OBSERVATIONS
What do you call a statement based on the use of one or more of the 5 senses that CANNOT be assumed?
An observation
What are the three possible reasons we questions?
Clarification, Confusion, or Curiosity
What is research?
The process of gathering information about a topic
Your hypothesis should directly answer your _____-_______ _________
Open-ended question
What do you call a variable that has an effect on another variable whose value is also controlled by the experimenter?
Independent Variable
Every observation that anyone makes will always be _________
Factual / True
What is a question?
A type of sentence that prompts someone to think of or provide an answer
What is the general definition of mass?
The amount of "stuff" in an object
What is a hypothesis?
A statement one makes to provide a potential answer to the question being asked based on their research
What is an experiment?
An operation under specific conditions that is meant to test a hypothesis, demonstrate a known fact, or make a discovery
What are the 5 possible ways to observe something?
Sight, Hearing, Taste, Smell, or Touch
What type of questions require more than one word or sentence to answer?
Open-ended questions
What do you call a definition that requires a specific set of conditions to be true that is usually a method of measurement?
An operational definition
A hypothesis provides an informed opinion. What is your hypothesis based on that makes it "informed"?
Your research
Using the following experiment, identify the controlled variable:
Question: Does the amount of homework assigned to a class impact the level of energy the students have the next day?
Procedure: For the next 3 days, assign the same students homework of the same level of difficulty, but different amounts. For day 1, assign 30 min worth of work. Day 2, assign 1 hour worth of work. And day 3, assign 3 hours worth of work. Each day, ask the students on a scale from 1 - 10 what their level of energy is.
The level of difficulty of the homework
OR
The number of students
Which of the following can you observe (select all that apply):
a) How something looks when it moves
b) How something changes
c) What someone will do in the future
d) What the conditions are
a, b, and d
When we ask a question to get a better understanding of what we observe to be true, what is this called?
Curiosity
How would you know that a scale is NOT balanced?
If the beam is NOT parallel to base / bottom of the fulcrum, the scale is not balanced
Before writing a hypothesis, what is the first step in the process?
Identify what is being observed
Using the following experiment, identify the dependent variable:
Question: Does the amount of homework assigned to a class impact the level of energy the students have the next day?
Procedure: For the next 3 days, assign students homework of the same level of difficulty, but different amounts. For day 1, assign 30 min worth of work. Day 2, assign 1 hour worth of work. And day 3, assign 3 hours worth of work. Each day, ask the students on a scale from 1 - 10 what their level of energy is.
The dependent variable is the level of energy each student has.
Based on the following, which of these statements is NOT an observation:
Mila sees her dog leaving dirt pawprints in her house. She also smells a sour smell coming from her dog's direction. Mila then goes to pet her dog and the fur feels matted. She observes that her dog hasn't bathed in 6 weeks.
She observes that her dog hasn't bathed in 6 weeks.
If I've observed that the more students that are absent, the level of noise gets lower, what would be an open-ended question that would address this observation?
Does the number of absent students have an impact the noise level in the room?
What is the operational definition of standard unit of mass?
Place the potential standard unit onto one side of the scale
On the other side, place another potential standard unit
If the scale is not balanced, the objects cannot be standard
If the scale is balanced, the two objects can be standard units of mass
Provide a hypothesis that would switch the independent and dependent variables of the following experiment:
Question: "Why are there computers in the library?"
IV: The number of students in the library
DV: The number of computers in the library
There are students in the library because there are computers in the library.
Given
IV: The temperature of the room
DV: The number of students complaining
Provide an open-ended question that flips the roles of the independent and dependent variables.
How does the number of students complaining impact the temperature of the room?
