100
The habit of watching and noticing what is going on in our universe.
observation
100
We use the scientific method to answer which types of questions?
testable (we can do experiments to determine possible answers)
100
Give 2 variables that could affect how well a student performs on a test
Many options
100
What were the independent variables in our coin lab?
different coins
100
What are 5 things we use when make an observation?
sight sound smell taste touch
200
A system for answering scientific questions.
scientific method
200
How do scientist figure out possible solutions to their questions?
They conduct experiments

We are studying two groups of bean plants to see how caffeine affects their growth. Everyday we give one group of plants water and the other group is given coffee. We measure the plants each week to see how they are growing. What is the control (constant) in this experiment?
Same bean plants
200
What was the dependent variable in our coin lab?
number of drops of water
200
Can the scientific method be used in any order?
yes, often times we will use a specific order in class, but scientist go out of order all the time.
300
An educated prediction that could be a possible solution to a scientific problem.
hypothesis
300
What is the format that we use to write a hypothesis?
We use if..., then... statements

We are studying two groups of bean plants to see how caffeine affects their growth. Everyday we give one group of plants water and the other group is given coffee. We measure the plants each week to see how they are growing. What are the independent variables in the experiment?
water/ coffee
300
In our Lifesaver lab. We collected information about the guesses of flavors of the Lifesaver candy. What do we call the chart that we wrote the information on?
data table
300
What should a scientist do if he wants to get valid and accurate results from an experiment.
Conduct the experiment several times.
400
The part of an experiment that is measured.
dependent variable
400
After conducting an experiment, we write a conclusion based on the data we collected, we also refer back to______________ to see if we were correct.
hypothesis

Mr. Owl wants to know how many licks it takes to get to the center of a tootsie pop (NO! NOT 9,0000). He decides to conduct an experiment to determine the answer. He gives 1,000 6th grade students a cherry tootsie pop and has them count the number of licks it takes them to reach the center. What is the dependent variable in this experiment?
number of licks it takes to get to the center of a tootsie pop.
400
During our coin lab we got a lot of different answers to the question, "How many drops of water will each coin hold." What could we do to get the most accurate data results? Hint-I am not looking for eliminate variables.
Conduct the experiment more times. The more you conduct the same experiment and get close results the more accurate your data is.
400
what is the purpose of using the scientific method?
To answer questions we have about the world we live in.
500
The part of the experiment that is changed on purpose
independent variable
500
What are the 6 steps of the scientific method, that we learned in class (there are more than 6, but we focus on 6).
Make an observation/Ask a question Make a hypothesis Conduct an experiment Collect data Write a conclusion Communicate the results
500
Give an example of an independent variable.
Answers will vary
500
The question we wanted to answer during our coin lab was, "How does surface area affect the number of drops of water a coin can hold?" Please state a proper hypothesis for this question.
Answers will vary-must use an if..., then... statement
