Question | Answer |
Problem | The question a scientist asks |
Hypothesis | An educated guess about the outcome in a controlled study |
Manipulated(change) Variable
(Independent Variable) | The "one" Variable that changes in a controlled study |
Dependent Variable | What is being measured in the controlled study. |
Controlled(constant) Variables | The variables that remain exactly the same in a controlled study. There should be many of these variables. |
Procedure | The steps listing the process of conducting a controlled study |
Materials | The objects/resources needed to conduct a controlled study. |
Observations | The "results" or "measurements" that can be witnessed using the senses(eyes, ears, smell, taste, hearing) |
Data | The information that can be gathered in a controlled study |
Conclusion | The final thoughts of a controlled study. It answers the Hypothesis |
Further Study | Additional research or additional studies that can be performed that have a connection to the controlled study that was just completed. |
The Scientific Method | Five Steps |
Step 1: Problem | State the problem and develop a hypothesis |
Step 2: Plan | Plan the experiment by developing a procedure. |
Step 3: Data | Gather data from the experiment. |
Step 4: Organize | Organize your data using tables, charts, and graphs. |
Step 5: Analyze and conclusion | Analyze the data and draw conclusions from the data |
To measure distance the unit is? | a Meter - M |
To measure mass(weight) the unit is? | a Gram - g |
To measure volume(how much) of a liquid there is? | a Liter - L |
A Meter is used to measure the size of your (room, toe) | A meter(m) is used to measure something the size of your room. From here to Lake George would be measured in kilo-meters |
A millimeter is used to measure the size of (your finger name, your room)? | A millimeter(mm) is used to measure small objects like the "thickness" of your finger nail. The length of a pencil is a centimeter(cm) |
A gram is used for the weight of an elephant or a fruit snack? | Fruit Snack. grams(g) are very small. Kilo-grams(kg) would be used to weigh an elephant |
