The Steps in Order
The FIRST Step, where you use your senses to notices something in the world.
Observation
A testable, educated guess that answers your questions.
A hypothesis
Maria notices that plans by the window are taller than the ones in the closet. Which step?
Observation
True or False: a hypothesis is just a wild guess with no thing behind it.
False - it is an educated guess.
The tool you use to observe things too tiny to see with your eyes, like cells.
A microscope
After an observation, this is the thing you start to wonder about.
A question
An experiment.
Maria wonders, "Do plants need sunlight to grow tall?" Which step?
Asking a question
A good hypothesis is often written using these two connecting words.
"If...the..."
The tool that helps you observe small things up close, like a bug or a left. Or to make sunlight stronger.
A magnifying glass.
Put these three in the correct order: experiment, hypothesis, question.
Question->Hypothesis->Experiment
The facts, numbers, and measurements you collect during an experiment?
Data
Maria writes, "If plants get sunlight, then they will grow taller." Which step?
Hypothesis
Finish a hypothesis, "If I water a plan with soda instead of water, then____
The plant will grow slower or slowly.
Why do scientist repeat an experiment more than once?
To make sure the results are correct and not an accident.
The Steps right AFTER the experiment, where you decide what your results mean.
Draw a conclusion
Sharing your results with others through a poster, chart, or report.
Reporting (communicating) your results.
Experiment
True or False. If the experiment shows your hypothesis was wrong, you failed.
False - a wrong hypothesis still teaches you something; that is good science.
The name for the whole step-by-step cycle scientist use to answer questions?
The Scientific Method
Name all 6 steps in the scientific method in order.
Observation, question, hypothesis, experiment, draw a conclusion, report results.
The one thing you change on purpose in an experiment?
The variables
Maria studies her measurements, decides sunlight helped, and makes a poster for class. Which TWO steps?
Drew a conclusion AND report results
Explain WHY a hypothesis much be testable."
Because you must be able to run an experiment to check if it is true or false.
A scientist's conclusion does NOT match their hypothesis. Name TWO things they could next.
Try a new hypothesis (run it again) or test a new question or change one variable.
