Vocabulary
The variable that the scientists are manipulating in an experiment
What is the independent variable?
"Using fertilizer will make the plants grow taller than not using fertilizer because it will provide the nutrients needed to promote growth" is a ________
What is a hypothesis?
The first step of the scientific method
What is asking a question/ identifying a problem?
Write a hypothesis for the question: Will an Owala keep water cold throughout the school day?
An Owala will keep water colder than a plastic water bottle through the school day because it is better insulated.
Can a scientist ever definitively say that their hypothesis is completely right? Why or why not?
No, nature cannot talk and tell us if we are correct. We just need to use the evidence we have.
The variable that scientists are measuring, the variable that responds
What is the dependent variable?
The group the experimenter tests on
What is the experimental group?
The second step of the scientific method
What is collecting observations?
Scarletts classroom is very hot during the day. She wants to make sure her water stays as cold as possible throughout her school day. Her friends told her to get an Owala because it keeps the water colder for longer. One morning she put out to water bottles, an Owala and a regular plastic bottle, with the same amount of ice in each. She then took their temperatures at the end of the school day.
What is the independent variable? How do you know?
The Owala/ plastic bottle. That is what she is going through and changing.
If a hypothesis or theory later becomes rejected, does that mean that science is weak or failed? Explain your answer?
Science has not failed, we just learned more new information
What is a collection of hypotheses that have been tested and accepted many times?
What is a theory?
"It took the dog 10 seconds to run across the field" is a _______ observation
The third step of the scientific method
What is forming a hypothesis?
Scarletts classroom is very hot during the day. She wants to make sure her water stays as cold as possible throughout her school day. Her friends told her to get an Owala because it keeps the water colder for longer. One morning she put out to water bottles, an Owala and a regular plastic bottle, with the same amount of ice in each. She then took their temperatures at the end of the school day.
What is the dependent variable?
The temperature of the water at the end of the day
Data that is collected based off of your senses
What is qualitative data?
"The large butterfly is better than the smaller butterfly" is a ________ observation
What is a subjective observation?
The fourth step of the scientific method
What is performing a controlled experiment?
Scarletts classroom is very hot during the day. She wants to make sure her water stays as cold as possible throughout her school day. Her friends told her to get an Owala because it keeps the water colder for longer. One morning she put out to water bottles, an Owala and a regular plastic bottle, with the same amount of ice in each. She then took their temperatures at the end of the school day.
What is the control?
The plastic water bottle
Data that is collected based on using an instrument of measurement
What is quantitative data?
The group the experimenter keeps the same
What is the control group?
The fifth and sixth steps to the scientific method
What is recording and analyzing data and forming a conclusion?
Scarletts classroom is very hot during the day. She wants to make sure her water stays as cold as possible throughout her school day. Her friends told her to get an Owala because it keeps the water colder for longer. One morning she put out to water bottles, an Owala and a regular plastic bottle, with the same amount of ice in each. She then took their temperatures at the end of the school day.
What is a constant?
Putting the same amount of ice
