UNIT 1: Thinking Like A Scientist

2-COLUMN NOTESWHAT 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 NOTESTHINKING 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 NOTESOBSERVING 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!)

2-COLUMN NOTESTHINKING LIKE A SCIENTIST

CHECKPOINT What senses can the skill of observation involve?

BOX OF SCIENCE

Day 1 - OBSERVING1.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 NOTESTHINKING 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

INFERENCE1.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 NOTESTHINKING 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 ACTIVITY-PREDICTION, 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

PREDICTION1.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

2-COLUMN NOTESTHINKING 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

MODEL1. 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.)
