Science
Used when a scientist cannot test on the real thing.
Investigation
The process of answering a question through various methods
Model
The study of the natural world
Survey

A step by step list of what the scientist will do in an experiment
Experiment
Materials list
Product
Procedure
Gathering information using one or more of the five senses
(a)
What could they do to make sure their results are valid?
Avi is comparing two brands of batteries. He uses two identical flashlights to see which battery lasts longer. What is the best reason for this experiment to be repeated?
to check whether the results are consistent
to make sure the flashlights were not broken
to check that no one turned off one of the flashlights
to make a prediction about a different brand of battery
Manuel and Chris are investigating the kinds of flowers that attract butterflies. They took a survey of people who work at local garden shops and nurseries. What is the best reason they should take careful notes about how they carry out their survey?
so they do not leave out any steps
so they can take out answers they do not like
so their conclusions can be checked with another survey
so they can decide whether they want to finish
their investigation
Which of these observations are scientifically testable?
Ants are more fun to watch than beetles
Trees that are tall are better than trees that are short
Science is more fun than math
Green apples don't go bad as fast as red apples

What is the best way to make sure your data is accurate in an experiment?
Do research
Do your experiment multiple times
Make a prediction

Edena compares the time of one back-and-forth swing for each of five pendulums. She concludes that the longest pendulum swings back and forth the most slowly.
However, she does not record the lengths of the strings, the times, or the masses she uses.
What is the best reason that the results of Edena’s experiment are not very useful?
She did not decide if her hypothesis is supported.
She did not write down a prediction before beginning.
The experiment cannot be repeated to confirm her results
The experiment should have tested different types of string
