The Scientific Inquiry is the route by which scientists ask questions, develop and carry out investigations, make predictions, gather evidence and suggest explanations. b.)NAME SOME IDEAS ABOUT THE NATURAL WORLD THAT HAVE CHANGED OVER TIME BECAUSE OF NEW OBSERVATIONS.

We could use instruments to study a tree. We could use a ruler or tape measure to determine the height and width of it. Also, if we were to test the temperature of boiling water, we could use a thermometer to check how hot the water is. 3.) WHAT IS DATA?

Data could be measurements, descriptions of what things are like, what is happening somewhere or other facts. INVESTIGATIONS: are reasonable approaches to solving a problem.

EXPERIMENTS: situations set up by a researcher to test an idea. SEQUENCING: when you arrange data into...
