FTCE K 6 UPDATED PAPER FINAL EXAM QUESTIONS AND
SOLUTIONS GUARANTEE A+
✔✔6 steps of any scientific method - ✔✔1 ask a question 2 make observations 3
hypothesize 4 predict 5 test 6 conclude
✔✔Observations - ✔✔are needed to answer scientific questions and may include
collecting observed data.
✔✔hypothesis - ✔✔a possible answer to a question not based on blind guessing, but
what is observed and testable.
✔✔Controlled experiments - ✔✔designed so that there is an experimental group and
controlled group.
✔✔variable - ✔✔Experimenta group and controlled group are identical except for one
factor, the _______.
✔✔variable - ✔✔is used in the experimental group.
✔✔Hair - ✔✔What should you tie back when conducting science experiments?
✔✔Safety goggles - ✔✔What can not be shared among students without sanitizing?
✔✔Fire extinguisher - ✔✔must be in the classroom not just in an adjacent classroom.
✔✔Required safety equipment - ✔✔eyewash stations, shower statrions, emergency
blanketss, first aid kits and fire extinguishers
✔✔Hazardous chemicals should be stored - ✔✔in locked cabinets that are low to the
ground.
✔✔Physical properties of matter - ✔✔mass, volume, density, physical change and
chemical change.
✔✔Matter - ✔✔is what makes up everything in the world: rocks people chairs building
water oxygen animals and chemical substances.
✔✔It takes up space(volume) and has mass - ✔✔matter
✔✔volume - ✔✔takes up space. amount of cubic space that an object occupies
✔✔matter - ✔✔involves molecules and atoms, but also subatomic particles.
, ✔✔subatomic particles - ✔✔protons, neutrons and electrons.
✔✔Mass of an object - ✔✔is always the same and is independent of gravity
✔✔gravity - ✔✔an attractive force that draws objects towrd the center of the earth.
✔✔weight - ✔✔_____ is often confused with mass.
✔✔Weight - ✔✔The measure of the earth's pull of gravity on an object.
✔✔Density - ✔✔is defined as mass per unit of volume or the ratio of total mass to total
volume. p=m/v
✔✔density - ✔✔How closely the molecules are packed together and depends on the
type of matter used but not the amount of matter.
✔✔sink - ✔✔An object is more dense than the liquid that surronds it will _______
✔✔examples of chemical changes - ✔✔burning, rusting, and digestion
✔✔broken glass - ✔✔example of physical change
✔✔physical change - ✔✔does not produce a new substance
✔✔chemical change or reaction - ✔✔does produce one or more substances
✔✔Classification of matter - ✔✔involves elements, compounds, mixtures and solutions.
✔✔Element - ✔✔a substnace that consists of only one type of atom and is represented
by a symbol consisting of one or more leltters.
✔✔An element - ✔✔cannot be broken down into other substances of that element.
✔✔Elements - ✔✔oxygen (O), iron (Fe), and carbon (C)
✔✔atom - ✔✔smallest particle of the element and is the basic building block of matter.
✔✔gas - ✔✔It has no definite volume and takes the shape of the container. Has
relatively low density and viscosity, which distinguishes it from liquid and solid.
✔✔examples of gas - ✔✔water vapor or steam
