You cannot skip ahead to a specific page. Sorry!!!!Lab Equipment How we will play, is you will receive a picture of a piece of lab equipment and you are given the name or what it does. Then, you have to fill in the blank

What is this piece of equipment?This piece of equipment is used for calculating the weight or force of an object in Newton

SPRING SCALE!!A Triple Beam BalanceWhat is a triple beam balance used for???

A triple beam balance is used for measuring an objects mass (g)A Test TubeWhat is a test tube used for??

Holding small amounts of liquids or chemicalsWhat is this piece of lab equipment?It is used for holding and mixing liquids and chemicals.

FLASK!!!!!What is this piece of lab equipment?It is used for measuring length and height (cm).

RULER!!!!!A Graduated cylinderWhat is this lab equipment used for?

Measuring liquids (mL)What is this lab equipment?It is used for measuring and dispensing small amounts of liquid.

PIPETTE!!A Lab Scoop/ SpatulaWhat is it used for?

Scooping chemicals and powdersWhat is this lab equipment?It is used for holding or heating liquids.

BEAKER!!!A Test Tube TongsWhat is it used for???

Holding test tubesSection TermsThese are terms (bolded and colored words) from your textbook that were stated in the beginning of each section. Hope you payed attention.Physical ScienceThe study of matter and energy. It is split into two categories known as Physics and Chemistry.

Scientific MethodA series of steps that scientists use to answer questions and solve problems.

TheoryA unifying explanation for a broad range of hypotheses and observations that have been supported by testing.

TechnologyThe application of knowledge, tools, and materials, to solve, problems and accomplish tasks; technology can also refer to the objects used to accomplish tasks.

ObservationsAny use of the senses to gather information.

ModelA representation of an object or system.

LawA summary of many experimental results and observations; a law tells how things work.

DensityThe amount of matter in a given space; mass per unit volume.D=m/V

HypothesisA possible explanation or answer to a question.

AreaA measure of how much surface an object has.

MeterThe basic unit of length in the SI system. (m)

DataAny pieces of information acquired through experimentation.

VolumeThe amount of space that something occupies or the amount of space that something contains.

TemperatureA measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object.

MassThe amount of matter that something is made of.

Section 1Exploring Physical ScienceWhat did Czarnowski and Triantafyllou create? What part of nature inspired this idea?They created a boat known as the Proteus. It had two broad paddles and two car batteries. The Proteus was designed after a penguin and the paddles were suppose to move like the penguins flippers.What is physical science? What 2 categories split physical science?Physical science is the study of matter and energy.It is split into Physics and Chemistry.What purpose do models serve?To demonstrate an idea, event, or object. Represent an object or system.Business: graphs, tables, charts, etc.Students/ Teachers: demonstrations- atoms, space, particles, etc.Physics or ChemistryWhen you move right and your car is turning left.PhysicsPollution affecting the atmosphereChemistryRainbows after a rainstormPhysicsDirty clothes becoming cleanChemistryWhy water boils at 100 degrees Celsius ChemistryEnergy+ Matter= Physical Science p. 7What do a ball, air, and a cheetah have in common?They are made up of matter and they also have energy.Moving objects have energy. Do non-moving objects have energy?YesSection 2Using the Scientific MethodTrue or FalseAdvancements in science are mostly due to luck.FalseScientists usually ask a question before they make any observations.FalseScientific laws are determined by nature.TrueA scientific law is a summary of many experimental results and observations.TrueLaws tell you why something happens, not what happens.TrueYou could be arrested if you break a scientific law.FalseWhat is the Scientific Method?Scientist use the scientific method to.Ask questionsSolve problems by following a series of stepsHypothesisA hypothesis isUsually stated in an ifthen format

What is a hypothesis?A possible explanation or answer of a question

Analyzing, Conclusions, and Communicating ResultsAnalysis of results means doing what with the data?organizingWhat are 3 ways that communicating results can help other scientists further scientific research?Scientists can- based on your results- study a new problem, conduct their own test, or even try to learn something more specific by modifying your test. What is ALWAYS true for scientific investigations?Scientist take accurate measurements and accurately record data.Building Scientific KnowledgeAn idea that is supported by many tests and experiments can become what (2 things)?A theory or a law

What is NOT true about a scientific theory?It is a simple guess

Section 3Using Models in Physical ScienceTrue or FalseWhen we picture things in our minds, we are creating models.True

What did the MIT engineers hope to gain from making a model?They hoped to gain more knowledge and a greater understanding about a boats propulsion.What is a model?Something that can represent or .Systems or ObjectsWhat are some ways to use models in science?looking at the tiny parts of a microscopic cell on a cell diagram, testing a new design for a building on a computer before spending the money on construction, launching a homemade rocket in your backyard, observing how the parts of matter fit together without being able to see the tiny particles, etc.Models Help You Visualize InformationHow could using the spring toy as a model help you understand the behavior of sound waves?It helps you understand the behavior of sound waves because it shows particle will crowd together- form a group- in certain parts of the sound wave.Models are Just the Right Size/ Models Build Scientific KnowledgeModels can be used as to illustrate and investigations.Scientific ideas/objects, theories, conductObjectSmaller or LargerMount EverestSmallerA computer chipLargerThe moonSmallerA skyscraperSmallerA mosquitoLargerNow come up with 2 or 3 examples of when the model would be larger and when the model would be smaller.Models can Save Time and MoneyHow can cyber- crashes save time and money?It can save time because you can find out in the cyber- crash what part of the car should be fixed before building it and wasting money adding something thatll just be removed later.Section 4Measurement and Safety in Physical ScienceBeginning/ The International System of UnitsBefore you determine how many lenses will fit into a moving crate, what must you figure out? The volume of the crate and the volume of the lenses.At one time, systems of measurements were based on objects that varied in size, such as body parts and grains of barley. (true or false)TRUEScientist can and their data when data are expressed in SI units.Share and compareWhat unit of measurement is most practical for measuring a house?Meters (m)The is the SI unit for temperature, but scientist often use degrees Celsius.Kelvin (K)Derived QuantitiesWhat are the 2 kinds of derived quantities?Area and DensityDescriptionsSharp ObjectsHand SafetyAnimal SafetyPlant SafetyEye ProtectionChemical SafetyHeating SafetyElectrical SafetyClothing SafetyWhat image goes with each description.
