200
describes something that has length and width, but not height
What is two-dimensional?
300
the process of asking questions and searching for answers
What is an inquiry?

How can working in a team be helpful for scientists?
Each member of the team can work on a different part of the investigation. A team can work faster. A team might have more ideas than one scientist working alone.

What is one piece of data scientists can gather by using telescope?
Scientists can gather information about the atmosphere, planets, stars, and astroids.

Why do scientists use scientific methods?
Scientific methods help scientists draw conclusions.
400
What do scientists base their explanations on?
Scientists base their explanations on evidence.

Why do scientists use models?
To find out things they cannot test on actual objects

Why is it important for scientists to keep track of the information they find in reference materials?Other
scientists can then easily find the materials.

Why is it important to make precise measurements?
It helps scientists who share information know what other scientists have observed. It helps scientists make accurate observations.
500
Why do scientists often compare their methods, procedures, and results with other scientists?
By comparing, scientists can work to find results that can be retesting.
500
Why is it important for scientists to have reliable data?
Reliable data can be more useful in the future. Scientist want to make experiments and observations based on true information so their results are correct.

Why would a model built from large amounts of information be more useful than a model built from only a little information?
A model built from large amounts of information would be more accurate and would be more useful because more factors are taken into account.
