Scientific Investigations
An educated guess
What is a hypothesis?
The amount of matter in an object
What is mass?
Creativity, methodical thinking, usage of math and models, usage of science, and usage of technology
What are skills that scientists need?
A triple beam balance
What is used to measure mass?
First step to Scientific Inquiry
What is observation?
The amount of space an object takes up
What is volume?
Technology that is basic, inexpensive and does not have technology
What is simple technology?
If a person's mass on Earth is 26 kilograms, what is their mass in deep space
What is 26 kilograms?
A variable deliberately changed by a scientist
What is an Independent variable?
The amount of mass per cubic centimeter
What is density?
The first step of the Engineering Design Process
What is identifying a need?
The formula for density
What is mass divided by volume?
A part of an experiment that doesn't change
What is a control?
The amount of gravitational pull on an object
What is weight?
A working model of the invention
What is a prototype?
Scientists observe, form a hypothesis, come up with an experiment, record data, and analyze it to come up with a conclusion
How do scientists discover things?
A variable that is changed because of the independent variable
what is a dependent variable?
An object's mass is less than the weight
What is floating?
Getting one advantage while giving up another
What is a trade off?
Grams/ cubic centimeter
What is the unit to measure density?
