A student is preparing to conduct an experiment with an electromagnet. His hypothesis is: If I increase the number of times I wrap the wire around the nail, my magnet will grow stronger and pick up more paperclips.
What is the independent variable? ( Hint:The thing that is changed)
the voltage of the current
the number of times the wire is wrapped around the nail
the direction of the current flow
the number of pins picked up
An experiment should only be done once, or you might come up with different and confusing results.
True
False
Which is not an observation?
My cat is black and white
My cat is fat
My cat is hungry
My cat is eating
Which is an inference? (an inference is a conclusion you can draw from your observations)
My cat is black and white
My cat is fat
My cat is hungry
My cat is eating
if___,then___because___.
Define OBSERVATION:
looking at data
doing research
using 5 senses to gather information
talking about your experiment
Facts, figues and other evidence gathered through observation:
information
observations
inference
data
What is a hypothesis?
A question
A testable explanation

the process to answer a question
Which step of the scientific method would this scenario be:
You happen to notice that your cat is gaining weight since switching to the new cat food
Propose a hypothesis
Ask a question
Observation
Iterate
Which step of the scientific method would this scene be:
Why is my cat suddenly gaining weight?
Test your hypothesis
Make predictions
Propose a hypothesis
Ask a question
Which step of the scientific method would this scene be?
I've noticed that my cat is gaining weight since switching to the new food, so maybe the new food isn't as healthy for her.
Propose a hypothesis
Make a prediction
Test your hypothesis
Ask a question
Which step of the scientific method would this scene be?
If I switch to a higher quality cat food, my cat will start losing weight.
Test your hypothesis
Make a prediction
Iterate

What is the information about the natural world that is gathered through the senses and/or scientific instruments?
Testable
Investigation
Observation
Prediction

Are ants smaller than the beetles?
Are ants attracted more to sugar or salt?
How many ants are there in colony?
I think ants are attracted more to sugar than salt?
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...( Hint: What is being changed?)
The type of plant
The amount of sunlight
The type of music
The type of liquid
