1 Which of the following would you measure using a balance? mass

2 Using one or more of your senses to gather information is called observing.

3 If you conduct an experiment and draw conclusions that are based on your beliefs rather than the facts, you are using subjective reasoning.

4 Mass and weight are different because weight measures the force of gravity on an object and mass is the amount of stuff in an object.

5 Observations that deal with descriptions that cannot be expressed in numbers are called qualitative observations.

6 The metric system of measurement is based on the number 10

7 Jonathan notices that every time he uses a certain bird food in his bird feeder, blue jays land on the feeder. He concludes that blue jays prefer this food more than other birds do. What type of reasoning is Jonathan using? inductive reasoning

8 Making decisions and drawing conclusions based on available evidence involves using which kind of thinking? a.subjective b. Deductive c.Curious d. objective

9 Which of the following would you measure using a graduated cylinder? Volume Mass Length temperature

10 For which of the following would the kilometer be the most appropriate unit of measure? The distance from Pensacola to Destin. Length of a lady bug Very tall giraffe Wing span of a seagull

11 For which of the following would the millimeter be the most appropriate unit of measure? Length of a ladybug Distance from Talahassee to Ft. Walton The height of a tall person The wingspan of a herring

12 The basic unit of length in the metric system is the meter

13 How many meters are there in a kilometer? 1,000

14 The amount of space an object takes up is its volume

15 To calculate the density of an object, you would Divide its mass by its volume

16 The official SI unit of temperature is Kelvin

17 If the notebook box measures 6 cm high, 7 cm wide, and 20 cm long, how would find out the volume? Multiply length X widthXheight

18 In SI, the kilogram is the basic unit of mass

19 A metal washer has a mass of 0.27 g and a volume of 0.1 cm 3. What would you do to find the density? Mass/volume

20 To calculate the density of an object, you multiply mass by volume. ____________________ (T/F) False - Divide

21 A variable that is purposely changed to test a hypothesis is a(n) independent variable.

22 Which of the following is not a way to gain scientific knowledge? a.through experimentation b.through observation c.by making models d.by making assumptions

23 True or False Experimental bias is a mistake in an experiment's design that makes a particular result more likely. ____________________ True

24 When you try to solve a problem, it is important to use scientific reasoning. (T/F) True

25 Proposing an explanation for the changing colors of the sky is an example of a hypothesis. T/F True

26 When doing an experiment is not practical, hypothesizing and modeling are two other ways of gaining scientific knowledge. T/F False - observation

27 The kelvin is the official SI unit for ____________________. temperature

28 To measure objects smaller than a meter but still visible to the unaided eye, scientists would use the centimeter or kilometer.(T/F) ____________________ False - millimeter

29 A scientist would most likely use the Kelvin scale to measure daily temperature. T/F False - Celsius

30 If you state that your basketball team will win tonight’s game because your team has always beaten the other team in the past, you are making a(n) ____________________. prediction

31 ____________________ is the process of grouping together items that are alike in some way. Classifying

32 Scientists who possess the attitude of ____________________ always report their observations and results truthfully. honesty

33 A scientist’s open- mindedness should always be balanced by ____________________, which is having an attitude of doubt. kilogram

34 Density is a measure of how much mass is contained in a given ____________________. volume

35 A scientist’s open- mindedness should always be balanced by ____________________, which is having an attitude of doubt. Skeptism

36 A common tool used to measure length is the ____________________. Metric ruler

37 Temperature is measured using a(n) ____________________. thermometer
