$200 meter The metric unit used to measure length

$400 gram The metric unit used to measure weight.

$600 liter The metric unit used to measure volume

$800 1 ml How many milliliters are in 1cm 3

$ ,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.
