1 - Scientific Investigation

Scientific investigation is all about exploring questions and finding answers by thinking like a scientist. When scientists investigate, they use skills like observing (noticing details with their senses), making inferences (drawing conclusions based on what they see), and predicting (making educated guesses about what might happen). They also follow steps known as the scientific method, which helps them keep their experiments organized and fair.

Hypothesis

Hypothesis definition: A possible explanation for a set of observations or answer to a scientific question. It must be testable and is written as 'If..., then...'

Variables

Definition of variables: independent, dependent, and constants

What I change.

The data we collect!

What I keep the same.

Types of Data

Qualitative and quantitative data definitions and examples

Qualities or how things look.

Colored number blocks representing quantities

Quantities or numbers

Match the variable type to its definition.

Dependent variable		What I keep the same throughout testing.
Independent variable		The data we collect from changes.
Controlled variables		What I change in the experiment.

Metrics

Scientists collect data using the International System of Units (SI), a.k.a. the metric system. This table summarizes important facts about measuring with SI units.

Measurement	SI Unit	Abbreviation	Measuring Instrument
length	meter	m	Metric ruler
mass	gram	g	Balance (triple beam balance or electronic)
volume (liquid)	liter	L	Graduated cylinder
volume (solid)	Centimeter cubed	cm$^3$	Ruler or graduated cylinder
density	Grams per centimeter cubed	g/cm$^3$	Balance and measuring device for volume
weight	Newton	N	Spring scale
temperature	Degrees Celsius or Kelvin	$^\circ$C, K	Thermometer
time	second	Sec or s	Clock or stopwatch

You can easily convert from one metric unit to another using the “ladder method.”

Scientific Notation

Scientific notation is an easy way to write and compare very large and very small numbers, including measurements.

Examples of writing 500, 7,700,000,000, and 0.0000000086 in scientific notation.

Match each SI unit to its corresponding measuring instrument.
