  2. Read each question and answer in the space provided. 21. What is the mass shown here on the triple beam balance. Don’t forget to write the unit that mass is measured in. 22. Measure the volume of water before and after an object is added to a graduated cylinder. Use these measurements to determine the volume of the object. a. Volume before: ____________ b. Volume after: ____________ c. Volume of object: ____________ 23. Use the data table below to make a line graph. Make sure to give your graph a title, labels for the axes, and units. 100 200 300 10 20 30 40 50 60 70 1 2 3 4 6 5 4 3 2 1 6 5 4 3 2 1

  3. For questions 24-26, use the graph below to answer the questions. • 24. How far did the car go in 2 hours? • 25. How far would the graph go if it traveled 6 hours? • 26. Make a data table for this graph. Include a label for each column and the appropriate units for data.

  4. Ms. March heard that a new toothpaste makes your teeth whiter. She wants to know if that is true, so she buys the new toothpaste to try it. Help Ms. March design an experiment to find out if the toothpaste is as amazing as the television commercial suggests. Ms. March’s question: What is the affect of the new toothpaste on the color of teeth? Ms. March’s hypothesis: I think that the new toothpaste will make teeth whiter than the old toothpaste does. Design a procedure that Ms. March can follow to test the toothpaste. 27. Procedure: ___________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ 28.

What data needs to be collected to answer the question? _________________________ _____________________________________________________________________________ 31. Imagine that another scientist performed an experiment to test the very same question. She tested each toothpaste on 100 people and found no difference between the color of their teeth. How might this observation change Ms. March’s hypothesis?
