The independent variable
The first stage of technological design
What is identify the problem
Water is
What is polar
The macromolecule who's main function is for short-term energy storage
What is carbohydrate?
Water loving
What is hydrophilic
The dependent variable
What is the effect or measured variable
The application of scientific discoveries to meet human needs or wants through development of products or processes.
What is technology
The smallest part of an element that still has the same properties of the element.
What is atom?
Small units that form together to make larger molecules
What is monomer?
Water fearing
What is hydrophobic
The second stage of technological design
What is design a solution
The six elements necessary for life
What are carbon, hydrogen, oxygen, nitrogen, phosphorous, and sulfur?
Macromolecule that contributes to the cell membrane
What is lipid?
A molecule with an unequal distribution of charge that CAN dissolve in water
What is a polar molecule?
A guess about an object or outcome based on oberservations
What is an inference
The third stage of technological design
What is implement (build and test)
What is tissue?
The order in which our bodies break down macromolecules
What are carbohydrates, lipids, proteins, NEVER nucleic acids
A molecule with no distribution of charge that cannot dissolve in water
What is nonpolar?
How close your measurement is to the correct/accepted value
What is accurate
The fourth stage of technological design
What is evaluate (did I meet the requirements/constraints)
Strong bonds that hold the water molecules together internally
What is covalent bond?
Three elements that are present in all classes of macromolecules.
What is carbon, hydrogen, and oxygen?
Two layers that make up the cell membrane of our cells
What is the phospholipid bilayer?
