What is Science?. Science is a process we use to answer questions about what we OBSERVE.

Observation vs. Inference

Observation vs. Inference

Observations Observations- Using our five senses to gather information about the world around us. There are two types of observations. Qualitative & Quantitative.

Science Everything we know went through a testing process

I. Making Observations- Observations can be made several different ways. Observations can be put into two different categories; qualitative and quantitative.

1. Prediction: to tell something before it happens 2. Hypothesis: a possible answer to a question based on gathered information.

DO NOW What Is Science?? - In your own words, write down any ideas or thoughts to explain what science is all about! -Take out homework if you did not.

Scientific Method Terms. Observation / Conclusion Observation Conclusion Qualitative or quantitative descriptions Act of gathering information Ex: The.

 Observation is describing an object using your five senses (sight, hearing, touch, smell, & taste) or measurement (numbers).

The nature of science. Scientific knowledge is the product of observation and inference. Observations and Inferences.

INFORMATION GATHERED BASED ON OUR FIVE SENSES THERE ARE TWO TYPES OF OBSERVATIONS… Think about what we learned about observations…

Observations and Inferences Using your senses and making sense of your observations.

 When describing something, use only facts that you can see, feel, smell, taste and hear  This is not an opinion!!!!!

Scientific Process How science works!!. Observation Use your 5 senses –Smell –Taste –Touch –Hear –See Classify information.

Observations: What do you see? Science Process Skills The tools of Science.

Observation and Inference Notes. OBSERVATION OBSERVATION- – Information collected using your five senses (sight, smell, touch, taste and hear); facts.

Are they really necessary? Can you do science without doing observations?

Observation and Inference

9/9/14 Objective: What is discovery science? *Take out HW, keep for now Do Now: Write down 3 observations (things that you can actually see that are important.

Thinking Like a Scientist Science starts with an observation Observation – the process of gathering information in a careful, orderly way  Use your senses:

Properties of Matter. Matter  Matter is anything that has volume and mass and takes up space.

Reminders … 1.Cell phones, backpacks, food/drink 2.Signed papers 3.Office hours.

Observations Use one or more of your five senses to gather information

Section Notes Physical science focuses on nonliving things.

\ Observation & Inference. Observations Any information collected with your 5 senses. The skill of describing scientific events Quantitative- Is measureable.

How we look at things in science

Observation vs. Inference

Observation Observation: when studying something describe only facts that you can see, touch, smell and hear. You are not making any guesses. THIS IS.

Vocabulary Observation: Using the five senses of sight, sound, taste, smell, and touch to learn or collect information about an object. Observations are.

Observation & Inference. Observations Any information collected with the senses. The skill of describing scientific events.

Observation vs. Inference

Using one or more of your senses to gather information about an object or your surroundings. What are the senses we use in science class? Sight Touch.

Thinking like a Scientist Part I

Observation Observation: / information collected by using your five senses: see, smell, taste, touch, hear. / Usually a fact- something that others would agree with. / NOT an opinion or conclusion Observation: / information collected by using your five senses: see, smell, taste, touch, hear. / Usually a fact- something that others would agree with. / NOT an opinion or conclusion

What do you make observations about? / Color / Texture / Size / Weight / Shape / Smell / Color / Texture / Size / Weight / Shape / Smell

Qualitative vs. Quantitative / Qualitative: think “quality”. This is an observation that uses WORDS to describe something. / Quantitative: think “quantity”. This is an observation that uses NUMBERS to describe something. / Qualitative: think “quality”. This is an observation that uses WORDS to describe something. / Quantitative: think “quantity”. This is an observation that uses NUMBERS to describe something.

Tips… / Don’t use the word “like” when making an observation. That is not specific enough. Ex. “It feels like marshmallows…” (What do marshmallows feel like? SAY THAT!) / Don’t use the word “like” when making an observation. That is not specific enough. Ex. “It feels like marshmallows…” (What do marshmallows feel like? SAY THAT!)

Inference  a conclusion you make based on your observations.  This is not FACT. This is now your perspective based on a set of information and others may agree/disagree.  a conclusion you make based on your observations.  This is not FACT. This is now your perspective based on a set of information and others may agree/disagree.

Observation or Inference? / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g. / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g.

Observations… / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g. / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g.

Inferences / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g. / The object is red. / The object is an apple. / The object smells sweet. / The object is round. / The object has a bruise. / The object has a brown spot. / The object has a mass of 200g.
