Observation/Inference
A type of observation that uses all 5 senses.
What is qualitative?
Created from your observations and inferences. Needs to be something we can solve.
What is a problem/question?
A cause and effect statement, including the independent and dependent variables; predicts what you think will happen.
What is a hypothesis?
The variable that is changed and tested.
What is independent variable?
The tool used to measure mass.
What is a triple beam balance?
A type of observation that uses numbers and quantities.
What is qualitative?
True or false: Creating a problem leads us to develop observations.
What is false?
Identify the independent and dependent variables in the following hypothesis: If acid rain is in water, then fish populations will increase.
IV: "What is acid rain in water"?
DV: "What is fish populations increasing"?
The variable that is measured; the effect.
What is dependent variable?
The tool used to measure length.
What is a meter stick/ruler?
An educated guess based off of observations.
What is an inference?
True or false: Problems are the main step that develops the rest of the experiment.
What is false?
Identify the independent and dependent variables in the following hypothesis: If trees have leaves then bird nests will increase.
IV: "What is trees having leaves"?
DV: "What is bird nest counts"?
The variable that has to stay the same.There are always multiple of these.
What is control variable?
The base unit to measure volume.
Liters
The palo verde tree is 28 feet tall and army green with blood red flowers. This is an example of what?
What is observation?
Create a problem or question based on these observations and inferences.
*Teacher is smiling
*Teacher plans fun lesson
*Teacher hands out candy
*I think the teacher is happy
Examples of problem:
What made the teacher happy?
How can I continue to keep the teacher happy?
Form a hypothesis based on the following question:
"What effect does studying with music have on student test scores?"
If a person studies with music, then their test scores will be higher.
Identify the INDEPENDENT VARIABLE in this statement:
If I listen to country music, then I will do worse on my science test.
What is "listening to country music"?
The middle of a curve in the graduated cylinder; the point you read to measure volume.
Meniscus
All animals that can fly are birds. This is an example of what?
What is an inference?
Create a problem or question based on the hypothesis: If chocolate is given to teachers, the the amount of homework will decrease.
What effect does chocolate have on homework given?
Form a hypothesis based on the following problem:
"What effect does food color have on the amount of food fish eat?"
If a fish is fed red (or colored) food, then it will eat more.
