100
An educated guess about how things work.
What is a hypothesis?
100
Can be answered through investigations (must be measurable).
What is a testable question?
100
Name the first two steps of the scientific method.
What is, 1) Ask a testable question and 2) Form a hypothesis.
100
You are trying to see if different brands of light bulbs last longer than others. Write a testable question.
What is "Does changing the brand of light bulbs affect the time it takes to burn out?"
100
The x-axis will always be your _______ variable.
What is the independent variable?
200
What is changed in an experiment.
What is an independent variable?
200
What is measured in an experiment.
What is dependent variable?
200
Name the last step of the scientific method.
What is, 6) Write a conclusion.
200
You are trying to see if different brands of light bulbs last longer than others. Write a hypothesis to this experiment.
What is "If changing the brand of light bulb affects the time it takes to burn out then BRIGHT will last the longest while SPARKLE will last the shortest."
200
The y-axis will always be your _______ variable.
What is dependent variable?
300
An experiment that is fair among all variables except the independent variable.
What is a fair test?
300
An observation made using numbers.
What is quantitative variable?
300
Name the third step of the scientific method.
What is, 3) Plan the procedure and gather materials.
300
You are trying to see if different brands of light bulbs last longer than others. Name the independent, dependent, and controls of this experiment.
What is "independent- different brands of light bulbs; dependent- how long the light bulbs last; controls- same watts, same type of lamp, same temperature in the room, etc."
300
You are seeing how the mass of different tennis balls affect the distance that it travels. Name the title of a graph that you would use for this experiment.
What is "The Mass of Tennis Balls vs. Distance."
400
A conclusion based on your observation.
What is an inference?
400
An observation made using your senses.
What is qualitative observation?
400
Name the fourth step of the scientific method.
What is, 4) Conduct an investigation to gather data.
400
Your best friend CooCoo says that Skittles dissolve faster than M&M's. You decide to test it out yourself. You test one green Skittle and one green M&M. You are happy to find our CooCoo was right. Is this a fair test? Why?
What is "This is not a fair test because your finding are bias. It is also not a fair test because you only tested this experiment one time and not three times."
400
How can you tell when you are going to graph a bar graph or a line graph.
What is, a line graph will have numbers for both the independent and dependent variables?
500
Looking closely at something using the 5 senses.
What is an observation?
500
The things in an experiment that stay the same.
What is a control variable?
500
Name the fifth step of the scientific method.
What is, 5) Record and interpret data.
500
You are trying to see if different brands of light bulbs last longer than others. Your hypothesis states that BRIGHT will last the longest and SPARKLE will last the shortest amount of time. You conduct an experiment and gather the following information- LIGHT- 4 hours, SPARKLE- 6 hours, BRIGHT-5.5 hours, and STAR- 7 hours. Write a conclusion for this experiment.
What is "my hypothesis was rejected because the brand STAR lasted the longest while the brand LIGHT lasted the shortest time. For example, STAR lasted seven hours while LIGHT lasted four hours. I can conclude that the brand STAR will be the best buy because it lasts longer than other brands."
500
You are seeing how the mass of different tennis balls affect the distance that it travels. Name the x- and y-axis.
What is x-axis- mass of tennis balls; y-axis- distance the tennis balls travel?
