Try to guess these pictures…

It’s a tape dispenser!

It’s a crayon!

It’s a shoelace!

How did you guess what the picture was? What clues did you use to make the best guess

possible?

Observations, Inferences, Scientific Questions, OH MY!

“A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.”

– Isaac Asimov

• An observation is the act of using one or more of your senses to gather information and taking note of what occurs.

• This includes all five senses….– The color of an apple– The taste of pizza– The sound of a trumpet– How a cat feels– The smell of fresh laundry

Observations

Qualitative vs. Quantitative• Qualitative observations describe the quality of objects by

using words. – The color of an apple– The taste of pizza– The sound of a trumpet– How a cat feels– The smell of fresh laundry

Qualitative vs. Quantitative• Quantitative observations use numbers to describe

things.– Think “quantity”

• The length of a football field• The temperature of ice cream• The number of people in a stadium• The volume of a bottle of soda

Qualitative vs. Quantitative

Qualitative: • The type of ice cream• The color of the ice cream• The ice cream is cold

Quantitative:• The exact temperature of the ice cream• How many ice cream cones there are

Inferences

• After we make observations, we can then make assumptions – called inferences.

• Inferences are the assumptions or conclusions that you make based on the observations you make.

Inferences• If you see a 12 year old girl, who

is 5’1” tall, who is wearing a blue skirt and a white button down shirt, and a burgundy crosstie, you might infer that she attends Summit.

• How old she looks, her height, and what she is wearing are all observations. They are facts.

• You conclude, or make an inference, that she attends Summit, based on the information that the observation gave you.

You try!

Independent Practice

• Complete the worksheet on observations

• The top half has you identify qualitative and quantitative observations.

• The bottom half has you write your own observations and inferences.

Scientific Method

• When scientists perform experiments, they follow very specific steps.

• These steps are called the Scientific Method.

Scientific Method

• The steps of the Scientific Method are:1. Asking a question2. Performing background

research3. Forming a hypothesis4. Testing the hypothesis 5. Analyzing data and drawing

conclusions6. Communicating results

Scientific Questions

• All experimental investigations begin with a question!

• A good scientific question is…– Always testable and Avoids

opinions• Testable: We can do an experiment

to test our hypothesis.

– Specific• Example: Does handling frogs cause

warts? Instead of something like; Can an animal mess up your skin?

– Keeps the scientist focused on one experiment

Scientific Questions

• Scientific questions cannot be based on opinion because everyone’s opinion might be different and not provable.– “Which flowers are prettier, daisies or roses?” cannot be

answered with an investigation, because the answer is an opinion.

– A better question could be “Do daisies or roses grow faster?” • Scientific questions must not be based on any kind of

personal preference or moral values. • They also must be related to phenomena that can be

measured (supernatural does not count).

Practice #1

Does hot water freeze faster than cold water?Is it a good scientific question? YES NO

It is testable, you could freeze hot water and cold water. It also avoids opinions, this is an observable fact.

It specifically explains what is being done (freezing) and to what substances (hot and cold water)

It keeps the scientist focused because they are only changing one thing – the type of water.

A:

S:

Practice #2

Do cats make better pets than dogs?Is it a good scientific question? YES NO

It is not testable, it would be difficult to measure and explain “better.” It does not avoid opinion; who makes better pets is an opinion.

It is not very specific, “better” is broad and vague.

It does not keep the scientist focused because it is not setting them up for just one experiment.

Rewrite it: • Are dogs or cats more likely to come

to the door when you come home from school or work?

Tips for Writing Testable Questions

1. Begin by listing several questions on a topic about the natural world.2. Try to eliminate questions that cannot be answered by gathering

evidence.3. Break broad questions that can be investigated one at a time.4. Word questions in a way that allows them to be answered by an

investigation or experiment. 5. Be sure that the question identifies a relationship or factor you can

investigate.

Here’s how you could begin…• What is the relationship between…?• What factors cause…?• What is the effect of…?

Popcorn Article

• With your table group, you will read an article about the way popcorn is made.

• While reading, you should identify some observations (qualitative/quantitative) and testable scientific questions that were mentioned in the article.

• Try to see if you have some other questions of your own!

12 min




– Isaac Asimov

Independent Practice

• Use the popcorn article you just read during the guided practice and create some observations about popcorn. Try to make different ones from the article!

• Then, use those observations to write your own scientific question – different from one in the article.

• You may write a few different questions.

• When you think you have a good, testable question, have me check it for you. You will use this for the next couple class periods!
