Scientific Method and Graphing

        Help!  

Question
Answer
show The number of candy bars because that is what Mrs.Brandt set different in each class or trial.  
🗑
In the Chocolate and the Scientific Method example, what was the dependent variable? Why?   show
🗑
show 2nd hour. They were promised no candy. They had no changes from a normal quiz so the results of the other classes could be compared to them.  
🗑
show Same quiz, same number of boys and girls in the classes, same age, same ability, same backgrounds  
🗑
show Trials or groups go first. Classes are the experimental groups in this experiment, so 2nd hour, 4th hour, 6th hour, 7th hour  
🗑
show Independent variable goes next, so number of candy bars in this experiment: 0,1,2,3  
🗑
In a data table for the Chocolate and the Scientific Method, what would go in the third column and why?   show
🗑
In the Chocolate and the Scientific Method example, what was the problem?   show
🗑
In the Chocolate and the Scientific Method example, what was the hypothesis?   show
🗑
show The more candy bars promised, the better average scores the classes got on a quiz.  
🗑
What should Mrs. Brandt do at the end of this experiment and why?   show
🗑
show Science is a method for studying the natural world. Science looks for patterns in nature  
🗑
What is the name for the organized set of investigation procedures used by scientists the world over?   show
🗑
show State the problem, gather information, form a hypothesis, test the hypothesis, analyze the data, draw conclusions  
🗑
show Hypothesis  
🗑
show Prediction  
🗑
show Experiments  
🗑
The variable in an experiment that is adjusted or set by the experimenter   show
🗑
show Dependent variable  
🗑
A variable that does not change in an experiment   show
🗑
A group in an experiment that is used for comparison. No changes are made to it.   show
🗑
show Bias  
🗑
This is a table used in an experiment for results.   show
🗑
show Scientific Theory  
🗑
This is a statement about something that always seems to be true. It usually answers the question “What?”   show
🗑
show Technology  
🗑
show Engineering is the field of study that applies scientific knowledge to build or make something.  
🗑
What Latin word does science come from? What does that word mean.   show
🗑
show Earth science, life science, and physical science.  
🗑
show Earth Science  
🗑
What branch of science studies matter and energy or chemistry and physics?   show
🗑
show Life Science  
🗑
show matter  
🗑
Physics is the study of ______ and what it does to matter   show
🗑
show Investigations  
🗑
Scientific investigations can involve ______, ________, ________.   show
🗑
____ are controlled investigations where one variable is changed to see how something else changes.   show
🗑
show Observations  
🗑
show Models  
🗑
How is an observation different from and inference?   show
🗑
show Line Graph  
🗑
show circle or pie graph  
🗑
show A bar graph  
🗑
show Groups or Trials  
🗑
On a data table, what variable is placed in the 2nd column?   show
🗑
show The third column.  
🗑
When one variable increases as the other increases, and produces a straight line sloping up, we say they are ____proportional   show
🗑
If two variables are inversely proportional, one goes down as the other goes up, and the line produced slants   show
🗑
show no motion  
🗑
On a position (distance with direction) vs time graph, what does a straight line sloping up represent?   show
🗑
show constant speed backwards or in a negative direction  
🗑
On a position (distance with direction) vs time graph, what does a curving line sloping up represent?   show
🗑
show constant acceleration forward, or speed is getting faster each second at a constant rate  
🗑
show constant deceleration forward, or speed is getting slowerr each second at a constant rate  
🗑
On a velocity (speed with direction) vs time graph, what does a straight horizontal line represent?   show
🗑
show speed  
🗑
what does the slope of a v vs t graph give you   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
