### Scientific Method Quiz Review

Let’s check how you did?

Use this PowerPoint as a review!

A:1 B:27 C:19 D:30
• Jen enters the 5th grade science fair with a project about candles. She asks "Will the temperature of the air affect how fast a candle burns?
• That is her Hypothesis.
• That is her Conclusion.
• That is her Problem (a:c, b:b, c:d, d:c)
• That is her Observation.
A:2 B:29 C:19 D:30

In second grade, Jen asked "Which color of candy do kids prefer?

“ What would be an important constant or controlled variable in her experiment?

• Use the same candy that comes in different colors, but the same flavor. (A:b, B:a, C:b, D:a)
• Do the experiment right before lunch so the kids at really hungry.
• Ask each person what is their favorite kind of candy

Mrs. Apex's 3rd grade is learning multiplication facts. She notices that Jay and Jen are doing really well. She asks them if they are doing extra facts worksheets. Jay replies that he has a fun computer program that does multiplication facts. Jen comes over and plays the game with him. Mrs. Apex is almost sure that the old fashioned way of paper worksheets is best & that Jay & Jen are not the norm. So, Mrs. Apex decides to do an experiment. Mrs. Apex divides her class in half. There are five boys and five girls in each group. Group A practices 5 times tables on paper worksheets for 10 minutes each day. Group B practices 5 times tables on the computer program for 10 minutes each day.At the end of one week all the children take the same quiz. The children in Group A score 5As, 2Bs, 2Cs, 1D. The children in Group B score 7As, 2Bs, 1F. After the fifth week, Mrs. Apex tests the children on their multiplication facts again. Group A (paper) scores 3As, 3Bs, 4Cs. Group B (computers) score 8As, 2Bs. In the computer group - girls and boys did equally well. Her hypothesis was that paper worksheets will be the best way to teach math facts.

A:3 B:16 C:2 D:11

Mrs. Apex might form which hypothesis?

• If students practice multiplication facts on a paper worksheet, they will improve their math scores. (A;a, B:a, C:a, D:b)
• The students like the computers more than they like her.
• Computers will replace teachers.
• Practicing multiplication facts on a computer might help test scores..
A:4 B:10 C:8 D:7

Mrs. Apex decides to test her hypothesis. How can she do this?

A:5, B:9, C:5, D:3

In Mrs. Apex's experiment, what is the independent variable?

A:6, B:13, C:4, D:4

Mrs. Apex divides her class in half. There are five boys and five girls in each group. Group A practices 5 times tables on paper worksheets for 10 minutes each day. Group B practices 5 times tables on the computer program for 10 minutes each day. What is the controlled variables?

A:7, B:12, C:1, D:4

The principal, Mrs. Integer tells Mrs. Apex to write down exactly what she is doing step by step. In the scientific method this is called ...

• Conclusion
• Procedure (A:b, B:d, C:d, D:b)
• Hypothesis
• data
A:8, B:14, C:6, D:10

At the end of one week all the children take the same quiz. The children in Group A score 5As, 2Bs, 2Cs, 1D. The children in Group B score 7As, 2Bs, 1F. The quiz scores are an example of ...

• Conclusion
• Hypothesis
• Data (A:c, B:a, C:c, D:c)
• Procedure
A:9, B:15, C:3, D:5

After one week, does Mrs. Apex have enough data to make a conclusion?

A:10, B:11, C:7, D:8

Mrs. Apex decides to ask the school board to buy math facts software. She wants to show her data in her presentation. She should

A:11, B17, C:9, D:6

After the fifth week, Mrs. Apex tests the children on their multiplication facts again. Group A (paper) scores 3As, 3Bs, 4Cs. Group B (computers) score 8As, 2Bs. In the computer group - girls and boys did equally well. Her hypothesis was that paper worksheets will be the best way to teach math facts.

Jay digs a large garden for his mother. The site she chose is near some trees. About half the garden is shaded all afternoon. The other half gets sun all day long. In August, Jay notices that the tomato plants on the sunny side of the garden are 2x taller than the shaded ones. The sunny side plants have 20 tomatoes on each plant. The plants on the other side are short and have only 10 tomatoes on them. He tells his mother what he has noticed. This is an example of ...

• Hypothesis
• Observation (A:b, B:a, C:c, D:a)
• Conclusion
• Data collection
A:13, B:28, C:24, D:21

You create a science fair project. It takes 6 weeks to collect all the data. In looking at the data, you find your hypothesis was wrong. You should:

A:14, B:26, C:21, D:20

The dependent variable

Mrs. Membrane decided to make scrambled eggs. When she tried to break an egg, she found it was hard cooked. Jen said she could tell the difference without breaking the shell. Jen spun the first egg on the counter. It turned fast like a top. She touched it to stop it. It stopped. She spun another one. It also stopped when touched. The third egg did the same. The fourth egg turned. When she stopped it, it rotated slowly when she let go. Jen said it was raw.
A:15, B:19, C:25, D:15

A:16, B:23, C:11, D:24

To test your hypothesis about the eggs, you decide to conduct an experiment. You buy a dozen white chicken eggs. The variable you will change will be

A:17, B:20, C:22, D:29

The controls in the egg experiment should be

A:18, B:25, C:18, D:26

The variable that you change in the experiment.

• Control
• Independent (A:b, B:d, C:c, D:d)
• Dependent
• Responding
A:19, B:7, C:10, D:27

The variable that changes because you changed the other variable. (This is the data you collect.)

• Independent
• Dependent (A:b, B:c, C:d, D:a)
• Controlled
• Manipulated
A:20, B:24, C:16, D:23

The variables that do not change in an experiment are called

• Independent
• Dependent
• Controlled (A;c, B:c, C:a, D:c)
• Stubborn
A:21, B:3, C:14, D:17

An experiment is being done to determine how light affects the growth small zinnia plants. One plant is placed in full sunlight, the second in a shaded area, the third in an unlit closet.

What is the independent variable in the experiment?

• Type of plant
• Amount of light (A:b, B:b, C:c, D;a)
• Type of soil
• Growth of the plant
A:22, B:4, C:12, D:18

The hypothesis of this experiment could be:

A:23, B:5, C:13, D:19

The constants in the plant experiment are: Choose all that apply

• Amount of sunlight
• Type of pot
• Amount of water
• Type of plant
A:24, B:22, C:26, D:13

Good experiments have more than one variable.

• True
• False (A:b, B:b, C:a, D:a)
A:25, B:30, C:27, D:16

In an experiment, there should be only one _________. Everything else should be a ________.

• Control – independent variables
• Dependent variable-independent variable
• Independent variable – control (A:c, B:d, C:c, D:d)
• Trial – proven

A group of students is doing an experiment where they roll a ball down a ramp and then measure how far across the floor it rolls. The factors that are the same each time are:

• the ball

• the ramp, including its length and angle to the surface

• where on the ramp the ball starts from

The students do change the type of surface the ball rolls on. The data theycollected is shown below.

A:26, B:18, C:20, D:28

Graph

Marie and Seth are working on a lab activity where they are tracking some leaves that are floating past them in a rain runoff channel near their home. They have to measure how far the leaves travel in different amounts of time. They place a long tape measure along side of the runoff channel to measure distance. A borrowed stopwatch will let them record the amount of time. They plan to have time intervals that begin at two seconds, and increase by two’s until they get to 20 seconds. The data they recorded is below:
