A process used by scientists to explore observations and answer questions. A list of materials for a science experiment. Fill in the missing blanks of the scientific method 1. Ask a Question2. Background Research3. State a Hypothesis4. Test with an Experiment5. Collect and Analyze Data6. Draw Conclusions and Communicate Results Match the word with the definition. Hypothesis An educated guess or prediction. Procedure A specific set of step by step directions. Conclusion the end result of any experiment. Observation information you gather using your 5 senses. A fact. What are your 5 SENSES used to make a qualitative OBSERVATION? 1. Sight2. Hearing3. Smell4. Taste5. Touch What is the variable that the scientist changes in the experiment? Independent Dependent Control What is the variable that you need to keep the same throughout the experiment? Independent Dependent Control What is the variable that you measure and observe in an experiment? Independent Dependent Control Read the prompt then identify the variables. Daniel wanted to know which brand of paper towels could hold the most drops of water before leaking. He went to the store and purchased three different brands, Bounty, Scott, and Viva. When he returned home, he took out three identical glasses, one eye dropper, and a container of water. To be fair, he measured each paper towel piece to ensure they were all the same size. Then he began his experiment and put a piece of paper towel over a clear plastic cup and used a rubber band to hold it down. Then he took an eyedropper and counted how many water droplets each paper towel held before leaking through into the cup. Independent Variable Dependent Variable Control Variable(s) Read the prompt then identify the variables. While at school, Jamal saw his teacher do an experiment with Mentos candy and Diet Coke. He was so fascinated of the chemical reaction that he decided to complete his own experiment at home with different brands of diet soda to see if the reaction was the same. He tested with Diet Dr. Pepper, Diet Pepsi, and Diet Root Beer. He made sure to use the same level surface for each experiment. He also dropped only one Mentos candy in each soda at six inches above the entrance to the bottle. Jamal measured the reactions with a meter stick. Independent Variable Dependent Variable Control Variable(s) Determine the best example of a hypothesis: If I add 5 hour energy to my breakfast, then I might go crazy during school. I think that 5 hour energy will help me stay awake in class. They say it has caffeine so it might keep me awake. If I add 5 hour energy to my breakfast routine, then my heart rate will increase because 5 hour energy is full of caffeine. Make a hypothesis for the following question below using the “if….then” format: Will using Tide, Dirt Be Gone, or Shine for a Dime clean my clothes the best? What is the Engineering Design Process? An assembly line that builds car parts. A computer program about engineering. A series of steps that engineers follow to come up with a solution to a problem. If an engineer is testing a new product and notices that it does not always perform well, the engineer should: Ignore the test results and continue to the next step of the Engineering Design Process. Go back to an earlier step of the Engineering Design Process and change the design to try to fix the product, then test the product again Quit, because only bad engineers have product ideas that are not perfect. A test model of a product is know as a: technology example prototype product The testing step of the Engineering Design Process usually involves several rounds of testing, finding new problems, and redesigning and testing again, before finding the final design. true false If you finish early...
