Identify a problem or ask a question Complete research about your topic Form a hypothesis what you believe will happen Create a list of Materials Create a list of procedures in order (so you can retest) Begin Trials (testing your experiment more than 1 time) Record Data during and after each trial Results: when you write down what happened in your experiment with the data included (what happened) Conclusion: A summation of your experiment relating to your hypothesis and what you learned Application: How can you apply your experiment and what you learned to the real word.
3
Mrs. Wells builds a model using a pizza box and aluminum foil to prove her theory. Ms. Artuz wants to build the same model. What will she need to do? A. Share her hypothesis with her friend B. Make a bar graph of the data C. Conduct research about other models D. Communicate the procedures used.
4
The key words are “same model” To build the same model you must communicate the procedures
5
Data is the information that is gathered in an experiment or investigation. Daytona 500 RaceChase Elliott Jeff Gordon Time (in hours) 1 hour Distance (in miles) 196201 Who drove faster?
6
You have to look at the length of distance of each car using the same amount of time.

B.Gerry’s team chooses objects with less mass than objects chosen by any other team. C.Bill’s team chooses an object that is heavier than any other of the team’s objects. D.Sammy’s team chooses the lightest objects of all of the teams.

What can you infer Water Temp. © over time 0 Minutes 15 Minutes 30 Minutes 45 minutes Cold Water10141721 Room Temperature 21 Hot Water32292725 A.The cold water increased 7 degrees in 30 minutes B.The cold water gained heat energy, and the hot water lost heat energy C.The hot water decreased 5 degrees in 30 minutes D.It will take 75 minutes to cool the hot water to room temperature
10
An Inference is what you will believe will happen. A. and C are using specific numbers – this is called results. B is making a Conclusion D is inferring what will happen as time goes on.
11
Room is 30 degrees Room is 85 degrees Closed door What will happen when you open the door between the two rooms?
13
Room is 30 degrees Room is 85 degrees A.It helps me form a hypothesis B.It makes you record data after following the steps in the procedure. C.It helps me investigate temperature change without costing much
14
Matter – anything that takes up space 3 States of Matter: Solid, Liquid, Gas Properties of Matter Size – shape - volume Mass Texture Smell Taste
15
Two balls are put into two different but identical beakers that have the same of water. The pink ball raises the water higher than the yellow ball. How can you explain what happened?
17
200 grams 75 grams ?

20
Celsius temperature on the thermometer is 23 degrees 88 degrees less 23 is a difference of 65 degrees

A B D C
22
The poles are the strongest part of the magnet There are 2 poles – North and South A magnet will repel when the same poles are near each other: Examples
23
X A.An iron nail B.An aluminum can C.The north end of another bar magnet D.The south end of another bar magnet
24
The key is MOVE AWAY Remember magnets repel like poles
25
A.The water has physically changed the out layer of the iron to show rust B. The water has dissolved some of the iron creating a new substance called rust C. The water has cooled the iron and caused it to change into rust. D. The water has chemically changed the iron to form a new substance called rust.
26
Chemical change happens when you get a new substance and cannot get the old substance back Physical change is when you change an item but it is still the same item Let’s look at some examples
27
Physical ChangesChemical changes Tearing paperRusting metal Broken cutTarnish on metal Scrambling an eggBurning something Molding clayFrying an egg Mixing water and saltMixing baking soda and vinegar Making a paper airplane Cutting paper
28
A. Grilling vegetables B. Melting butter C. Frying Chicken D. Toasting garlic bread
29
I can heat butter to melt it, but if I let it cool… it is still butter
30
A. Mechanical B. Physical C. Chemical D. Phase
32
Heat Light Sound Mechanical Chemical Electrical
34
Chemical Electrical Sound mechanical Electrical Light heat Light heat mechanical Heat Light A stove does have sound and mechanical too
35
A. Heat energy from the air is evaporated by the ice cube B. Cold energy from the ice cube is transferred to my hands. C. Cold energy from the ice cube is absorbed into the warm air D. Heat energy from my hand is transferred to the ice cube causing it to melt.
37
A. Cold from the ice transfers to the hot chocolate B. Heat from the hot chocolate transfers to the ice cube C. Heat from the hot chocolate sinks to the bottom of the cup D. The hot chocolate does not let the cold escape from the ice.
38
Remember hot air rises and hot molecules move faster than cold molecules.
39
A. The water and the melted ice will be the same temperature B. The water from the melted ice will become warmer than the water that was in the glass at first C. The water from the melted ice will dissolve into the warmer water in the glass D. The water in the class will become as cold as the ice was before it melted.
40
Eventually after all the ice is melted the water and ice will become the same temperature
41
A. Foil B. Wood C. Plastic Wrap D. Wool blanket
42
Conductor allows heat or cold to transfer easily Metal, glass, foil Insulator protects (keeps out heat or cold) Styrofoam, wood, rubber, cork, air, fabric
43
A. The metal spoon stayed cooler than the wooden spoon B. Both spoons got hotter C. Both spoons made the soup colder D. The wooden spoon stayed cooler than the metal spoon.
44
Conductor allows heat or cold to transfer easily Metal, glass Insulator protects (keeps out heat or cold) Styrofoam, wood, rubber, cork, air
45
A. Heating up the air B. Absorbing energy from the air C. Releasing molecules in the air D. Vibrating in the air
46
Pitch is the how you describe if the sound is high or low. Sound comes in waves – the closer together the waves the higher the pitch The farther apart the waves the lower the pitch.
47
A. The pitch gets lower B. The pitch gets louder C. The pitch gets higher D. The pitch stays the same
49
A. The water makes sound B. The water conducts heat C. The water causes motion D. The water causes changes in the temperature.
51
If you roll a ball across the floor and your friend kicks it which direction will it go? Draw a diagram of you, the ball and the direction your friend is kicking it.
52
A B C D
54
A.The ball will change position and may change direction B.The ball will change direction before changing position C.The ball will always change position and direction D.The ball will change direction but not position
55
Position is its place from where it started The balls position changes as soon as they let go. It will change direction when it rolls off the table
56
A. distance B. direction C. position D. speed
57
Speed relates to time. The stop watch is the key
58
PersonTime it took from home to library You10 minutes Friend A18 minutes Friend B7 minutes A.The time each of you arrived at the library B.The time each of you left your house C.The distance from each of your houses to the library D.The distance between your houses.
