2
$100 Question Scientific Method
What two words must be included in your hypothesis?
3
$100 Answer Scientific Method
If and then
4
$200 Question Scientific Method
What justifies your conclusion?
5
$200 Answer Scientific Method
Data gathered from observations made during the experiment
6
$300 Question Scientific Method
What are controlled variables?
7
$300 Answer Scientific Method
Controlled variables are variables that kept the same for both the experimental and the control groups during an experiment
8
$400 Question Scientific Method
What three things make up a good Experiment?
9
$400 Answer Scientific Method
Having a control group Having only one independent variable Testing the hypothesis many times
10
$500 Question Scientific Method
Name the steps of the scientific method in order
11
$500 Answer Scientific Method
Ask a Question Form a Hypothesis Experiment (procedures) Collect Data Form a Conclusion Communicate your results
12
$100 Question Observations, Inferences, Predictions
What is a Qualitative Observation? And give one example
13
$100 Answer Observations, Inferences, Predictions
A qualitative observation is an observation that does not include numbers Example: The flower is yellow There is a bad odor coming from the milk The cake tastes salty It makes a hollow sound when tapped The owl making a hooting noise
14
$200 Question Observations, Inferences, Predictions
What is a quantitative observation? Give an example?
15
$200 Answer Observations, Inferences, Predictions
An observation that includes numbers Example: The was is 28 degrees There was 2.5 grams of sugar The house is 20 ft. tall
16
$300 Question Observations, Inferences, Predictions
What is the difference between an inference and a prediction?
17
$300 Answer Observations, Inferences, Predictions
Inferences use prior knowledge and observations to make a logical interpretation Predictions use prior knowledge to make a forecast of what will happen in the future
18
$400 Question Observations, Inferences, Predictions
State whether the following sentence is an observation, an inference or a prediction based on the graph More girls ride in a car to school than boys
19
$400 Answer Observations, Inferences, Predictions
20
$500 Question Observations, Inferences, Predictions
State whether the following sentence is an observation, an inference or a prediction based on the graph Students ride the bus because they live too far away to ride their bike or walk.
21
$500 Answer Observations, Inferences, Predictions
22
$100 Question Vocabulary Practice
What is matter?
23
$100 Answer Vocabulary Practice
Anything that has mass and takes up space
24
$200 Question Vocabulary Practice
What is a theory?
25
$200 Answer Vocabulary Practice
A well tested observation for many observations and experimental results
26
$300 Question Vocabulary Practice
What is energy? And give an example of a type of energy
27
$300 Answer Vocabulary Practice
Energy is the abiltiy to do work. The types of energies are chemical, electrical, heat, light, mechanical, and nuclear fusion
28
$400 Question Vocabulary Practice
What is a law and give an example.
29
$400 Answer Vocabulary Practice
A statement that describes what scientists expect to happen every time under a particular set of conditions without attempting to explain it. Example: Gravity. Newton’s 1st, 2nd, 3rd Law, etc.
30
$500 Question Vocabulary Practice
What four vocabulary words represent the skills people need in order to think like a scientist?
31
$500 Answer Vocabulary Practice
Predicting, Classifying, Observing, and Inferring
32
$100 Question Experimenting
Name a hypothesis for the following problem: Will energy drinks increase the activity in mice?
33
$100 Answer Experimenting
If mice are given energy drinks, then the mice will become more active
34
$200 Question Experimenting
A student wants to see if energy drink increases the activity of mice. What would be a control group a student could use for this experiment?
35
$200 Answer Experimenting
Observing the activity of mice that are not given any energy drink
36
$300 Question Experimenting
What would be the independent and dependent variables in the experiment? A student wants to see if energy drink makes mice more active
37
$300 Answer Experimenting
Independent: Giving mice energy drink Dependent: the activity of the mice
38
$400 Question Experimenting
Why do you need controlled variables?
39
$400 Answer Experimenting
Without controlling all other variables (keeping them the same for both the experimental and control groups), you would not be able to determine whether you results were because of the independent variable changing or not.
40
$500 Question Experimenting
Name 4 controlled variables that you would have for the following experiment A student wants to see if energy drink makes mice more active
41
$500 Answer Experimenting
Give the mice the same energy drink Give the mice the same amount of energy drink Use the same species of mouse Observe the mice for the same amount of time Observe the mice at the same time of day
42
$100 Question Let’s talk about Variables
What is an independent Variable?
43
$100 Answer Let’s talk about Variables
The variable that is changed in an experiment
44
$200 Question Let’s talk about Variables
How does the dependent variable relate to the independent variable?
45
$200 Answer Let’s talk about Variables
The dependent variable changes because of the independent variable changing
46
$300 Question Let’s talk about Variables
Name a controlled variable for the following experiment A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.
47
$300 Answer Let’s talk about Variables
The people from the two groups are the same age Gender The people taking vitamins take the same brand The people taking vitamins take the same amount
48
$400 Question Let’s talk about Variables
What is the independent and dependent variable for the following experiment: A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.
49
$400 Answer Let’s talk about Variables
Independent Variable: Taking vitamins Dependent Variable: Life expectancy
50
$500 Question Let’s talk about Variables
Which is the control group and which is the experimental group? A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.
51
$500 Answer Let’s talk about Variables
The people taking vitamins are the Experimental Group The People not taking vitamins are the Control
52
Final Jeopardy What is the difference between a law and a Theory?
53
Final Jeopardy Answer A theory is a well tested explanation for many observations, while a law describes what happens for an observed pattern without attempting to explain it.
