OBSERVATIONS
Name the 5 senses you use in order to make an observation
Sight, Hearing, Smell, Touch, Taste
What is an INFERENCE?
What you think or decide based on your observations
What is a HYPOTHESIS
An educated guess based on our observations and knowledge.
The order of events that you plan to make happen to perform an experiment is called this. (example: you had to give me a list of exact instructions to get me through the door or to make a sandwich)
Procedure
If Mr Burke is growing plants to see which type of liquid helps them grow fastest, he will give them all 4 ounces of liquid each day at noon. All the plants are on the same windowsill, same size, and same amount of soil. He gives one set of plants water and the other set of plants iced coffee. He measure their height each day and records it in his notebook
What is the IV (Independent Variable)
The type of liquid
This type of observation uses numbers and measurements
QUANTITATIVE Observation
OBSERVATION OR INFERENCE?
The spider will probably make a web in the corner of the room because it is dark there
INFERENCE
What is a VARIABLE ?
Anything that can change or be changed
Which step of the scientific method do you do first?
A) Make observations and record the results
B) Make a hypothesis
C) Ask a testable question
C) Make a testable question

What is the DEPENDENT VARIABLE
The height of the plants
This type of observation uses descriptions to make observations.
QUALITATIVE observations
OBSERVATION VS INFERENCE?
A spider has eight legs
OBSERVATION
What is the INDEPENDENT VARIABLE in an experiment?
Anything that is changed or manipulated in an experiment. The "cause" in a cause and effect relationship
When do you have to repeat an experiment?
A) When your hypothesis is proven correct
B) When your hypothesis is proven incorrect
C) You repeat it multiple times regardless of whether your hypothesis is correct or not
C) You repeat it multiple times regardless of whether or not your hypothesis is correct or not

Name TWO constants in this experiment
"There are 18 students in the class" is this type of observation
Quantitative
OBSERVATION OF INFERENCE
It is raining outside
OBSERVATION
What is the DEPENDENT variable in an experiment ?
The variable that is affected or changed based/depending on the independent variable. The "effect" of a cause and effect relationship.
An IF _______ THEN _______ STATEMENT is COMPLETELY DIFFERENT AND HAS NO CONNECTION to a CAUSE AND EFFECT statement
False.
If is the CAUSE and
THEN is the effect

All the plants are on the same windowsill, same size, and same amount of soil. He gives one set of plants water and the other set of plants iced coffee. He measure their height each day and records it in his notebook
What could his hypothesis be for this experiment?
If he gives the plants coffee, then they wont grow as fast.
(Answers can vary)
"The sweaters that the students are wearing are grey" is this type of observation
QUALITATIVE
OBSERVATION OR INFERENCE
It will most likely rain for the next two hours
INFERENCE
What are CONSTANTS in an experiment?
The things that stay the SAME in every experiment to determine that is it the independent variable that causes the change in a situation
Which type of TAKIs did Mr Burke like the most/dislike the least of the three types we tried yesterday
A) FUEGO
B) BLUE HEAT
C) GUACAMOLE
FUEGO.
Guacamole was horrible and smelled like wet cardboard cutouts of feet

He measure their height each day and records it in his notebook.
Why do the plants have to be the same for this experiment?
To see if the liquid affects the same types of plants because different types may react differently, and thats a completely different experiment.
