Why is it important to have several trials in an experiment?
To ensure results are consistent
What are observations in an experiment?
What you hear, see, smell, feel, and taste during the lab
When doing a lab, name one part of the lab
purpose
hypothesis
materials
procedure
observations
results conclusion
What are the three types of variables in an experiment?
control, dependent, independent
List 2 ways that we collected data during our labs
measured length of gummy bears
counted drops of water
measured distance planes travelled
hypothesis
Marcos thinks, "If plans are given 8mL of water and sunshine daily, then they will have the best growing conditions." What step of the scientific method is this?
Hypothesis
Why is the control group important
It allows us to compare our results to what might happen normally
The group that is not tested or changed in an experiment is called the _______ group. This is the "normal" group.
Control
Two sets of plants. One is watered, and one is not. What type of variable is the water?
Independent Variable
What is the first step of the scientific method?
Ask a question!
What is the procedure?
A step by step guide to what you need to do in a experiment
What is a hypothesis
an educated guess
Bar graph
Pie chart
Line graph
There are two types of fuel poured into the same car to see which one works best. What type of variable is the fuel?
Independent Variable
What is an independent variable?
What is manipulated or changed in the experiment
This is the variable that is measured in an experiment.
dependent variable
Give an example of a dependent variable from one of the labs we did
length of gummy bear
# of drops on a penny
how far the plane flew
What makes a testable question?
It needs to be specific, have a variable, and it needs to be able to be measured and observed
What are the 7 steps of the scientific method?
Ask a question, develop a hypothesis, research, conduct an experiment, collect data, analyze data, write a conclusion
Give an example of a controlled variable from the labs we did
same penny
same thrower, counter, in plane
amount of water, amount of solvent
Make a hypothesis for this testable question
How does increasing the slope of a ramp effect how far a marble travels?
If we increase the slope of a ramp then the marble will travel farther because slopes add more energy to the object that is traveling down it
Make a hypothesis for this testable question...
Will using liquid fertilizer make grass grow greener than granulated fertilizer
If we change the types of fertilizer then the grass will grow greener with the liquid fertilizer because liquid fertilizer absorbs faster
Find the variable in this testable question
Will using liquid fertilizer make grass grow greener than granulated fertilizer?
(Independent, dependent, control)
Independent: type of fertilizer
Dependent: grass growing
Control: the amount of fertilizer, amount of grass, location of grass
What is the difference between QUALITATIVE and QUATATAIVE DATA
Qualitative- observed with your senses
Quantitative - measured, counted, or calculated
