$100 Metric & Density
If the formula for density is mass dividedBy volume, what is the density of an objectWith a mass of 10 grams and a volumeOf 5 ml?
$100 Metric & Density
2 g/ml
$200 Metric & Density
If you place an object in a container And measure how much water is Displaced, what property are youmeasuring? Mass? volume? Density? Length?
$200 Metric & Density
Volume
$300 Metric & Density

$100 Scientific MethodWrite An appropriate HypothesisFor what willHappen afterThis experimentIs done?
$100 Scientific Method
If the metal ball is heated,Then the ball will expand and notFit through the ring
$200 Scientific Method
If you wanted to test the affect heat has on the dissolvingRate of a sugar cube, identify one variable you wouldWant to keep constant?
$200 Scientific Method
Amount of sugarAmount of waterType of heating device
$300 Scientific Method
Name oneObservation That you can makeBase on this diagram?
$300 Scientific Method
The ball is being heatedThe ball fits through the ring
$400 Scientific Method
Why would having more than one variable in an experiment different result in an unfair experiment?
$400 Scientific Method
Then you would not know which variable was causing the changes and could not compare variables against each other?
$500 Scientific MethodA student completes an experiment to test the effects of light on the growth of mold on bread? What error did the student make?
Day one Day Two
Temperature: 10°c Temperature: 20°cNo light light
$500 Scientific Method
Did not keep the temperaturesconstant

Increase temperatureStir solutionAdd more solventReduce the amount of solute
$200 Mixtures & SolutionsPhase changes
What happens during the processOf condensation
$200 Mixtures & SolutionsPhase changes
Water vapor becomes liquid water
$300 Mixtures & Solutionsphase changes
Above what temperature Is water in a gas form and what Is it called?
$300 Mixtures & Solutions
100°c and its called water vapor
$400 Mixtures & Solutionsphase changes
What phase change is occurring when water is boiling in a pan?
$400 Mixtures & Solutionsphase changes
Liquid to vapor
$500 Mixtures & Solutions
What phase change is occurring whenWhat phase change is occurring whenIce cubes are heated in a pan?Ice cubes are heated in a pan?
$500 Mixtures & Solutions
Melting – solid to liquid
$100 Matter & Periodic Table

$100 Matter & Periodic Table
Atomic number
$200 Matter & Periodic Table
Using the periodic table, what elementHas an atomic number of one?
$200 Matter & Periodic Table
hydrogen
$300 Matter & Periodic Table
which one is not an element? Why?
H HCL?
$300 Matter & Periodic Table
HCL because it has more thanOne element and therefore is A compound.
