Science is the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested.

Textbook Definition:

Everyday Definition: Science is observing, studying, and experimenting to find out more about the natural world around us.

Science is observing, studying, and experimenting to find out more about the natural world around us.

Everyday Definition:

Textbook Definition: Science is the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested.

What is Science?

16

Observations

We are constantly making observations of the world around us.

Observations:• Collecting information about the world using one of our five senses.

17

Types of Observations

There are two main types of observations:

• Qualitative observations– A quality or characteristic of a given object or event.

ex: The sky is blue.

• Quantitative observations– An observation in the form of a quantity (using numbers).

ex: The desk is 1 meter tall.– Things we can measure.

Go back to your list of observations from the candle lab. Circle the observations that are qualitative and put a box around the ones that are quantitative.

18

Making Sense of Observations

Our brains are constantly trying to make sense of our observations.

Inference:• making a conclusion about our observations based on prior knowledge, reasoning, or evidence.

Reading Skillfully Worksheet

• "Reading Skillfully" is something that we'll do several times throughout the year.

• Each one is a worksheet made to help teach you about a topic while also helping you get better at scientific reading

23


• One sheet is the reading itself.

• The other sheet is questions for you to answer

• Instead of just reading and answering questions, you're going to follow a specific process to learn as much as you can from this reading

24


• First, look at the reading page without actually reading the words. Instead, look at the pictures.

• On the answer sheet, draw each picture in one of the boxes on the left side.

• Then, read. After reading, do your best to describe the picture in a complete sentence.

25


• Next, write down the title of the reading and any words that are in bold in the reading

• Lastly, read each paragraph one at a time.

• Choose the most important sentence in each paragraph and underline it. Then, copy it on the answer side of your paper.

26

Reading Skillfully Worksheet• When you finish, turn in the blue answer worksheet to the basket up front.

• Keep the reading sheet and add it to your notes. That way, you can look back at it to study from later in the unit.

27

Theory vs. Hypothesis vs. Law

• Often in science, vocabulary words mean something different than they might in everyday life.

• "Theory" and "Law" are good examples.

https://www.youtube.com/watch?v=lqk3TKuGNBA


28


• Theory: A statement that explains how a natural process works.

• This is not a "hunch" or a "guess" and is based on repeated experimental results

• Law: A statement that describes what happens (and will always happen) during a natural process.

• Laws are not necessarily better or more proven than theories. Both are supported by huge amounts of evidence.

Day 4 Question(s): What is an inference?

Make 2 inferences about the following picture:


31


• Hypothesis: A possible explanation, based on what you know or observe, that can be tested.

• Many experiments start with hypotheses, which can then be proven true or false by the results.

• A lot of the time, what we would call a "theory" in everyday language would be called a "hypothesis" in science.

• A "theory" in science has been tested enough that people are convinced it is true.

How do we do science?

• Science usually starts with observations

• A person (maybe a scientist, maybe just an average person) observes something. This leads to...

A Question!

Scientists want to learn more about the observation, so they create a question that they want to find an answer to.

35

Scientific Questions

Scientific Question: A testable question that a scientist wants to find an answer to.

A scientific question usually takes the form:

"How does __________ affect __________?"

36

Scientific Question Practice

• For example, if a scientist wanted to know how fast snow would melt in different temperatures of air, she could ask:

• How does air temperature affect the speed of snow melting?

You try it!

• If you want to know how much water people drink after different amounts of exercise:

• How does __________ affect __________?

37

Scientific Question Practice

• If you want to know how many shots the CPHS basketball team will make depending on how long they practice:

• If you want to know if studying longer will help your grade on your science tests:

38

Hypothesis

• Hypothesis: A possible explanation, based on what you know or observe, that can be tested.

A hypothesis usually takes the form:

"If ________, then ________, because _________."

39

Hypothesis Practice

• For example, if a scientist wanted to know how fast snow would melt in different temperatures of air, his hypothesis might be:

• If the air is hotter, then snow will melt faster, because ice melts when it gets warm.

You try it!

• If you want to know how much water people drink after different amounts of exercise, your hypothesis could be:

• If ______, then _______, because _______.

42

Hypothesis Practice

• If you want to know how many shots the CPHS basketball team will make depending on how long they practice, your hypothesis is:

• If you want to know if studying longer will help your grade on your science tests, your hypothesis is:

43

Designing an Experiment

• Your question should help you choose your variables for your experiment.

• Variable: A factor that changes in an experiment

• Independent Variable: What the scientist changes on purpose; what the scientist is testing the effect of (the cause)

• Dependent Variable: The variable that responds to the change in the independent variable; what the scientist measures (the result)

44

Designing an Experiment

• Anything that is not one of the two variables should be kept constant (controlled).

• Constant (Control): A factor that stays the same in an experiment

• Constants are needed so that you know that changing the independent variable caused the change in the dependent variable

45

Designing an Experiment Practice

• A good scientific question is always written:

• "How does (Independent Variable) affect (Dependent Variable) ?

• Example: How does air temperature affect how fast snow melts?

• Independent Variable:

• Dependent Variable:

Everything else should be kept constant:

51

Writing Procedures

With a partner, write out step by step instructions for how to wash your hands.

Assume the person reading the instructions has never washed their hands before.

52

Writing Procedures

A written procedure is a stepbystep guide to direct any reader through a task.

• Steps should be numbered• Steps should be written in presenttense• Steps should be easy to understand and have enough detail for anyone to follow (replicate)

• Procedure for an experiment should include steps that allow for a sufficient amount of quantitative data to be collected.

53

57

Why do Experiments?

• The goal of experiments is not necessarily to always be right.

• A good experiment should help you learn whether your hypothesis is right or wrong; it's ok to be wrong
