true
What step comes after making a hypothesis?
Conduct an experiment.
Name one controlled variable.
Anything kept the same (amount of water, temperature, container, etc.)
What tool helps you see tiny things?
Microscope.
What is a conclusion?
Final step/What you learned from the experiment.
You can skip recording your data.
false

What should you wear to protect your eyes?
Safety goggles.
What does predict mean?

Experiments help answer scientific questions.
true
What is the final step of the scientific method?
Draw a conclusion and share your results.
A scientist waters two plants differently and measures height. What is the dependent variable?
Plant height.
Name two pieces of lab safety equipment.
Safety goggles, gloves, apron/lab coat.
Why do scientists repeat experiments?
To make sure their results are accurate.
If your hypothesis is wrong, your experiment failed.
False. Scientists still learn from their results.
