Nature of Science Vocab
The "HOW" - describes patterns in nature
What is a Law
attraction between molecules of the same substance
What is cohesion
Monosaccharides, Polysaccharides, 4cal/g, short term energy storage, in sugars and starches
What is a carbohydrate
goggles, apron, gloves
What is safety gear
Name of the curved line of a liquid in a graduated cylinder
what is a meniscus
the "WHY" - an explanation of an observed phenomenon
What is a theory
type of attraction that happens between different molecules - stronger than cohesion
What is adhesion
fatty acids, triglycerides, 9cal/g, long-term energy storage, found in fats, oils, and steroids
What is a lipid
Proper way to smell a chemical
what is wafting
The most precise measurement between 10ml and 13.5ml
13.5ml
description of something using your senses
What is an observation
regulates temperature in cells, allows life to live in water, keeps earth's climate moderate
what is specific high heat of water
Amino acids, polypeptides, 4cal/g, many functions, found in meat, nuts, and dairy - also your body makes them
What is a protein
What you do if you break glassware
Tell teacher
Unit to measure mass
grams
What the experimenter will deliberately change or manipulate in the investigation
What is the independent variable
Water is Polar or Nonpolar
What is polar
Tell me about Nucleic Acids
Nucleotides, Nucleic Acid (DNA/RNA), 0cal/g, Found in DNA (you get them from your parents)
First thing you do in an experiment
Read the directions
Part of microscope you put a slide on
The stage
What changes in response to the independent variable - what is measured
What is the dependent variable
The property of water that allows life to exist under frozen surfaces of lakes/polar seas
What is density as a solid
2 fatty acids + a phosphate, hydrophilic head, hydrophobic tail, creates the phospholipid bilayer
What is a phospholipid
There's a fire!
Tell teacher, if it is an object (fire extinguisher), if it is a person (fire blanket/drop and roll)
The focus you use when using the highest objective lens
Fine focus
