What are the 3 main types of errors that can happen during an experiment?

human, instrumental, and random

If the experiment begins at 9:00, what is wrong with the setup?

The plants don't have the same initial health or height.

Why is it important to accurately record the procedures and results of an experiment?

So that others can repeat it and get the same results

Ty carried out an experiment involving model parachutes. Which choice is an instrumental error?

The stopwatch’s battery died.

Most of next week's quiz is based on:

Sci Met Quizlet (32-44) and graphs.

The most important reason why it is important to perform an experiment more than once?

It makes your results more reliable.

What is true about the following world population graph?

The world population from 1960 to 2040 will have tripled.

Why should only 1 variable be tested at a time?

It helps us see if any changes occur., It's difficult to compare results w/o one.

Graphs are useful because they...

help form conclusions., organize data., help us see relationships.

Answers

1
What are the 3 main types of errors that can happen during an experiment?
human, instrumental, and random
inaccurate, human, and random
messy, silly, and human
accidental, instrumental, and random
2
A valid conclusion refers back to the hypothesis.
True
False
Meh
3
A valid experiment has...
many constants.
more than 2 variables.
an accurate hypothesis.
few constants.
4
When scientists finish an experiment, they usually discuss…
how they feel about the universe.
how they did such a great job.
the weather.
errors and improvements.
5
What's wrong with this pie graph?
The pieces are not labeled.
The percentages don't add up to 100.
The title is missing
It's missing sunlight.
6
When carrying out an experiment, you should test...
one constant.
two variables.
one trial.
one variable.
7
If the experiment begins at 9:00, what is wrong with the setup?
All of the plants were in the same type of pot.
The plants don't have the same initial health or height.
The plant pots should be much further apart.
There are way too many variables.
8
Why is it important to accurately record the procedures and results of an experiment?
So that others can repeat it and get the same results
So that you can be world famous
So that others can see if you did your experiment correctly
So that you will win a science award
9
Why should scientists perform many trials?
to have accurate results
to be the best scientist ever
to have bad results
to have reliable results
10
Ty carried out an experiment involving model parachutes. Which choice is an instrumental error?
A fire drill happens during one of the trials.
Someone forgets to stop the timer.
The stopwatch’s battery died.
One parachute gets dropped from a different height.

large control
17
The most important reason why it is important to perform an experiment more than once?
It makes your results more accurate.
It's fun!
It makes your results more reliable.
You will impress your friends.
18

The world population has remained constant.
The world population from 1960 to 2040 will have tripled.
20
Why should only 1 variable be tested at a time?
It helps us see if any changes occur.
It's difficult to compare results w/o one.
Mr. G said it was important
One variable is better than none!
21

amount of sunlight.
amount of water.
the plant without water.
plant health.
22
Graphs are useful because they...
help form conclusions.
organize data.
help us see relationships.
have color, neatness and numbers.
