The Process
This is the first step of the scientific method
What is question or problem?
This is the one thing that is changed in an investigation.
What is an (independent) variable?
TRUE OR FALSE: Fair experiments have multiple trials.
TRUE
This measures temperature
What is a thermometer?
HYPOTHESIS: If we change the depth of water, then the temperature of the water will increase.
What would be the problem or question of this investigation?
Does the depth of water affect water temperature?
This is an educated guess
What is hypothesis?
This is the variable that is measured in an investigation.
What is the dependent variable?
This is the number of variables, or things you should change in an investigation.
What is one?
This tool keeps your eyes safe while conducting an investigation
What are goggles?
This is a step by step process that allows scientists to solve problems and answer questions
What is the scientific method?
Scientist use data at the end of the scientific method to do this
What is make a conclusion?
These are all the other variables that stay the same in an investigation.
What is a controlled variable?
Scientists do this in an investigation to collect more data points, making sure their investigation is fair.
What are repeated (or multiple) trials?
This tool measures the mass of an object
What is a scale?
QUESTION: How will the height of a ramp affect the distance a car travels?
What is the independent variable of this experiment?(one thing changed)
The height of the ramp
These are the measurements that are written down as an experiment happens
What is data?
Tina and Roy want to see if if black paper or white paper will warm up in the sun quicker. This is the variable that they will change in their experiment.
What is the color of paper?
QUESTION: Does water temperature or size of the pot affect the boiling point of water?
Is this a fair question for a science investigation? Explain your reasoning.
No this is not a fair question. There are 2 variables to be changed in this question (water temperature and size of pot). You should test only one variable at a time.
This tool measures the volume of a liquid
What is a graduated cylinder?
Tina and Roy tested the temperature on white paper vs. black paper. Here are their results.
Minute White Paper Black Paper
1 78 degrees 78 degrees
2 79 degrees 80 degrees
3 79 degrees 81 degrees
4 80 degrees 83 degrees
What would be a good conclusion for this data?
The black paper got warmer quicker than the white paper.
In this experiment step of the scientific method, scientists communicate clearly so that other scientists might be able to repeat, or do the same investigation over again. (These are the things scientists write to communicate their process clearly.)
What is writing down all the steps and materials?
Tina and Roy want to see if if black paper or white paper will warm up in the sun quicker. These are examples of controlled variables they will keep constant in their investigation.
What are: same type of paper, same size of paper, paper in same location, measure temperature at same time
(Other examples may also be included)
Trial 1 = 50 meters
Is this a fair experiment? Explain your reasoning.
No, this is not a fair experiment. There is only one trial. There should be multiple trials to make sure the numbers are accurate and the experiment is fair.
This tool allows you to see small objects closer
What is a hand lens?
Juan wants to conduct an experiment. His question is: Do strawberry, spearmint and peppermint flavored bubble gum all make the same size bubble?
What data will Juan collect during this experiment?
What is the size of bubbles for strawberry, spearmint, and peppermint gum?
