2-COLUMN NOTES
WHAT IS SCIENCE?



Science – A way of learning about natural
world. Science includes all of the knowledge
gained by exploring the natural world.
Scientist – Anyone who uses the scientific
method as a process to attempt to answer
questions about the natural world.
Natural World – Everything that can be observed
either directly or indirectly using on or more
of your five senses.
2-COLUMN NOTES
THINKING LIKE A SCIENTIST


Scientists use skills such as observing,
inferring, predicting, classifying, and
making models to learn more about the world.
OBSERVING

-
-
Using one or more of your senses to gather
information. (sight, hearing, touch, taste and smell)
Look around the room, what do you see? What do
you hear or smell?
Partner up: Use one of the items provided by
Mrs. Dean to make at least 3 observations.
2-COLUMN NOTES
OBSERVING


There are two types of observations: quantitative
and qualitative.
Quantitative Observations:

Deal with a number or amount


Examples
 There are 14 tables in the room.
 I have 5 fingers on my left hand.
Qualitative Observations:

Deal with descriptions that cannot be expressed as a
number.

Examples
 The chairs are blue.
 This grape tastes sweet.
RED SOX PHOTO OBSERVATIONS
On the next slide you will see a photo. Each
group needs to come up with 2 qualitative and 2
quantitative observations.
 Divide your whiteboard in half.
 On the top half, write the observations on the
whiteboard (do not let the others see!)

CHECKPOINT

What senses can the skill of observation involve?
BOX OF SCIENCE
Day 1 - OBSERVING
1.Question – What do you want to know about the Box of
Science? Write it on your worksheet.
2.Read paragraph on OBSERVING in “Think Like A Scientist”
3.Make at least 6 observations about the “Box of Science.”
2-COLUMN NOTES
THINKING LIKE A SCIENTIST
INFERRING
When you explain or interpret the things you
observe.
 Example: If you see Mrs. Dean wearing her jacket, you
might infer that she is cold.
 Inferences are not always correct. Mrs. Dean may
have simply forgotten to taken off her jacket, or
maybe spilled something on her shirt and is trying to
hide it.

Checkpoint: Using your observations about the
room, make an inference about something you
observe.
RED SOX PHOTO INFERRING
On the next slide you will see the same Red Sox
photo.
 Read your observations. Now, come up with 2
inferences based on your observations.
 Write them on the whiteboard (do not let the
others see!)

BOX OF SCIENCE
INFERENCE
1.Read paragraph on inferring in our text.
2.Make at least 1 inference about the “box of science” based on
your observations from yesterday.
2-COLUMN NOTES
THINKING LIKE A SCIENTIST
PREDICTING
To make a forecast of what will happen in the future
based on past experience.
 Examples: The Red Sox will make the playoffs, but
will not win the world series this year.
 Predictions and inferences are closely related.
Inferences are attempts to explain what is happening
(current events), and predictions are forecasts of
what will happen (future events).

PARTNER ACTIVITYPREDICTION, INFERENCE OR
OBSERVATION
With your partner discuss and write down the difference
between an observation, inference and observation. How
are they related?
On your paper, identify the following as Prediction (P),
Inference (I) or Observation (O).
1. It is hot outside today.
2. The students are wearing shorts because it’s hot out.
3. We will have thunderstorms this afternoon.
4. The thunderstorms will have lots of lightening and
thunder.
5. The Red Sox will win the playoffs this year.
6. The water tastes like vinegar.
7. The fan is on.
8. The projector is hot.
9. The room is hot because the projector is on.
10. Tomorrow Mrs. Dean will use the projector during class.
BOX OF SCIENCE
PREDICTION
1. Read paragraph on prediction in our text.
2. Now, make a PREDICTION about what is going to happen
when we pour the blue liquid in the box.
BOX OF SCIENCE
All you get to know: We will put 750 mL of blue liquid in the Box.
1.Now, write a HYPOTHESIS based on your prediction.
2.If we put 750mL of blue liquid in the box, then
……………………...
3.Experiment Time!
DATA TABLE

Complete the data table and write a conclusion
on your worksheet

THINKING LIKE A SCIENTIST
MAKING MODELS
A representation of complex objects or process used to
help people understand things they cannot observe
directly.
 EXAMPLES: a computer image, diagram, picture or
graph

Look around the classroom. Give an example of a model
you see.
BOX OF SCIENCE
MODEL
1. THINK: How does it work? Draw a sketch (rough draft)
MODEL.
2. Two Heads Are Better Than One! Partner work to decide on
a final MODEL & COMMUNICATE. (You will have tomorrow
to work on this & present to class.)
