Question 2

What are the 8 steps in the Scientific Method?

Answer 2

Observation, Ask a question, Research, Form a hypothesis, Test the hypothesis, Record and analyze data, Draw the conclusion, and Report and evaluate

Question 3

What is the difference between accuracy and precision?

Answer 3

Accuracy is how close 1 measurement is to the true value. Precision is how close 2+ measurements are to each other

Question 4

What is the difference between matter, inertia, and mass?

Answer 4

Matter is anything made of atoms or parts of atoms. Inertia is a property of matter that causes all matter to prefer it’s present state of motion. Mass is the variable used to quantify the amount of inertia in an object.
