Which step of the scientific method is missing: Question. Research. Formulate a Hypothesis. ______________. Observe and Record. Analyze Results. Share the Results
What is Experiment
What is one way to visualize your data/results?
What is Make a graph or table
What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...Independent-soil temperatures, Dependent-plant growth.
If soil temperatures rise, then plant growth will increase. What is the dependent variable?
What is plant growth
A hypothesis should be written in what format?
What is "If.... Then..."
What is the variable that changes as a result of the experiment? (the one you are observing)
What is dependent variable
How doe temperature of a liquid affect how fast sugar dissolves in it? Identify independent and dependent variables
Independent: Temperature of liquid
Dependent: how fast the sugar dissolves
I observe that sugar dissolves faster in my hot chocolate than it does in milk. What is a testable question for this observation?
Does the temperature of the liquid affect how fast the sugar dissolves?
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones.
What is the variable you are changing on purpose?
What is independent variable
What is the purpose of a control group?
To see if the independent variable had any impact on the experimental group. For comparison.
How doe temperature of a liquid affect how fast sugar dissolves in it? Write a hypothesis for this question.
What is If I put sugar in a hot liquid, then the sugar will dissolve faster than it would in a cold liquid.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a control in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.
In an experiment what are the variables that are not being studied that stay the same so that they do not influence the experimental outcome called?
Constants/Controls
List all seven steps of the scientific method.
What is Question, Research, Hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
If I increase the amount of time I run, then my heartbeat will increase. What are the independent and dependent variables?
Independent: amount of time I run
Dependent: heart rate
Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
What is...If I increase the amount of time I run, then my heartbeat will increase.
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is Independent- practice shooting free throws, Dependent- making baskets.
