Warm Up #1 What are 5 questions that you have about the world around you?

Lesson 1: Understanding Science Nature of Science (NOS): Scientific Explanations

Essential Questions What is scientific inquiry? What are the results of scientific investigations? How can a scientist minimize bias in a scientific investigation?

Science – the investigation and exploration of natural events and of the new information that results from those investigations Describe each of the following: Life Science – Earth Science – Physical Science -

Science – the investigation and exploration of natural events and of the new information that results from those investigations Describe each of the following: Life Science – the study of all living things Earth Science – the study of Earth, including its landforms, rocks, soil, and forces that shape Earth’s surface Physical Science – the study of chemistry and physics; study interactions of matter and energy

Which branch of science does it belong to?

Scientific Inquiry BrainPOP – Scientific Method Pass our Scientific Method handout

Key Terms Observation – the act of watching something and recording what occurs Inference – a logical conclusion based on available information or evidence Hypothesis – a possible explanation about an observation that can be tested by scientific investigations Prediction – a statement of what will happen next in a sequence of events; uses “If…, then ….” statement

Classify the statements as an observation or inference The apple covering is red. The apple is edible. There are seeds inside the apple.

Compare and Contrast Scientific Theory Scientific Law

Compare and Contrast Scientific Theory: an explanation of observations or events based on knowledge gained from many observations and investigations Scientific Law: describes a pattern or an event in nature that is always true States that something will happen Tries to explain why something happens Usually based on one well-supported hypothesis that states that something will happen Contains many well-supported hypotheses

Evaluating Scientific Evidence Critical thinking – comparing what you already know with the information you are given in order to decide whether you agree with it. What are the following: Sampling Bias Blind study Repetition

Evaluating Scientific Evidence Critical thinking – comparing what you already know with the information you are given in order to decide whether you agree with it. What are the following: Sampling: studies small amounts of something to learn about the larger whole Bias: intentional or unintentional prejudice towards a specific outcome Blind study: reduces bias where investigator, subject, or both don’t know which item they are testing Repetition: doing an experiment more than 1 time

Safety in Science What must you do to ensure you are safe when you are conducting an experiment?
