$1000400,000,000 M&M’s

If the Mississippi river is nearly 4,000 km long and an M&M is 1cm long how many M&M’s would it take to measure the

Mississippi river?

$200

Make an observation or ask a question

What is the first step in the scientific method?

$400

True

True or False: The scientific method is a cycle rather than

a list of steps.

$600

What is a hypothesis?

A testable explanation or predication

$800

Quantitative and qualitative

Two types of data you can gather.

$1000

Your research has been reviewed and accepted by other scientists.

What does it mean to be “peer reviewed”?

$200

Manipulated variable

The independent variable can also be called what?

$400

Responding variable

The dependent variable can also be called what?

$600

Provide baseline for data, comparison

What is the purpose of the control group?

$800

The group being exposed to the experiment

What is the experimental group in an experiment?

$1000

Things that remain the same in the lab

What are controlled variables? (constants)

$200

To describe what the graph is representing.

What is the purpose of the title for a graph?

$400

X axis

What axis does the manipulated variable go on?

$600

Y axis

What axis does the dependent variable go on?

$800

What type of graph best represents the data?

$1000

A visual representation of the data, shows trends in the data

What is the purpose of a graph?

$200

Resting heart rate

In the Heart rate lab what was the control group?

$400

What was the manipulated variable in the heart rate lab.

activity

$600

Time, activity, trials, location, how you check your heart rate, etc.

Give 3 controlled variables from the heart rate lab

$800

Heart rate after activity

What was the dependent variable in the heart rate lab?

$1000

What would be an example of a “good” testable question for

the heart rate lab?

“what are the effects of standing, jogging and holding your breath on your heart rate?”

$200

Daphnia Heart Rate Before being exposed to substances

In the Daphnia Lab what was the control group?

$400

The substance being exposed to the daphnia

In the daphnia lab, what was the independent variable?

$600

Heart rate after exposure

In the daphnia lab what was the responding variable?

$800

Any data with a number

Give an example of quantitative data you could

have gathered from the daphnia lab.

$1000

Any observation that involves the senses (no numbers)

Give an example of qualitative data you could

have gathered from the daphnia lab.
