Vocabulary
A measuring tool connected to computers that helps analyze and interpret data.
What is probewear?
Three main branches of science that have a bunch of related things intertwined between them.
What is life, earth, and physical science?
A system of units that is used worldwide by scientists that was originally created by France.
What is the International System of Units (SI)?
Laws say what happens, while theories say why it happens. Laws usually stay the same while theories constantly change.
What is the difference between laws and theories?
Scientists will use models to represent or simulate something that may be difficult to understand in words alone. This way it makes communication much simpler and easier.
It includes observations/measurements that people gather and test to evaluate scientific claims. It helps scientists by giving clear-cut evidence to communicate across the world.
How does empirical evidence help scientists?
1. The pyramids were built by aliens vs. the sky is blue because there are tiny blue bugs flying above.
2. Because you can't prove my computer isn't a time travel device, it's a time travel device vs. instant noodles have a bunch of unhealthy stuff in it. (totally not true, I eat it all the time))
What are a few examples of how pseudoscience differs from science?
a * 10^b
How do you write in scientific notation?
There are new pieces of evidence being discovered constantly. Our scientific explanations are always just the best explanation for a process of nature, with new evidence being discovered, they change too.
What is an example of how scientific ideas change?
Scientists may use current and previous patterns to simulate a complete model of, for example, what the weather will be like for the next few days, weeks, or even months.
How do scientists use models to make predictions?
A well-supported explanation of nature that also explains laws.
They provide a description for processes of nature that is based on evidence (observations and data).
What are the advantages of using a common system?
Laws describe mainly the principles of nature.
What does a law mainly describe?
They are used to estimate distance, volume, and quantity.
What are scale models?
A description of a specific relationship under given conditions in the natural world.
Making observations with your senses and contributions, using curiosity (asking why and how), and using creativity (originality and applying imaginations) will get you _______.
How do you get involved in scientific work?
Scientists may use hot plates, test tubes, racks, journals, technologies (computers and probewear), and notebooks. Pencils count too!
What are some tools that scientists may use in investigations?
Using the force of gravity as an example, explain what the law and theory is.
What are some advantages of physical models?
A deliberately changed factor in a controlled experiment.
What is an independent/manipulated variable?
Because communicating scientific ideas are so important, once one scientific idea is communicated, it will gradually spread around the whole world.
How does science get communicated across the world?
Liters
What is the unit that is used for volume but not an SI unit?
The Kinetic Theory of Gases states that pressure increases as a gas continually bounces around.
What is an example of a theory?
Physical models may not behave or act like the real thing, since physical models may not be tested in its original environment.
What are the disadvantages of physical models?
