1
Do you think this experiment was a “Fair Test”?; and what is the reason.
Yes; all plants were tested under the same conditions.
No; the “Tilt-A-Whirl” was broken.
No; the amount of sunlight cannot be measured.
Yes; there were many plants used.
2
Which of the following describes a procedure?
Details of where scientists buy groceries
A plan for designing how to guess inferences
Detailed step-by-step instructions
People who do experiments
3
What would be the best way to present the difference between the bubbles?
Capture a bubble from each soap and freeze it.
Show a video of SpongeBob and Patrick blowing the bubbles.
Use a bar-graph to compare the average size from both.
Write all of the measurements on Patrick’s arms.
4
Which of the following best describes an extraneous variable?
a factor that always changes
a factor that cannot be controlled
a factor that you measure
a factor that remains the same
5
What is a hypothesis?
an educated guess
a guess of what will happen
an educated prediction
an educated predicament
6
Why do we make calculations in science?
To test a students ability to use a calculator
To practice math skills before performing an experiment
Figure out what students know about operations and numbers
Help us understand what happened using a universal language
7
Which of the following is a claim that is supported by the evidence?
Radishes grow most with 16 or more hours of sunlight per day
All radishes grow at the same rate.
The amount of sunlight makes no difference in radish growth.
The best conditions are lots of water and < 8 hours of sun
8
Which “Science and Engineering Practices” should you use?
“Using Mathematics” and “Engaging In Argument From Evidence”
Developing & Using Models and Analyzing & Interpreting Data
“Using Mathematics” and “Analyzing and Interpreting Data”
Engaging in Argument from Evidence, Developing Models
9
Why do we put data into charts and graphs?
So the numbers will stay in order
So the results don’t get lost
So the results are easy to understand
So the results would not get mixed up
10
Could the students use the evidence to
explain
the plant growth?
No, because water does not affect growth.
Yes, because the data was confusing.
No, because sunlight does not affect plant growth.
Yes, because sunlight is involved in plant growth.
11
What is science?
A process for gathering background information
A class that you have to take in seventh grade
A way of annoying students by teaching them things.
A process for gaining knowledge and understanding
12
What claim could be made from this experiment and what evidence supports the claim?
“Regulobubble” produces larger bubbles. Larger average size.
UberBubble” produces larger bubbles. Larger average size.
“UberBubble” produces larger bubbles. the commercial said so
The averages of both bubble sizes were equal.
13
What is data and why do we collect it?
Recorded information that is used to perform an experiment
Stuff you use to figure out what to do in an experiment
Recorded information that is gathered as evidence
Recorded information about what to do in an emergency
14
In
w
hich group did the plants have the most average growth?
group 4
group 1
group 3
group 2
15
Which of the following best describes an independent variable?
the factor that you measure
factors that remain the same
factors that always change
a factor that you choose to change or test
16
Which of the following describes a variable?
something that can change
A green plant you eat for dinner
an educated prediction
a guess of what has happened
17
What is a conclusion?
A summary of what was used in an experiment
A list of things used in an experiment
A summary of what you did and what happened
A graph of the results
18
Was the claim made in the TV commercial supported by the evidence from the experiment?;
No, “UberBubble” produced larger bubbles
No, “UberBubbles” were not twice as big
Yes, “Regulobubble” produced larger bubbles
Yes, “UberBubble” produced larger bubbles
19
What was the dependent variable in this experiment?
soil type
amount of sunlight
amount of water
plant height
20
Why do we put data into charts and graphs?
So the results are easy to understand
So the results don’t get thrown away
So the numbers will stay the same
So the results don’t get lost
21
Which “Science and Engineering Practices” should you use to figure-out what happened ?
“Using Mathematics” and “Engaging In Argument From Evidence”
“Using Mashed Potatoes” and Analyzing and Interpreting Data.
Developing and Using Models and Analyzing, Interpreting Data
“Using Mathematics” and “Analyzing and Interpreting Data”
22
What are Science and Engineering Practices?
A way of looking at data
A way of calculating averages
A process for making graphs of data
Skills and processes for investigating questions
23
What was the testable question that the students wanted to answer?
Does amount of water affect plant growth?
Does type of soil affect plant growth?
Does amount of sunlight affect plant growth?
Does amount of fertilizer affect plant growth?
24
What were the controlled- or constant variables in this experiment?
amount of water, size of pots, soil type, fertilizer
plant height, amount of water, size of pots, fertilizer
amount of sunlight, soil type, fertilizer, size of pots
amount of sunlight, plant height, amount of water, pot size
25
Choose the best hypothesis for the experimental scenario on your review sheet.
“UberBubble” bubbles will be twice as big as claimed.
There won’t be any difference.
“Regulobubble” soap will blow the biggest bubbles.
We think it will be fun
26
Why do scientists use a control group?
to be in control
to be together
to change the variables
to compare data
27
Which group would be considered the control group?
group 4
group 2
group 3
group 1
28
Could there have been any extraneous variables in this experiment?
No, all factors were the same.
Yes, perhaps storm clouds blocked the sun.
Yes, the amount of sunlight
Yes, the amount of water.
29
Which of the following best describes an inference ?
Making measurements of something
An idea that you do an experiment on
Educated assumption of what happened
Educated prediction of what will happen
30
Which of the following best describes a controlled- or constant variable?
an educated measurement
