scientific method
This step involves collecting information and observations before conducting an experiment.
what is Research
researching the problem
what are the 3 states of matter
solid liquid and gas
the amount of matter in a given volume
density
which of these are considered matter.
apples
grapes
water
energy
apples, grapes, and water
This is an educated, testable prediction about what you think will happen in an experiment.
Hypothesis
All matter is made up of tiny particles called
atoms
if the objects density is greater than the density of the liquid it is in, the object will
sink
why is a balloon with air in it heavier than a balloon without air?
it has matter in it
Organized process to test the hypothesis
Experiment
what type of matter has a definite shape and volume
solids
knowing the relationship of mass to volume or density will help you determine whether or not and object will
_______________ or ____________________
sink or float
which of these is less dense than air?
Styrofoam, wood, or helium
helium
observations and measurements recorded
Data
liquids take the shape of their
container
what is the formula to find the volume of an object?
length x width x height
what is the property that tells us how well something dissolves
solubility
A judgement based on the results of an experiment
Conclusion
Whar are the three basic properties of matter?
shape mass and volume
find the volume of a 3 dimensional object with a height of 9cm width of 15cm and length of 7cm
945cm
what property makes plastic a good choice for a pot handle?
