Role of a Scientist
What is a hypothesis?
A hypothesis is an educated guess based off of what the scientist has observed or researched.
What does it mean to infer?
Infer refers to the process of thinking about observations.
Scientists will do research before they experiment. What are ways in which scientists can research?
Examples: read a book, email a scientist, visit a museum, read an article, search science websites.
A drawing or a map is what type of model?
A 2-dimensional (2D) model uses length and width. Examples of 2D models are drawings or maps.
What is the best way to communicate data to an audience?
A scientist might use a graph or chart or drawing to communicate information to an audience of their data.
When a scientist collects information using their five senses, what is the scientist doing?
The scientist is making an observation when they gather information using their five senses.
Scientists will sometimes share their results and inferences with other scientists. What is this process called?
It is called communication when the scientists share their information with other scientists.
What is the tool that a scientist will use when they need to see something that cannot be seen with the eye alone?
A microscope is used to see things that cannot be seen by the eye alone.
Scientists will use a 3D model for what reason?
A scientist will use a 3D model to make an object smaller to scale to experience the real thing.
When a scientist watches a group of people interact and records the information, this process is called what?
The scientist is organizing their data.
What does a scientist study?
A scientist studies the natural world.
When scientists use their data to determine specific result that has not happened yet, this is called what?
Scientists are using the process called prediction when they use their data to determine what will happen next.
What tool will a scientist use if they want to measure the temperature?
A scientist will use a thermometer to measure the temperature.
A scientist will model their data on paper using numbers. This is called what?
Scientists will use charts and graphs to model data using papers and numbers.
Scientists study the natural world. Evidence is an important part of their studies. What is evidence?
Evidence is data that supports or rejects a hypothesis.
What is the next step after a scientist gains their evidence?
A scientist will then draw conclusions after they have obtained evidence.
Scientists will use several items in their experiments. These items are called what?
The different items in an experiment are called variables.
If a scientist wants to measure the mass of an object, what tool will they use?
A scientist will use a pan balance to measure the mass of an object.
What type of model is used to experience a real object or real event through motion?
A scientist will use a computer model to experience a real object or even through motion.
Give an example of a 3D model.
Examples include: a plastic model of the solar system, a clay model of a skull, a play dough model of a flower.
When something is observed in the natural world, the first step is to _____________.
The first step is to ask questions about the natural world.
This process is called classifying and ordering.
What tool is used by a scientist when they want to measure the amount of force that is used?
A scientist will use a spring scale to measure force
What type of model is used to save lives through sending pictures back to Earth?
A weather satellite is used to take images of Earth and can save lives by predicting the future weather.
A scientist wants to find out which is the best food for a dog. What variable could the scientist use in the investigation?
A scientist would use different types of dog food and a hungry dog.
