  5. Row 1, Col 1 What is mass divided by volume? The formula for density. M= D/V D = M/V V = M/D None of the above

  6. 1,2 What is physical change? Change in which the identity of the substance stays the same. Chemical Change Physical Change An Indicator

  7. 1,3 What is a quantitative observation? An example of this type of observation is to say “the tree is 5 feet tall”. Quantitative observation Qualitative observation Variable Observable data

  8. 1,4 What is the freezing or/AND melting point of water? Zero degrees Celsius or 32 degrees Fahrenheit. Melting point Boiling point Freezing point A) and C) All of the above

  9. 2,1 What is the manipulated (independent) variable? – C and D The part of an experiment that is changed on purpose. Dependent Variable Responding Variable Independent Variable Manipulated Variable C) and D)

  10. 2,2 What is mass? The measure of the amount of matter in something. Amount of space an object Takes up B) Mass C) Volume D) Mass in a given Volume

  11. 2,3 What is volume? The measure of the amount of space something takes up. Density Volume Mass Weight

  12. 2,4 What is the hypothesis? This must always be testable in an experiment. Data Question Conclusion Hypothesis

  13. 3,1 What are controlled variables? In an experiment seeing how type of paper affects paper airplane distance: throwing, speed, wind resistance, and design are all examples of these (Clue – they must stay the same as to not ‘mess up’ results) Independent Variables Dependent Variables Controlled Variables Parameters

  14. 3,2 What are chemical properties? Rust, fire, and mixing vinegar with baking soda are examples of these. Physical Change Physical Reaction Chemical Change Chemical Reaction Chemical Properties

  15. 3,3 What are physical properties? Hardness, texture, solubility, and density are examples of these. Chemical properties Physical properties Quantitative observations Chemical change

  16. 3,4 What is 1 g/ml? Density of liquid water. One gram per milliliter (or cm³) One milliliter per gram Zero grams per milliliter (or cm³) Zero milliliter per gram

  17. 4,1 What is 45 mL? When the mass of water is 45 g, it’s volume is _________. No choices… please work out on own

  18. 4,2 What is 3 g/cm^3? The density of a block of wood with volume of 25 cm³ and mass of 75 g. 0.25 g/ cm³ 0.33 g/ cm³ 3 g/ cm³ 9 g/ cm³

  19. 4,3 What is food type and how well students perform? Ms. Dula wants to know if the type of food students eat at lunch affects how well they do in school. The independent and dependent variables are _______________ No choices… please work out on own

  20. 4,4 If the thick paper is used instead of regular paper, then the plane will fly farther. Ms. Relyeawants to experiment with paper airplanes. She thinks that using thick paper instead of regular paper will have an effect on how far the plane will fly. Write a hypothesis based on what she expects. *No choices… please work out on own

  21. 5,1 What is communicating? How scientists check work of other scientists. Making a Conclusion Hypothesis Communicating Asking questions

  22. 5,2 What is (1) the manipulated variable and (2) the responding variable? • Tell the other name for both of • the following: • Independent variable • Dependent variable • *No choices… please work out on • own

  23. 5,3 What is water temperature, the way can is put in water, etc? Ms. Murphy wants to do an Experiment with soda. She thinks that if she puts Diet Coke and Regular Coke into water, then the Diet soda will float. What are two variables that she will need to control? *No choices… please work out on own
