What is the goal of science
To find and understand knowledge, become more curious. Things in science often start with curiosity, and end with discovery.
Explain how science and technology are related.
They are interdependent. Advances in one lead to advances in the other.
List the major branches of natural science and describe how they overlap.
Life earth and physical. There is life/living things on the earth. and physical science talks about how the earth and things on the earth move, and what they are made of.
Describe the big ideas of physical science
Space and Time: Observable universe is 700 million billion billion miles. The earth is about 9000 years old
Matter and Change: Most of the universe is empty, Earth has matter, which is made of atoms.
Forces and Motion: Push/pull causes change in motion
Energy: Both chemistry and physics, kinetic and potential energy
Describe the mindset of a Christian Sceintist
to learn about God’s creation, and how to take care of it.
Describe the steps in a scientific method
Ask a question, do background research, hypothesis, Test your hypothesis, analyze data, if your hypothesis supports your hypothesis, then retest to confirm your results. If it does not support your hypothesis, then you go back to your hypothesis, and find out what you did incorrectly. Once you find all of your conclusions, you publish your results.
Describe how scientists test a hypothesis
After a scientist sets their criteria, they have a controlled experiment, changing one variable at a time. Then, they start their experiment with their manipulated variable. And their responding variable. After they test, they look at their data and conclude whether they need to retest to confirm, their hypothesis, or if they need to go back and change their hypothesis.
Identify ways in which a scientific claim is evaluated (e.g. through scientific argumentation, critical and logical thinking and consideration of alternative explanations.)
Many times after an experiment is published, other times many scientists will retest what the original scientist found. Once they finish their research. They will either similarly conclude, or they will inform the other scientist of their findings, or will argue it.
Identify the criteria needed for a controlled experiment.
During a controlled experiment, only one variable is changed per trial. Those trials are then analyzed and conclusions are made.
Compare and contrast facts, scientific theories & scientific laws
A scientific law describes an observation based on a pattern. An explanation is provided by a scientific theory. A fact is something that is/can be proven by a scientific theory or law.
Explain and implement safety procedures for the science classroom.
If glass is dropped, use a broom to sweep up shards, and put them into the “glass” bin. Always wear goggles and closed-toed shoes during labs. If there is a gas leak, turn off the gas using the emergency shut-off button near the door. If you get chemicals in your eyes or near them, use the eye wash to rinse them out.
Identify the metric and SI units used in science and convert using the base unit and common metric perfixes. (kilo, deci, deca, centi, milli, hecto)
Kilo- 1000 units = 1 kilo Hecto- 100 units = 1 hecto Deca- 10 units = 1 deca Unit - meter, liter, gram. Deci - 1 unit = 10 decis Centi - 1 unit = 100 centis milli - 1 unit = 1000 millis
Calculate the slope of a straight line on a graph
rise/run
Identify the relationship between a manipulated variable and a responding variable.
The manipulated variable that you want to change. The responding variable is what changes based of what you did.
Explain the importance of communicating data.
If you even mess up 0.01 digit, it completely changes the number. It also helps people learn from what you did.
